We investigated the interannual variability of the South Asian summer monsoon (SASM) circulation, which has experienced a significant interdecadal change since 2000. This change is primarily influenced by sea surface temperatures (SSTs) in the tropical Pacific and North Atlantic Oceans. During the pre-2000 period examined in this study (1979‒1999), the SASM is negatively correlated with eastern Pacific SSTs (the canonical El Niño-Southern Oscillation (ENSO) mode) and positively correlated with the negative phase of the North Atlantic SST tripole (NAT). During the post-2000 period (2000‒2014), the SASM is negatively correlated with central Pacific SSTs and positively correlated with the positive phase of the NAT pattern. The associated Pacific SSTs change from eastern to central region, leading to the rising (subsiding) branch of the Walker circulation moving westward to the Maritime Continent in the latter period, which can impact the interannual variability of the SASM through modulating the wind field in the troposphere. In addition to Pacific SSTs, the NAT SSTs can propagate energy from North Atlantic to South Asian High (SAH) region through the wave activity flux, then further impact the SASM via SAH.<br /> Because the SASM is intimately related with precipitation over the Asian region, we briefly discuss the features of the precipitation patterns associated with the SASM during the two periods. The westward shifting Walker circulation leads to the shrinking and weakened anomalous westerlies of SASM in the lower level, inducing the Maritime Continent rainfall location moving westward and more moisture from Pacific Ocean can arrive at the Southern China in the latter period.
Gao Ya, 2017: Shift of the principal mode of Pan-Asian monsoon summer precipitation in terms of spatial pattern. 10, 3, 221-227
In paper, it is documented that the principal mode of the Pan-Asian monsoon summer precipitation has experienced a prominent interdecadal shift around 1992/1993 in terms of spatial pattern and major driving factors. During 1979‒1992 (Period 1‒P1), Pan-Asian monsoon summer precipitation anomalies mainly display a meridional dipole pattern from north to south, whereas in the period 1993‒2016 (Period 2‒P2), it shows a meridional tripole pattern instead. The summer precipitation in P1 is primarily associated with a combination of the developing phase (central-eastern Pacific type) and decaying phase (eastern Pacific type) of El Niño-Southern Oscillation (ENSO) mode; while in P2, it is mainly associated with the eastern Pacific type of ENSO decaying phase.<br />
