格陵兰冰盖是现代北半球唯一的陆地冰盖，其物质平衡变化对全球海平面上升具有重要的影响。同时，格陵兰冰盖融化将导致大量的淡水注入到北大西洋，减弱北大西洋经圈翻转环流，进而影响到全球气候。因此，本文利用最新的CMIP5模式预估结果和冰盖模式SICOPOLIS，模拟研究了21世纪格陵兰冰盖物质平衡的变化以及冰盖融化对全球海平面上升的贡献。在RCP 4.5和RCP 8.5情景下，SICOPOLIS模拟结果表明，格陵兰冰盖融化将导致全球海平面在2100年时分别上升0−16 cm和0−27 cm（相对于1986−2005）；如果考虑未来冰盖底部滑动加倍，全球海平面将分别上升7−22 cm和7−33 cm。基于多模式集合平均的结果，全球海平面在RCP 4.5和RCP 8.5情景下将分别上升4 cm和7 cm（考虑底部滑动增强时，分别为10 cm和13 cm）。上述海平面预估的不确定性正反映了在相同的外部强迫下全球模式预估结果的离散性，而评估模式并选择性的使用模式可以在一定程度上减小海平面预估的不确定范围。</div> </td> </tr> <tr height="20"> <td> </td> <td> </td> </tr> </tbody> </table>

本文研究了1951-2010年期间我国东北冬季降雪的长期变化. 结果显示, 相对于1951-1985年, 1986-2010年间的降雪大约增加了20%. 进一步分析表明降雪的增加可能与东亚冬季风的减弱密切相关. 同时, 本研究还探讨了其中的有关物理机制. 东亚冬季风的减弱导致来自北方的冷空气减弱, 东北亚沿海海温偏暖; 使得从海洋蒸发到大气的水汽增多, 于是输送到东北的水汽也相应增多. 此外, 由于东亚冬季风的减弱, 从东北南部、东部以及西部输入的水汽都增多, 从而大气中的水汽含量增加, 降雪随之增强. 从大气环流环流的角度分析表明, 东亚冬季风的减弱使得低层辐合、高层辐散加强, 有利于垂直运动的加强, 为降雪增多提供了相应的动力条件
YANYAN HUANG, HUIJUN WANG, PING ZHAO, 2013: Is the Interannual Variability of the Summer Asian-Pacific Oscillation Predictable?. Journal of Climate, 26, 3865-3876
The summer (June-July-August) Asian-Pacific Oscillation (APO) measures the interannual variability of the large-scale atmospheric circulation over the Asian-North Pacific sector. In this study, we assess the predictability of the summer APO index interannual variability and the associated atmospheric circulation anomalies using the 1959-2001 hindcast data from the European Centre for Medium-range Weather Forecasts (ECMWF), Centre National de Recherches Météorologiques (CNRM), and the Met Office (UKMO) general circulation models from the Development of a European Multi-model Ensemble System for Seasonal to Interannual Prediction project. The results show that these models predict well the summer APO index interannual variability and have higher skill for the North Pacific upper-tropospheric temperature than for the Asian upper-tropospheric temperature. Meanwhile, the observed APO-related atmospheric circulation anomalies in the South Asian high, the tropical easterly wind jet over the Asian monsoon region in the upper troposphere, the subtropical anticyclone over the North Pacific and the summer southwest monsoon over Asia in the lower troposphere are reasonably well predicted in their spatial patterns and intensities. Compared with the observations, however, these models display low skill in predicting the long-term varying trends of the upper-tropospheric temperature over the Asian-North Pacific sector or the APO index during 1959-2001.
Wang, T., H. J. Wang, O. H. Otterå, Y. Q. Gao, L. L. Suo, T. Furevik, and L. Yu, 2013: Anthropogenic agent implicated as a prime driver of shift in precipitation in eastern China in the late 1970s. Atmospheric Chemistry and Physics, 13, 12433-12450
Observation shows that eastern China experienced an interdecadal shift in the summer precipitation during the second half of the 20th century. The summer precipitation increased in the middle and lower reaches of the Yangtze River valley, whereas it decreased in northern China. Here we use a coupled ocean–atmosphere general circulation model and multi-ensemble simulations to show that the interdecadal shift is mainly caused by the anthropogenic forcing. The rapidly increasing greenhouse gases induce a notable Indian Ocean warming, causing a westward shift of the western Pacific subtropical high (WPSH) and a southward displacement of the East Asia westerly jet (EAJ) on an interdecadal timescale, leading to more precipitation in Yangtze River valley. At the same time the surface cooling effects from the stronger convection, higher precipitation and rapidly increasing anthropogenic aerosols contribute to a reduced summer land–sea thermal contrast. Due to the changes in the WPSH, the EAJ and the land–sea thermal contrast, the East Asian summer monsoon weakened resulting in drought in northern China. Consequently, an anomalous precipitation pattern started to emerge over eastern China in the late 1970s. According to the model, the natural forcing played an opposite role in regulating the changes in WPSH and EAJ, and postponed the anthropogenically forced climate changes in eastern China. The Indian Ocean sea surface temperature is crucial to the response, and acts as a bridge to link the external forcings and East Asian summer climate together on a decadal and longer timescales. Our results further highlight the dominant roles of anthropogenic forcing agents in shaping interdecadal changes of the East Asian climate during the second half of the 20th century
Wang, T., and H.J. Wang, 2013: Mid-Holocene Asian summer climate and its responses to cold ocean surface simulated in the PMIP2 OAGCMs experiments . Journal of Geophysical Research, 118, 4117-4128
In this study, we investigated changes in Last Glacial Maximum (LGM) sea surface temperature simulated by the Paleoclimate Modelling Intercomparison Project (PMIP) muitlmodels and reconstructed by the Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface (MARGO) project, focusing on the model-data comparison. The results showed that the PMIP models produced greater ocean cooling in the North Pacific and Tropical Ocean than that in the MARGO, particularly in the Northwestern Pacific, where the model-data mismatch was larger. All the models failed to capture the anomalous east-west SST gradient in the North Atlantic. In addition, large discrepancies among the models could be observed in the mid-latitude ocean, particularly for the models in the second phase of the PMIP. Although they gave some better agreement with the MARGO, the latest models in the third phase of the PMIP could not show substantial progresses in simulating the LGM ocean surface condition. That is, the improvements in the modeling community were still needed to describe the SST in order to better understand climate during the LGM.</div> </td> </tr> <tr height="20"> <td> </td> <td> </td> </tr> </tbody> </table>
Liu Jiping, Judith A. Curry, Wang Huijun , Mirong Song, and Radley M. Horton, 2012: Impact of declining Arctic sea ice on winter snowfall. Proc. Natl. Acad. Sci, DOI：10.1073/, pnas.1114910109,
While the Arctic region has been warming strongly in recent decades,anomalously large snowfall in recent winters has affected large parts of North America, Europe, and east Asia. Here we demonstrate that the decrease in autumn Arctic sea ice area is linked to changes in the winter Northern Hemisphere atmospheric circulation that have some resemblance to the negative phase of the winter Arctic oscillation. However, the atmospheric circulation change linked to the reduction of sea ice shows much broader meridional meanders in midlatitudes and clearly different interannual variability than the classical Arctic oscillation. This circulation change results in more frequent episodes of blocking patterns that lead to increased cold surges over large parts of northern continents. Moreover, the increase in atmospheric water vapor content in the Arctic region during late autumn and winter driven locally by the reduction of sea ice provides enhanced moisture sources, supporting increased heavy snowfall in Europe during early winter and the northeastern and midwestern United States during winter. We conclude that the recent decline of Arctic sea ice has played a critical role in recent cold and snowy winters.</div>

In this paper, studies on extreme climate in China including extreme temperature and precipitation, dust weather activity, tropical cyclone activity, intense snowfall and cold surge activity, ﬂoods, and droughts are reviewed based on the peer-reviewed publications in recent decades. The review is focused ﬁrst on he climatological features, variability, and trends in the past half century and then on simulations and projections based on global and regional climate models. As the annual mean surface air temperature (SAT) increased throughout China, heat wave intensity and frequency overall increased in the past half century, with a large rate after the 1980s. The daily or yearly minimum SAT increased more signiﬁcantly than the mean or maximum SAT. The long-term change in precipitation is predominantly characterized by the so-called southern ﬂood and northern drought pattern in eastern China and by the overall increase over Northwest China. The interdecadal variation of monsoon, represented by the monsoon weakening in the end of 1970s, is largely responsible for this change in mean precipitation. Precipitation-related extreme events (e.g., heavy rainfall and intense snowfall) have become more frequent and intense generally over China in the recent years, with large spatial features. Dust weather activity, however, has become less frequent over northern China in the recent years, as result of weakened cold surge activity, reinforced precipitation, and improved vegetation condition. State-of-the-art climate models are capable of reproducing some features of the mean climate and extreme climate events. However, discrepancies among models in simulating and projecting the mean and extreme climate are also demonstrated by many recent studies. Regional models with higher resolutions often perform better than global models. To predict and project climate variations and extremes, many new approaches and schemes based on dynamical models, statistical methods, or their combinations have been developed, resulting in improved skills. With the improvements of climate model capability and resolution as well as our understanding of regional climate variability and extremes, these new approaches and techniques are expected to further improve the prediction and projection on regional climate variability and extremes over China in the future.</div>

古气候重建显示，古近纪（大约35-60百万年之前）亚洲的气候格局是一种带状格局。一条宽广的带状干旱带/半干旱带控制着我国大部分地区。然而，以前的研究并没有揭示这条带状干旱带/半干旱带的形成机制。在这篇新的文章中，我们用全球大气模式，在更好的古地理重建条件下，模拟了早始新世50百万年前亚洲气候；并考虑古气候对轨道参数，地形，植被和海温及大气CO2浓度的敏感性。我们模拟显示，一条年降水量小于800mm的带状干旱/半干旱带纬向分布在古北纬20至40度之间。根据柯本气候分类，这条干旱带属于沙漠（BWh）和草原（BSh）气候。类似于地中海气候出现在我国西北内陆及中亚。这一模拟结果与已有的古气候格局重建相一致。模拟表明，这一宽广的带状干旱带形成的主要原因是受到50百万年前副热带高压的控制。由于50百万年前，全球温度大约比现代高出12摄氏度，副热带的分布范围比现代更加靠北；当时的高温使得干旱带的分布范围变宽，其北界可以达到古北纬40度附近。敏感性试验表明，地球轨道参数的变化，是最有可能在当时放大海陆热力差异并加强季风环流的因素；季风气候可以 在早始新世短暂出现，但对于整个早始新世气候来说，并不起主导作用。<br /> 这一研究，使得我们对古近纪亚洲古气候的理解更加完善。过去我们一般认为，在带状气候格局下，季风气候是不可能存在的。但这个研究证明，在带状气候格局下，季风气候可以短暂出现，虽然它并不起主导作用。</div>

本文通过多变量经验正交函数展开（multivariate EOF，简称 MV-EOF）研究了东亚冬季风各系统成员的协同关系，再运用单变量EOF定义单个系统的强度系数。从而给出能够反映东亚冬季风各主要特征及其年际变化、同时包含西伯利亚高压、东亚大槽和纬向风经向切变信息的强度指数（EAWMII）。分析表明，这个新指数EAWMII能够很好地反映东亚冬季风在20世纪80年代中期的减弱信号，并且与大气环流场以及东亚冬季表面温度的变化均显著相关，能够在很大程度上表征东亚冬季风的综合特征。此外，EAWMII与北极涛动（Arctic Oscillation, 简称AO）指数、北太平洋涛动（North Pacific Oscillation, 简称NPO）指数和Niño3.4指数相关显著。分析还表明AO和NPO影响东亚冬季气候的区域有所不同：AO主要影响欧亚大陆中、高纬、我国东北以及日本北部等地区，NPO则主要影响华南、华东、朝鲜、韩国以及日本中南部及其附近海域。并且，AO很可能可以通过影响NPO进而影响东亚冬季风。</p> </div>

In this study, the water vapor sources for the precipitation processes in southeastern China (SECN) during 1981–2010 were investigated using atmospheric reanalysis data. We also studied the factors influencing the summer atmospheric moisture over SECN. These two issues are all closely related to the climate signals recorded in stalagmites recovered from caves in SECN. Result supports that the atmospheric water vapor over SECN during the whole summer time is primarily transported from the Indian Ocean. However, the vertically integrated water vapor content throughout the year in SECN has two main sources: the Indian Ocean and the tropical western Pacific. In addition, the water vapor transport for the precipitation processes in SECN has complex vertical structure. At approximately 700 hPa to 500 hPa, part of the water vapor for the precipitation in SECN comes from the Arab-Caspian region. Finally, the water vapor content over SECN is regulated primarily by both the Indian and East Asian monsoons. Further analysis indicated that the variability of the East Asian summer monsoon is substantially regulated by the western Pacific subtropical high, the Eurasia–Atlantic thermal conditions, as well as the large-scale Eurasia-Atlantic atmospheric circulation. Therefore, the SECN Cave proxies can record the signals from faraway middle and high latitude Eurasia-Atlantic climate, besides the regional East Asian monsoon and remote Indian monsoon.</div>

Recently, frequent snowstorms have occurred during the winter, causing large economic losses and attracting wide attention. In particular, these snowstorms have raised an important scientific question: under the scenarios of future global warming, will winter precipitation in China increase significantly and produce more snow in the north? Using the Coupled Model Intercomparison Project phase 3 (CMIP 3) models’ projections under the SRES A1B scenario, we generated a possible future Arctic condition, the summer (September) ‘ice-free Arctic’ condition, and then used the corresponding monthly sea surface temperature (SST) values and the set of CO2 concentrations to drive an AGCM model to simulate the resulting East Asian climate change.<br /> The experimental results show that during the boreal winter (DJF), the global surface air temperature would increase significantly under this scenario and produce substantial warming in the Arctic regions and in the high latitudes of Asia and North America. The Siberian High, Aleutian Low and East Asian winter monsoon would all be weakened. However, due to the increased transport of water vapor to China from the north, the winter precipitation would increase from south to north. In addition, the significant increase in the winter temperature might cause fewer cold surges to occur.</div>

使用全球版本的迈阿密等密度海洋环流模式对2011年3月日本福岛核电站泄漏在海洋中的传输以及扩散进行了数值模拟。数值模式中核废料（示踪物）排放情景采取等通量连续排放，排放时间从3月25日开始，分别持续20d以及1a，两种情形分别积分20a。为了减少海洋环流年际变化带来的数值模拟的的不确定性，20a的模式积分分别用2010年、1991-2011年、1971-1991年以及1951-1971年4个不同时段的NCEP/NCAR逐日再分析资料作为大气强迫场，因此每种排放情形包含４个数值试验。模拟结果的分析表明，不同核废料排放情景及其在不同时段大气资料对海洋模式的驱动下，模拟的示踪物总体的传输扩散路径（包括表层以及次表层）、传输速率以及垂直扩展的范围没有显著的差异。集合平均数值模拟的结果显示：在两种排放情景下，日本福岛核泄漏在海洋的传输路径受北太平洋副热带涡旋洋流系统主导，其传输路径首先主要向东，到达东太平洋后，再向南向西扩散至西太平洋，可能在10-15a左右影响到我国东部沿海海域，且海洋次表层的传输信号比表层信号早5a左右。通过进一步分析模式积分过程中最大示踪物浓度随时间变化发现，在积分第20a（2031年3月），海洋表层和次表层浓度的最高值分别只有模式积分第一年浓度的0.1% 和1%。在积分的20a里，排放的核废料主要滞留在北太平洋海域（超过86% ±1.5%的核废料在积分结束时，滞留在北太平洋），而在积分的前10a（2021年之前），几乎所有的核废料滞留在北太平洋；在核废料的垂直分布上，主要集中在海洋表层至600m 的深度，在积分的20a时间里，没有核废料信号扩散至1000m 以下的深度。数值模拟的结果也表明核废料浓度减弱的强度以及演变的时间特征主要受洋流系统的影响，与排放源的排放时间长短关系不大。值得指出的是，更加准确地评估一个真实的核泄漏事故对海洋环境所造成的可能影响，还需要考虑大气中的放射性物质的沉降以及海洋生态对核物质的响应。</div>

A new seasonal prediction model for annual tropical storm numbers (ATSNs) over the western North Pacific was developed using the preceding January-February (JF) and April-May (AM) grid-point data at a resolution of 2.5°×2:5°. The JF and AM mean precipitation and the AM mean 500-hPa geopotential height in the Northern Hemisphere, together with the JF mean 500-hPa geopotential height in the Southern Hemisphere, were employed to compose the ATSN forecast model via the stepwise multiple linear regression technique. All JF and AM mean data were confined to the Eastern Hemisphere. We established two empirical prediction models for ATSN using the ERA40 reanalysis and NCEP reanalysis datasets, respectively, together with the observed precipitation. The performance of the models was verified by cross-validation. Anomaly correlation coefficients (ACC) at 0.78 and 0.74 were obtained via comparison of the retrospective predictions of the two models and the observed ATSNs from 1979 to 2002. The multiyear mean absolute prediction errors were 3.0 and 3.2 for the two models respectively, or roughly 10% of the average ATSN. In practice, the final prediction was made by averaging the ATSN predictions of the two models. This resulted in a higher score, with ACC being further increased to 0.88, and the mean absolute error reduced to 1.92, or 6.13% of the average ATSN.</div>

FOAM 也能较好地模拟出北大西洋、北太平洋以及南美西海岸的显著增暖, 但模拟的次极地北大西洋和赤道太平洋SST 的变化与重建数据仍有差别. 上述重建与模拟的差异是由古气候数据重建的不确定性、上新世中期模拟的困难以及模式本身的不完善共同造成的.</div> </td> </tr> <tr height="20"> <td> </td> <td> </td> </tr> </tbody> </table>

Yue, X., Liao, H., Wang, H. J., Li, S. L., and Tang, J. P, 2011: Role of sea surface temperature responses in simulation of the climatic effect of mineral dust aerosol,. Atmospheric Chemistry and Physics, 11, 6049-6062
Mineral dust aerosol can be transported over the nearby oceans and influence the energy balance at the sea surface. The role of dust-induced sea surface temperature (SST) responses in simulations of the climatic effect of dust is examined by using a general circulation model with online simulation of mineral dust and a coupled mixed-layer ocean model. Both the longwave and shortwave radiative effects of mineral dust aerosol are considered in climate simulations. The SST responses are found to be very influential on simulated dust-induced climate change, especially when climate simulations consider the two-way dust-climate coupling to account for the feedbacks. With prescribed SSTs and dust concentrations, we obtain an increase of 0.02 K in the global and annual mean surface air temperature (SAT) in response to dust radiative effects. In contrast, when SSTs are allowed to respond to radiative forcing of dust in the presence of the dust cycle-climate interactions, we obtain a global and annual mean cooling of 0.09 K in SAT by dust. The extra cooling simulated with the SST responses can be attributed to the following two factors: (1) The negative net radiative forcing of dust at the surface reduces SST, which decreases latent heat fluxes and upward transport of water vapor, resulting in less warming in the atmosphere; (2) The positive feedback between SST responses and dust cycle. The dust-induced reductions in SST lead to reductions in precipitation (or wet deposition of dust) and hence increase the global burden of small dust particles. These small particles have strong scattering effects, which enhance the dust cooling at the surface and further reduce SSTs.</div>
Yue, X., Wang, H. J., Liao, H., and Jiang, D. B, 2011: Simulation of the direct radiative effect of mineral dust aerosol on the climate at the Last Glacial Maximum. Journal of Climate, 24, 843-858
The climatic responses to the direct radiative effect of dust aerosol at the Last Glacial Maximum (LGM) are examined using a general circulation model with online simulation of dust. The predicted global dust emission at the LGM is 2.3 times as large as the present-day value, which is the combined effect of the expansion of dust sources and the favorable meteorological parameters (MPs, such as the strong surface wind and the low air humidity) under the LGM climate. Simulated global dust emission is 1966 Tg yr-1 with present-day dust sources and MPs, 2820 Tg yr-1 with LGM dust sources and current MPs, 2599 Tg yr-1 with present-day dust sources and LGM MPs, and 4579 Tg yr-1 with LGM sources and MPs. The simulated percentage increases of dust concentrations are the largest at high latitudes in both hemispheres, which are consistent with the deposition data from geological records. The LGM dust is estimated to exert global annual mean shortwave (SW) and longwave (LW) radiative forcings (RF) of, respectively, -4.69 W m-2 and +1.70 W m-2 at the surface, and -0.58 W m-2 and + 0.68 W m-2 at the top of the atmosphere. On a global and annual mean basis, surface air temperature (SAT) is predicted to be reduced by 0.18 K and precipitation is reduced by 0.06 mm day-1, as a result of the net (SW and LW) radiative effect of dust at the LGM. Two sensitivity studies are performed to identify the uncertainties in simulated climatic effect of LGM dust that arise from the assumed LW and/or SW absorption by dust: (1) in the absence of dust LW radiative effect, the LGM global and annual mean SAT is predicted to be further reduced by 0.19 K; and (2) when the single scattering albedo of the Saharan dust at 0.55 μm is increased from 0.89 to 0.98 in the LGM climate simulation, the LGM dust-induced annual and global mean surface cooling increases from 0.18 K to 0.63 K even with both SW and LW radiative effects of dust. In these two sensitivity studies, the LGM dust is predicted to induce an average cooling of, respectively, 0.42 and 0.72 K in SAT over the tropical oceans.</div>
Wang Huijun, Yu Entao, Yang Song, 2011: An exceptionally heavy snowfall in Northeast China: large-scale circulation anomalies and hindcast of the NCAR WRF model. Meteorol. Atmos. Phys, 113, 11-25
In Northeast China (NEC), snowfalls usually occur during winter and early spring, from mid-October to late March, and strong snowfalls rarely occur in middle spring. During 12–13 April 2010, an exceptionally strong snowfall occurred in NEC, with 26.8 mm of accumulated water-equivalent snow over Harbin, the capital of the most eastern province in NEC. In this study, the major features of the snowfall and associated large-scale circulation and the predictability of the snowfall are analyzed using both observations and models. The Siberia High intensiﬁed and shifted southeastward from 10 days before the snowfall, resulting in intensifying the low-pressure system over NEC and strengthening the East Asian Trough during 12–13 April. Therefore, large convergence of water vapor and strong rising motion appeared over eastern NEC, resulting in heavy snowfall. Hindcast experiments were carried out using the NCAR Weather Research and Forecasting (WRF) model in a two-way nesting approach, forced by NCEP Global Forecast System data sets. Many observed features including the large-scale and regional circulation anomalies and snowfall amount can be reproduced reasonably well, suggesting the feasibility of the WRF model in forecasting extreme weather events over NEC. A quantitative analysis also shows that the nested NEC domain simulation is even better than mother domain simulation in simulating the snowfall amount and spatial distribution, and that both simulations are more skillful than the NCEP Global Forecast System output. The forecast result from the nested forecast system is very promising for an operational purpose.</div>
WANG Huijun and ZHANG Ying, 2010: Model Projections of East Asia Summer Climate under the ‘Free Arctic’ Scenario. ATMOSPHERIC AND OCEANIC SCIENCE LETTERS, 3(3), 176-180
This paper addresses the ‘ice-free Arctic’ issue under the future global warming scenario. Four coupled climate models used in the third phase of the Coupled Model Intercomparison Project (CMIP3) were selected to project summer climate conditions over East Asia once the Arctic becomes ice-free. The models project that an ice-free Arctic summer will begin in the 2060s under the SRESA1B (according to IPCC Special Reports on Emissions Scenarios) simulations. Our results show that the East Asian summer monsoons will tend to be stronger and that the water vapor transport to central northern China will be strengthened, leading to increased summer precipitation in central northern China. The models also project an intensified Antarctic Oscillation, a condition which favors increased precipitation in South China’s Yangtze River Valley. The overall precipitation in Northwest China is projected to increase under ice-free Arctic summer conditions.</div>

We examine equilibrium climate responses to the shortwave and/or longwave direct radiative effect of mineral dust aerosol using the Global transport Model of Dust (GMOD) embedded within a general circulation model (GCM). The presence of mineral dust aerosol in the atmosphere is estimated to exert global mean shortwave and longwave radiative forcings (RF) of -0.25 W m-2 and +0.27 W m-2, respectively, at the top of the atmosphere (TOA) and -1.95 W m-2 and +0.61 W m-2 at the surface. Climatic effect of dust is simulated using two different approaches. In the first approach, monthly mean fields of dust simulated a priori are used in the radiative transfer module of the GCM to drive climate change, with levels of dust fixed during the climate integration (denoted as simulation FIXDST). In the second approach, dust aerosol interacts online with meteorology through the dust cycle and its direct radiative effect (denoted as simulation CPLD). With both longwave and shortwave RF of dust, predicted changes in global and annual mean surface air temperature and air temperature at 200 hPa are zero and +0.12 K, respectively, in FIXDST, and -0.06 K and +0.05 K in the CPLD simulation. The stronger cooling in CPLD than in FIXDST is a result of a 13% higher dust burden in CPLD with dust-climate interactions. Although dust longwave radiative effect is predicted to offset a large portion of its shortwave effect on a global and annual mean basis, dust shortwave effect dominates during the daytime, and the longwave effect prevails at night, which is found to be very important for predictions of temperature. For example, over the Sahara Desert, the changes in annual mean, annual mean daytime, and annual mean nighttime surface air temperature are predicted to be +0.32 K, -0.11 K, and +0.68 K, respectively, in the FIXDST simulation. The longwave and shortwave radiative effects of dust are predicted to have different impacts on the dust cycle in CPLD simulation; the solar radiative effect reduces dust emissions by increasing surface humidity and by reducing surface wind speed, while the thermal effect increases dust uplift through opposite changes in the meteorological parameters.</div>
Jianqi Sun, Huijun Wang and Wei Yuan,, 2010: Linkage of the Boreal Spring Antarctic Oscillation to the West African Summer Monsoon. Journal of the Meteorological Society of Japan, 88, 15-28
The relationship between the boreal spring (or the austral autumn) Antarctic Oscillation (AAO) (March– April) and the West African summer monsoon (WASM) (June–September) is analyzed based on NCEP/NCAR reanalysis data. The results show that the linkage of the boreal spring AAO to the WASM exhibits decadal-scale variations: a strong connection between the two appears over the period 1985–2006 and a weak connection over the period 1970–1984. Further analysis indicates that such an unstable relationship between the two results from the modulation by ENSO events to a large extent.
A possible mechanism for the impacts of the boreal spring AAO on the WASM is also discussed. The variability of the boreal spring tropical South Atlantic sea surface temperature (SST) appears to serve as a bridge linking these two systems. The boreal spring AAO produces an anomalous SST over the tropical South Atlantic by exciting an equatorward Rossby wave train over the western Southern Hemisphere (SH). This AAO-related SST anomaly modulates the meridional gradient of moist static energy (MSE) between the Sahel and the Guinea-tropical Atlantic region in the boreal spring. The MSE gradient is of paramount importance for the changes from spring to summer in the West African monsoon because its relaxation along the seasonal cycle is linked to the northward excursion of the WASM system into the African continent. Therefore, an anomalous AAO-related MSE gradient can lead to anomalous Sahel rainfall in the early summer. When this rainfall occurs over the Sahel, the local positive soil moisture-rainfall feedback plays a crucial role in sustaining and prolonging this rainfall anomaly throughout the whole summer.

This study documents the decadal changes of the summer precipitation in East China, with increased rainfall in the Huang-Huai River region (HR) and decreased in the Yangtze River region (YR) during 2000–2008 in comparison to 1979–1999. The main features of the atmospheric circulation related to the increased precipitation in the HR are the strengthened ascending motion and slightly increased air humidity, which is partly due to the weakened moisture transport out of the HR to the western tropical Pacific (associated with the weakened westerly over East Asia and the warming center over the Lake Baikal). The rainfall decrease in the YR is related to the weakened ascending motion and reduced water vapor content, which is mainly related to the weakened southwesterly moisture flux into the YR (associated with the eastward recession of the Western Pacific Subtropical High). The global sea surface temperature (SST) also shows significant changes during 2000–2008 relative to 1979–1999. The shift of the Pacific decadal oscillation (PDO) to a negative phase probably induces the warming over the Lake Baikal and the weakened westerly jet through the air-sea interaction in the Pacific, and thus changes the summer precipitation pattern in East China. Numerical experiments using an atmospheric general circulation model, with prescribed all-Pacific SST anomalies of 2000–2008 relative to 1979–1999, also lend support to the PDO’s contribution to the warming over the Lake Baikal and the weakened westerlies over East China.</div> </td> </tr> <tr height="20"> <td> </td> <td> </td> </tr> </tbody> </table>

WANG Huijun and QIAN Zhuolei, 2010: A potential high-score Scheme for the seasonal prediction of Atlantic storm activity. ATMOSPHERIC AND OCEANIC SCIENCE LETTERS, 3(2), 116−119
A new empirical approach for the seasonal prediction of annual Atlantic tropical storm number (ATSN) was developed using precipitation and 500 hPa geopotential height data from the preceding January−February and April−May. The 2.5°×2.5° resolution reanalysis data from both the US National Center for Environmental Prediction/the National Center for Atmospheric Research (NCEP/NCAR) and the European Center for Medium-Range Weather Forecasting (ECMWF) were applied. The model was cross-validated using data from 1979−2002. The ATSN predictions from the two reanalysis models were correlated with the observations with the anomaly correlation coefficients (ACC) of 0.79 (NCEP/NCAR) and 0.78 (ECMWF) and the multi-year mean absolute prediction errors (MAE) of 1.85 and 1.76, respectively. When the predictions of the two models were averaged, the ACC increased to 0.90 and the MAE decreased to 1.18, an exceptionally high score. Therefore, this new empirical approach has the potential to improve the operational prediction of the annual tropical Atlantic storm frequency.</div> </div>
Xianmei Lang and Huijun Wang, 2010: Improving Extraseasonal Summer Rainfall Prediction by Merging Information from GCMs and Observations. WEATHER AND FORECASTING, 25, 1263-1274
A new prediction approach for summer (June–August) rainfall in China was designed by considering both preceding observations and numerically predicted summer rainfall through a multivariate linear regression analysis. First, correlation analyses revealed close relationships between summer rainfall in parts of China with the Antarctic Oscillation (AAO), the Arctic Oscillation (AO), and sea surface temperatures (SSTs) in the preceding winter (December–February). The Huang-Huai Valley, two subregions of the Jiang-Huai Valley, the southern Yangtze River, south China, and southeastern Xinjiang were then chosen as targets for their regional climate characteristics. Following this, an extraseasonal (one season in advance) regression prediction model for regionally averaged summer rainfall was constructed by using these three climate factors and a 3-month leadtime forecast of summer rainfall, undertaken by an atmospheric general circulation model (GCM) forced by observed SSTs, as predictors region by region. To improve the accuracy of prediction, the systematic error between the original regression model’s results and its observational counterparts, averaged for the last 10 yr,was corrected. Using this new approach, real-time prediction experiments and cross-validation analyses were performed for the periods 2002–07 and 1982–2007, respectively. It was found that the new prediction approach was more skillful than the original or corrected GCM prediction alone in terms of sign, magnitude, and interannual variability of regionally averaged summer rainfall anomalies in all regions. The preceding observations were the major source of the prediction skill of summer rainfall in each region, and the GCM predictions added additional prediction skill in thewestern Jiang-HuaiValley and southeastern Xinjiang, in both of which the GCM prediction was used as a predictor. <p> </p> </div>

The statistical spatial‐temporal features of the intense snowfall event (ISE) in China are investigated over the period of 1962–2000. The results indicate that eastern China, northern Xinjiang, the eastern Tibetan plateau, and northeastern China are four key regions for the ISE, with more frequency and strong variability. Annual cycle analysis shows the ISE exhibits a unimodal distribution with maximum frequency at winter months for eastern China, a bimodal distribution with maximum frequency at early winter and spring months for northern Xinjiang and northeastern China, and a bimodal distribution with maximum frequency at autumn and spring months for the eastern Tibetan plateau. Linear trend analysis indicates that in the last 39 years, the ISE exhibits a decreasing trend for eastern China and an increasing trend for northern Xinjiang and the eastern Tibetan plateau. The linear trend of the ISE is weak over northeastern China. Based on the simulations of the most recent and comprehensive climate models in the 20th century run, the performance of the current climate models in simulating the Chinese ISE is investigated. The results indicate that, of the 20 models, there are four models that can reasonably reproduce the spatial‐temporal features of the Chinese ISE. Based on these four models’ simulation for the 21st century under A1B and A2 scenarios, the future variability of the Chinese ISE is projected. It is found that global warming will cause the ISE frequency over southern China to decrease, while the ISE over northern China will initially increase and then decrease.

The Tropical Cyclone Genesis Potential Index (GPI) was employed to investigate possible impacts of global warming on tropical cyclone genesis over the western North Paci¯c (WNP). The outputs of 20th century climate simulation by eighteen GCMs were used to evaluate the models' ability to reproduce tropical cyclone genesis via the GPI. The GCMs were found in general to reasonably reproduce the observed spatial distribution of genesis. Some of the models also showed ability in capturing observed temporal variation. Based on the evaluation, the models (CGCM3.1-T47 and IPSL-CM4) found to perform best when reproducing both spatial and temporal features were chosen to project future GPI. Results show that both of these models project an upward trend of the GPI under the SRES A2 scenario, however the rate of increase differs between them.</div>

Direct climate responses to dust shortwave and longwave radiative forcing (RF) are studied using the NCAR Community Atmosphere Model Version 3 (CAM3). The simulated RF at the top of the atmosphere (TOA) is ¡0.45 W m¡2 in the solar spectrum and +0.09 W m¡2 in the thermal spectrum on a global average. The magnitude of surface RF is larger than the TOA forcing, with global mean shortwave forcing of ¡1.76 W m¡2 and longwave forcing of +0.31 W m¡2. As a result, dust aerosol causes the absorption of 1.1 W m¡2 in the atmosphere. The RF of dust aerosol is predicted to lead to a surface cooling of 0.5 K over the Sahara Desert and Arabian Peninsula. In the meantime, the upper troposphere is predicted to become warmer because of the absorption by dust. These changes in temperature lead to a more stable atmosphere, which results in increases in surface humidity. The upward sensible and latent heat °uxes at the surface are reduced, largely balancing the surface energy loss caused by the backscattering and absorption of dust aerosol. Precipitation is predicted to decrease moderately on a global scale.</div> </td> </tr> <tr height="20"> <td> </td> <td> </td> </tr> </tbody> </table>
ZHU Yali,WANG Huijun, 2010: The Relationship between the Aleutian Low and the Australian Summer Monsoon at Interannual Time Scales. Advances in Atmospheric Sciences, 27(1), 177-184
The relationship between the boreal winter (December, January, February) Aleutian Low (AL) and the simultaneous Australian summer monsoon (ASM) is explored in this study. A significant correlation is found between the North Pacific index (NPI) and ASM index, the bulk of which is attributed to the significant correlation after late 1970s. Significant differences in precipitation and outgoing long-wave radiation between typical negative and positive NPI years appear over the ASM area. A regression analysis of the circulation pattern against the NPI during the three months is performed separately. We propose that the NPI is related with the ASM circulation possibly through the changes in the upper level westerly jet. In a typical negative NPI (strong Aleutian Low) year, the jet is greatly reinforced and the anomalous anticyclonic circulation to the south is thus excited, from which the easterly wind anomalies °owing into the ASM region emanate. Further, strong sinking motion over the northern entrance region of the jet is enhanced, and the local Hadley circulation anomaly between the ASM region and the coast of East Asia is strengthened. In this way, anomalous upward motion over the ASM area can thus be strengthened, and the convective activity intensified. Then the monsoon rainfall over ASM area is increased. An \asymmetric" connection between AL and the monsoon is found in this study.</div>
ANG Jun and WANG Huijun, 2010: The Relationship between Total Ozone and Local Climate at Kunming Using Dobson and TOMS Data. ATMOSPHERIC AND OCEANIC SCIENCE LETTERS, 3(4), 207-212
This paper uses Dobson spectrometer total ozone data, Total Ozone Mapping Spectrometer (TOMS) data and radiosonde reports from Kunming, which is located in southwest China, from 1980 to 2008 to analyze the total ozone-climate relationship. The total ozone decadal long-term trend and abrupt change were studied using enhanced Dobson data whose missing data were amended by the TOMS data. Stepwise linear regression was used for the selection of the key factors that influence total ozone, including temperatures, geopotential heights, depressions of the dew point, wind velocities, and total solar radiation. The relationship between the selected factors and total ozone was analyzed using the methods of stepwise regression and partial least squares regression(PLSR). Results showed that although the PLSR method was slightly better and more reasonable to study the relationship than stepwise regression, while the two regression results were only slightly different. It was also suggested that local climate, especially local circulation and temperature, were important for the variations in total ozone, and the local climate could almost linearly explain 80% of the variance of total ozone. The relationship also indicated that the abrupt change of total ozone in the year 1994 may be related to abrupt local climate change.</div>

In the present study, datasets derived from twelve coupled ocean–atmosphere general circulation models (OAGCMs) in the Paleoclimate Modelling Intercomparison Project phase two were used to analyze the East Asian summer climate during the mid-Holocene (about 6000 calendar years ago). On the whole, the OAGCMs reproduced warmer and wetter summer climate conditions in East Asia during the mid-Holocene. The multimodel ensemble showed that in East Asia, the regionally-averaged summer surface air temperature (SAT) increased by 0.89 °C, summer precipitation was 5.8% higher, and an obviously strengthened southerly wind corresponded to a strong summer monsoon in the mid-Holocene when compared to preindustrial levels. The data-model comparison in China reveals a good agreement between the OAGCMs' results and the reconstructed changes in the summer SAT in East China during the mid-Holocene. In North China, the simulated SAT anomalies are 0.5 °C lower overall than reconstruction. In contrast, the OAGCMs fail to capture the strongest warming in the southern Qinghai–Tibetan Plateau. On the other hand, the simulated precipitation agrees well with proxy data except for in the central parts of China, where the simulated summer precipitation disagrees in sign with reconstruction. In addition, there is a large spread among the simulations, particularly over and around the Qinghai–Tibetan Plateau, and inter-model discrepancies arelarger for precipitation than for SAT as a whole.</div> </td> </tr> <tr height="20"> <td> </td> <td> </td> </tr> </tbody> </table>
Huijun Wang and Ke Fan, 2009: A New Scheme for Improving the Seasonal Prediction of Summer Precipitation Anomalies. Weather and Forecasting, 24, 548–554
A new scheme is developed to improve the seasonal prediction of summer precipitation in the East Asian and western Pacific region. The scheme is applied to the Development of a European Multimodel Ensemble System for Seasonal to Interannual Prediction (DEMETER) results. The new scheme is designed to consider both model predictions and observed spatial patterns of historical ‘‘analog years.’’ In this paper, the anomaly pattern correlation coefficient (ACC) between the prediction and the observation, as well as the root-meansquare error, is used to measure the prediction skill. For the prediction of summer precipitation in East Asia and the western Pacific (0–40N, 80–130E), the prediction skill for the six model ensemble hindcasts for the years of 1979–2001 was increased to 0.22 by using the new scheme from0.12 for the original scheme. Allmodels were initiated in May and were composed of nine member predictions, and all showed improvement when applying the newscheme.The skill levelsof the predictions for the sixmodels increased from0.08, 0.08, 0.01, 0.14, -0.07, and 0.07 for the original scheme to 0.11, 0.14, 0.10, 0.22, 0.04, and 0.13, respectively, for the new scheme. <p> </p> </div>
Ke Fan and Huijun Wang, 2009: A New Approach to Forecasting Typhoon Frequency over the Western North Pacific. WEATHER AND FORECASTING, 24, 74-986
This paper presents a new approach for forecasting the typhoon frequency of the western North Pacific (WNP). The year-to-year increase or decrease in typhoon frequency is first forecasted to yield a net typhoon frequency prediction. Five key predictors for the year-to-year increment in the number of typhoons in the WNP have been identified, and a forecast model is established using a multilinear regression method based on data taken from 1965 to 2001. Using the forecast model, a hindcast of the typhoon frequency of the WNP during 2002–07 is made. The model exhibited a reasonably close fit for the period 1965–2007, including the larger anomalies in 1997 and 1998. It also accounted for the smaller variability of the typhoon frequency of the WNP during the validation period 2002–07 with an average root-mean-square error (RMSE) of 1.3 (2.85) during 2002–07 (1965–2001).The cross-validation test of the prediction model shows that the new approach and the prediction model demonstrate better prediction skill when compared to the models established based on typhoon frequency rather than the typhoon frequency increment. Thus, this new approach has the potential to improve the operational forecasting skill for typhoon frequency in the WNP.</div>
Wang Huijun, and Jianqi Sun, 2009: Variability of Northeast China River Break-up Date. Advances in Atmospheric Sciences, 26(4), 701-706
This paper investigates the variability of the break-up dates of the rivers in Northeast China from their icebound states for the period of 1957–2005 and explores some potential explanatory mechanisms. Results show that the break-up of the two major rivers (the Heilongjiang River and Songhuajiang River)was about four days earlier, and their freeze-up was about 4–7 days delayed, during 1989–2005 as compared to 1971–1987. This interdecadal variation is evidently associated with the warming trend over the past 50 years. In addition, the break-up and freeze-up dates have large interannual variability, with a standard deviation of about 10–15 days. The break-up date is primarily determined by the January–February–March mean surface air temperature over the Siberian-Northeast China region via changes in the melting rate, ice thickness, and snow cover over the ice cover. The interannual variability of the break-up date is also significantly connected with the Northern Annular Mode (NAM), with a correlation coefficient of 0.35–0.55 based on the data from four stations along the two rivers. This relationship is attributed to the fact that the NAM can modulate the East Asian winter monsoon circulation and Siberian-Northeast China surface air temperature in January–February–March.</div>

Jianqi Sun, Huijun Wang and Wei Yuan, 2009: Role of the tropical Atlantic sea surface temperature in the decadal change of the summer North Atlantic Oscillation. JOURNAL OF GEOPHYSICAL RESEARCH, 114, D20110, doi:10.1029/2009JD012395
Recent observational studies have shown that the southern center of the summer North Atlantic Oscillation (SNAO) shifted eastward after the late 1970s. In this study, this phenomenon and its causes are further explored. It is found that the decadal spatial shift of the SNAO southern center is related to the decadal variability of the tropical Atlantic sea surface temperature (TASST). In the past half century, the TASST experienced an abrupt change around the late 1970s, with a rapid warming in the recent 2 decades. Thus in the period after the late 1970s when the TASST is relatively warmer, the TASST released more energy into the atmosphere, then stimulated strong convection over the tropical Atlantic, and further excited anomalous wave-like patterns. This strengthened the circulation in the region of the Mediterranean Sea, namely the east part of the SNAO southern center, consequently leading to an eastward shift of the SNAO southern center. Meanwhile, in the period before the late 1970s when the TASST is relatively cooler, the TASST released less energy into the atmosphere, so its impact on the overlying atmosphere was significantly weakened and confined to the lower-level atmosphere of the tropical Atlantic. Thus the TASST possibly did not influence the variability of the SNAO southern center, and the SNAO pattern exhibited a traditional distribution with two centers over the North Atlantic.</div>

The connection between the boreal spring Hadley circulation (HC) and variability of the following summer east Asian atmospheric circulations and precipitation in the Yangtze River valley is investigated through an analysis of the observed data in this study. It is found that there is a significantly positive correlation between HC and the summer rainfall in the Yangtze River valley. This relationship is well supported by the changes of atmospheric general circulation backgrounds and water vapor conditions related to the variation of the preceding boreal spring HC. The summer situations of strengthened western Pacific subtropical high (WPSH), intensified South Asian high (SAH), southward located east Asian jet (EAJ) and enhanced water vapor corresponding to strong spring HC provide favorable conditions for increasing the precipitation in the Yangtze River valley and vice versa. The possible mechanism how the boreal spring HC affects summer atmospheric circulations is identified preliminarily in the study. Results show that sea surface temperature (SST) anomalies in the Indian Ocean and South China Sea may play an important role in linking the spring HC and summer atmospheric circulations. Spring HC may evoke SST anomalies in the Indian Ocean and South China Sea, which can persist from spring to summer and in turn give rise to anomalous east Asian summer monsoon. As a result, summer rainfall in the Yangtze River valley may be influenced.

Wang Huijun, 2006: Linkage Between the Northeast Mongolian Precipitation and the Northern Hemisphere Zonal Circulation. Advances in Atmospheric Sciences, 23(5), 659–664
The long-term relationship between the tree-ring-reconstructed annual precipitation in northeastern Mongolia (PRM) and the Northern Hemisphere Zonal Circulation (NHZC)§defined as the normalized zonal mean sea-level pressure at 60N in May-June-July, is examined in this study. A significant correlation coefficient (0.31) was found between the NHZC indices and PRM based on the dataset for the period of 1872–1995. The mechanisms responsible for the relationship are discussed through analyses of the atmospheric general circulation variability associated with NHZC. It follows that NHZC-related atmospheric circulation variability provides an anomalous southeast flow from the ocean to Northeast Mongolia (northwest flow from Northeast Mongolia to the ocean) in the middle and low troposphere in positive (negative) phase of NHZC, resulting in more (less) water vapor transport to the target region and more (less) precipitation in Northeast Mongolia.</div>

Geological research has illustrated the transition of palaeoenvironmental patterns by the earliest Miocene from a planetary-wind-dominant type to a monsoon-dominant type, indicating that the East Asian monsoon became markedly intensified and played a leading role in the East Asian climate. From a modeling point of view, the pioneering research using the reduced number of scenarios had demonstrated that both the Tibetan Plateau uplift and the Paratethys Sea retreat were important for understanding the Asian monsoon evolution. However, the sensitivity of the Paratethys retreat to the East Asian climate still needs further studies based on the more detailed scenarios. Thirty numerical experiments under the six Paratethys Sea and the five Tibetan Plateau conditions illustrate the shifts from zonal climate to the monsoon climate in East Asia. The results confirm again that both the Paratethys retreat and the Tibetan plateau uplift play important roles in the formation of the monsoon-dominant environmental pattern, and show that the Paratethys retreat can strengthen the East Asian monsoon and greatly increase humidity and aridity respectively in the monsoon areas and Northwest China, which is similar to the impact of the Tibetan Plateau uplift on the East Asian climate. Furthermore, the fact that the Paratethys Sea retreats to the Turan Plate is found to be the key criterion for the palaeoenvironmental patterns' transition in China. The shrinkage of Paratethys Sea leads to the reconstructions of the pressure system and the atmospheric circulations, which result in the variations of precipitation and the transition of palaeoenvironmental patterns. <p> </p> </div>
WANG Huijun, 2005: The Circum-Pacific Teleconnection Pattern in Meridional Wind in the High Troposphere. Advances in Atmospheric Sciences, 22(3), 463–466
The Circum-Pacific Teleconnection Pattern (CPTP) is revealed in the meridional wind in the high troposphere via an emprirical orthogonal function (EOF) and correlation analysis on NCEP/NCAR reanalysis data. The CPTP is found to be composed of the North Pacific–North American teleconnection pattern (PNA), the South Pacific–South American teleconnection pattern (PSA), and the teleconnection patterns over the tropical western Pacific and the tropical eastern Pacific (or, Central America, or, tropical Atlantic). There is substantial interannual variability of the CPTP and a typical CPTP can be detected in some years. It is speculated that the zonal wind anomalies over the equatorial region in the western and eastern sides of the Pacific may play a role in linking the two hemispheres. The anomalous convection activities in the Tropics are plausible triggering factors for the zonal wind anomalies that are responsible for the composition of the CPTP.</div>

It follows that AAO-related variability of convergence and convection over the tropical western Pacific can exert impact on the circulation condition and precipitation in north China (actually, the precipitation in the Yangtze River Valley as well) through atmospheric teleconnection known as the East Asia-Pacific (or Pacific–Japan) teleconnection wave pattern. There is also an AAO-connected wave train in the vorticity field at high troposphere over Eurasia, providing an anti-cyclonic circulation in central-north China favorable to the decline of precipitation in positive phase of AAO.</div> </td> </tr> <tr height="20"> <td> </td> <td> </td> </tr> </tbody> </table>

文中研究了年代际时间尺度上冬季(11~3月)北极涛动与太平洋年代际振荡之间的关系. 结果发现, 北极涛动对于太平洋年代际振荡的变化起着重要的作用. 当北极涛动超前太平洋年代际振荡7~8年的时候, 两者的相关关系最好, 相关系数为0.77. 这种年代际时间尺度上的超前性对太平洋年代际振荡的变化有着很好的预测意义. 回归分析和超前滞后相关的结果表明北极涛动与太平洋年代际振荡耦合的关键可能在于阿留申低压: 强的北极涛动导致阿留申低压加深, 进而通过北半球中纬度的海气相互作用影响到太平洋年代际振荡, 反之亦然。

A new climate simulation for the middle Pliocene (ca. 3 Ma BP) is performed by a global grid-point atmospheric general circulation model developed at the Institute of Atmospheric Physics (IAP AGCM) with boundary conditions provided by the U. S. Geological Survey’s Pliocene Research, Interpretations, and Synoptic Mapping (PRISM) group. It follows that warmer and slightly wetter conditions dominated at the middle Pliocene with a globally annual mean surface temperature increase of 2.60C, and an increase in precipitation of 4.0% relative to today. At the middle Pliocene, globally annual terrestrial warming was 1.86C, with stronger warming toward high latitudes. Annual precipitation enhanced notably at high latitudes, with the augment reaching 33.5% (32.5%) of the present value at 60–90N (60–90S). On the contrary, drier conditions were registered over most parts at 0–30N, especially in much of East Asia and the northern tropical Pacific. In addition, both boreal summer and winter monsoon significantly decreased in East Asia at the middle Pliocene. It is indicated that the IAPAGCM simulation is generally consistent with the results from other atmospheric models and agrees well with available paleoclimatic reconstructions in East Asia. Additionally, it is further revealed that the PRISM warmer sea surface temperature and reduced sea ice extent are main factors determining the middle Pliocene climate. The simulated climatic responses arising from the PRISM reconstructed vegetation and continental ice sheet cannot be neglected on a regional scale at mid to high latitudes (like over Greenland and the Qinghai-Tibetan Plateau, and around the circum-Antarctic) but have little influence on global climate.</div>
Fan Ke, and Wang Hui-Jun, 2004: Antarctic oscillation and the dust weather frequency in North China. Geophys. Res. Lett, 31, L10201, doi:10.1029/2004GL019465
The linkage between the Antarctic Oscillation (AAO) to the dust weather frequency (DWF) in North China is addressed. Here DWF denotes the number of days of dust weather events including dust haze, blowing dust and dust storm in one year. It is found that the interannual variation of AAO plays a significant role in the dust-related atmospheric circulation during boreal spring. AAO and DWF correlate well, with positive AAO tending to decrease DWF in North China. Two possible mechanisms for the AAO-DWF coupling are identified, one is related to a meridional teleconnection pattern; the other is related to a regional circulation pattern over the Pacific Ocean.
Feng Xue, Huijun Wang and Jinhai He, 2004: Interannual variability of Mascarene high and Australian high and their influences on East Asian summer monsoon. Journal of the Meteorological Society of Japan, 82(4),, 1173-1186
Based on the reanalysis data from NCEP/NCAR and other observational data, interannual variability of the Mascarene high (MH) and Australian high (AH) during boreal summer from 1970 to 1999 is examined. It is shown that interannual variability of MH is dominated by the Antarctic oscillation (AAO), and MH tends to be intensified with the development of the circumpolar lows in high southern latitudes. On the other hand, AH is correlated with AAO as well as El Nino and Southern Oscillation (ENSO), and tends to be intensified when El Nino occurs.<br /> Since AH, especially MH, is positively correlated with AAO, composite analysis on the difference between the positive and negative MH is performed to reveal the physical mechanism responsible for the East Asian summer monsoon anomalies associated with AAO. The result shows that, with the intensification of MH, the Somali jet, and Indian monsoon westerlies, tend to be strengthened. Accordingly, AH and the associated cross-equatorial flow, become stronger whereas the trade wind over the tropical western and middle Pacific become weaker. In association with the above changes, convective activities near the Philippine Sea are largely suppressed, as a consequence, exciting a negative convection anomaly, and a Rossby wave train from East Asia via the North Pacific to the western coast of North America (a negative Pacific-Japan pattern). Corresponding to the negative Pacific-Japan pattern, an anomalous rainfall pattern appears in East Asia.
Correlation analysis between AAO and sea level pressure, 500 hPa geopotential height further indicates that AAO is a strong signal influencing the climate anomaly in both hemispheres, including East Asia. Due to the seasonal persistence, AAO and the related MH and AH in boreal spring, may provide some useful information for the East Asian summer monsoon prediction. With the intensification of MH during boreal spring through summer, the Meiyu/Baiu rainfall from the Yangtze River valley to the Japan Islands tends to increase, while less rainfall is found outside of this region. In contrast with MH, the effect of AH on summer rainfall is confined to southern China.

With the boundary conditions appropriate for the Last Glacial Maximum (LGM), including ice sheets, sea surface temperatures, sea-ice distribution, atmospheric CO2 concentration, the Earth’s orbital parameters, topography, and coastline, the atmospheric general circulation model of the Institute of Atmospheric Physics (IAP-AGCM) computes colder and drier conditions than for present day. Global annual-average surface temperature decreased by 5.3°C, and terrestrial precipitation was down by 29%. It is shown that IAP-AGCM LGM simulation compares favorably to results from other AGCMs, and/but generally shows a weak terrestrial cooling when compared to paleoclimatic reconstructions in tropics. The 21 ka (ka: thousands of years ago) vegetation reconstruction is introduced into the model to study the regional climate response to the changes in vegetation and associated soil characteristics over China. The additional cooling due to these two changes reduces, to a certain degree, the model-data discrepancies. In addition, under the precondition of continental ice existing over part of the Tibetan Plateau at the LGM, the authors examine the regional climate response to the continental ice. It follows that the glacial-age environment over the Tibetan Plateau is a very important factor for 21 ka climate simulation in East Asia.

Wang Hui-Jun, Xue Feng, and Zhou Guang-Qing, 2002: The spring monsoon in South China and its relationship to large-scale circulation features. Advances in Atmospheric Sciences, 19(4), 651-664
In this paper, the authors define the spring monsoon in South China, and study the climatology and the interannual variation through analysis of the precipitation and the related atmospheric circulation, as revealed by the NCEP/NCAR reanalysis data. The results indicate that the spring monsoon season in South China occurs climatologically in April and May, which is supported by both seasonal and interannual variation of the atmospheric circulation and precipitation. The related atmospheric circulation is different from that during the East Asian summer or winter monsoon season. The interannual variation of the spring monsoon rainfall in South China relates primarily to the anomalous circulation over the North Pacific, which is linked with the westerly jet over North Asia and with the polar vortex. It is also connected with sea surface temperature anomalies in the Pacific. Changes in the Asian tropical atmospheric circulation have little influence on the spring monsoon in South China according to this research.
Wang Hui-Jun, 2002: The instability of the East Asian summer monsoon ENSO relations. Advances in Atmospheric Sciences , 19(1), 1-11
The instability in the relation between the East Asian summer monsoon and the ENSO cycle in the long term variation is found through this research. By instability, we mean that high inter relation exists in some periods but low inter relation may appear in some other periods. It is reveals that the interannual variation of the summer atmospheric circulation during the ‘high correlation’ periods (HCP) is significantly different from that during the ‘low correlation’ periods (LCP). Larger interannual variability is found during HCP for trade wind over the tropical eastern Pacific of the Southern Hemisphere, the low—level air temperature over the tropical Pacific, the subtropical high pressure systems in the two hemispheres, and so on. The correlation between summer rainfall over China and ENSO is as well different between HCP and LCP.
Wang Hui-Jun, 2001: The Weakening of the Asian Monsoon Circulation after the End of 1970s. Adv. Atmos. Sci, 18(3), 376-386
The transition of the global atmospheric circulation in the end of 1970’s can clearly be detected in the atmospheric temperature, wind velocity, and so on. Wavelet analysis reveals that the temporal scale of this change is large than 20 years. Studies in this work indicate that the trend of the transition over the mid-latitude Asia is opposite to that of global average for some variables at the middle troposphere. Another finding of this research is that the African-Asian monsoon circulation is weaker and the trade wind over the tropical eastern Pacific is weaker as well after this transition. Such a signal may be found in the summer precipitation over China as well.
WANG Huijun, CHEN Xingyue, XUE Feng and ZENG Qingcun, 2001: The Intraseasonal Oscillation And Its Interannual Variability - A Simulation Study. Acta Meteorologica Sinica, 15(1), 49-58
The atmospheric intraseasonal oscillation(ISO) and its interannual variability are simulated by the atmospheric circulation mode, which was developed at the Institute of Atmospheric Physics. Two numerical experiments were performed, corresponding to the AMIP-I and AMIP-II simulations, respectively. The model reasonable reproduces the majao aspects of the ontraseasonal oscillation, including the propagating property and the seasonal differences in the tropics, the wavenumber structure of ISO in the globe,and the globle coincidence in the interannual variation of ISO. Comparison of the results between the two experiments suggests that improvement of the boundary forcing or condifering the air-sea interaction may help to improve the simulation on the ISO and its interannual variability.
Wang H.J, 2000: The interannual variability of the East Asian monsoon and its relationship with SST in a coupled atmosphere-ocean-land climate model. Adv. Atmos. Sci, 17(1), 31-47
Based on a 200 year simulation and reanalysis data (1980 1996), the general characteristics of East Asian monsoon (EAM) were analyzed in the first part of the paper. It is clear from this re-search that the South Asian monsoon (SAM) defined by Webster and Yang (1992) is geographically and dynamically different from the East Asian monsoon (EAM). The region of the monsoon defined by Webster and Yang (1992) is located in the tropical region of Asia (40 110°E, 10 20°N), including the Indian monsoon and the Southeast Asian monsoon, while the EAM de-fined in this paper is located in the subtropical region of East Asia (110 125°E, 20 40°N). The components and the seasonal variations of the SAM and EAM are different and they characterize the tropical and subtropical Asian monsoon systems respectively. A suitable index (EAMI) for East Asian monsoon was then defined to describe the strength of EAM in this paper. In the second part of the paper, the interannual variability of EAM and its relationship with sea surface temperature (SST) in the 200 year simulation were studied by using the composite method, wavelet transformation, and the moving correlation coefficient method. The summer EAMI is negatively correlated with ENSO (El Nino and Southern Oscillation) cycle represented by the NINO3 sea surface temperature anomaly (SSTA) in the preceding April and January, while the winter EAM is closely correlated with the succeeding spring SST over the Pacific in the coupled model. The general differences of EAM between El Nino and La Nina cases were studied in the model through composite analysis. It was also revealed that the dominating time scales of EAM variability may change in the long-term variation and the strength may also change. The anoma-lous winter EAM may have some correlation with the succeeding summer EAM, but this relation-ship may disappear sometimes in the long-term climate variation. Such time-dependence was found in the relationship between EAM and SST in the long-term climate simulation as well.

An effective method was proposed for correcting the seasonal—interannual prediction of the summer climate anomaly. The predictive skill can be substantially improved by applying the method to the seasonal—interannual prediction carried out by a coupled ocean—atmosphere model. Thus the method has the potential to improve the operational summer climate predictions.

Wang Hui-Jun, 2000: The seasonal climate and low frequency oscillation in the simulated mid-Holocene Megathermal climate. Adv. Atmos. Sci, 17(3), 445-457
The mid—Holocene climate about 6000 years ago was simulated by using the atmospheric general circulation model. The orbital parameters for 6 ka BP (before present) were prescribed and other forcing factors were set in the modern conditions. Results show that the large—scale climate change in the African—Asian monsoon areas during the summer—time is strongly compared to the present climate, while the changes in other seasons and regions are generally weak. The results also revealed the change of the low frequency oscillation in the atmosphere.

Sets of numerical hindcast experiments were carried out to study the excessive rain that happened over China in 1998 by using an atmospheric general circulation model. The monthly sea surface temperatures for 1998 were prescribed as the model boundary conditions. The initial atmospheric conditions for each of the 30 member simulations were obtained from the daily reanalysis data for 00 UTC from April 1 to April 30, 1998. The initial conditions for snow mass, soil temperature, and soil wetness were prescribed as those of the model climatology.<br /> The ensemble averages of the 30 member hindcast experiments captured the positive rainfall anomaly occurred over China in the summer of 1998, with 5 degree of northward shift. The observed patterns of summer geopotential anomalies were qualitatively reproduced as well. It was revealed that initial atmospheric anomalies in April have apparent impacts on the simulated flow patterns over Eurasia and the North Pacific, and rainfall anomalies over China during the summer of 1998. However, the overall results suggest that tropical sea surface temperature anomaly played a key role in heavy rainfall over China in 1998.

El Nin˜o and the related phenomenon Southern Oscillation (ENSO) is the strongest signal in the interannual variation of ocean-atmosphere system. It is mainly a tropical event but its impact is global. ENSO has been drawing great scientific attention in many international research programs. There has been an observational system for the tropical ocean, and scientists have known the climatologies of the upper ocean, developed some theories about the ENSO cycle, and established coupled ocean-atmosphere models to give encouraging predictions of ENSO for a 1-year lead. However, questions remain about the physical mechanisms for the ENSO cycle and its irregularity, ENSO-monsoon interactions, long-term variation of ENSO, and increasing the predictive skill of ENSO and its related climate variations.
Wang Hui-Jun, 1999: Role of vegetation and soil in the Holocene megathermal climate over China. JOURNAL OF GEOPHYSICAL RESEARCH, 104(8), 9361-9367
There was significant difference between vegetation cover in mid-Holocene and that at present over China based on various evidences as concludes by Shi et al . These changes were introduced to the climate model to study the role of the changing vegetation and associated soil to the simulated climate of mid-Holocene at 6000 years before present (BP) with bigger seasonal cycle of insolation than present (caused by the change of orbital parameters). Results show that the changes in vegetation and soil could further strengthen the monsoon rainfall over China. We found that replacing the today’s seasonal cycle of insolation by that of mid-Holocene increases the summer (June-August) precipitation by 20% in eastern China (100-120E,18-42N); while considering both the effect of changing orbital forcing and the vegetation and soil, the total summer precipitation increase in 29% in the same region. Compared with the reconstructed precipitation over China, the results of that including changing vegetation and soil is quantitatively better.

Wang Huijun, Xue Feng and Bi Xunqiang, 1997: The interannual variability and predictability of a global climate model. Advances in Atmospheric Sciences, 14(4), 554-562
The interannual variabilities of the climatological simulation (V1) and the AMIP (Atmospheric Model Intercomparison Project) simulation (V2) by the IAP 9-Level Atmospheric General Circulation Model are studied and discussed in this paper. Based on the analysis of ratio of variability (R) of above two simulations the predictability of the model on the interannual climate variation are studied as well. Results show that V2 is bigger than V1 generally and V2 is more comparable to the real variability of the atmosphere, the major difference of V1 and V2 is in the tropics, for temperature and geopotential height the predictability is higher in the tropics while in the extra-tropics there is almost no predictability and the predictability is bigger in higher level than in lower level. The predictability for precipitation is generally low in the globe, and generally the predictability is high in the tropical eastern Pacific for the lower level. This study suggests that the possible way of increasing the model predictability is the improvement of land surface process modelling and the inclusion of the interannual variations of the land surface conditions (snow cover, albedo, soil moisture, etc.) as the forcing factor for climate modelling and prediction.
