Possible Impacts of the Tropical Indian Ocean SST Anomaly Modes on the South China Sea Summer Monsoon Onset
热带印度洋海温异常不同模态对南海夏季风爆发的可能影响

There are two major sea surface temperature anomaly (SSTA) patterns over the tropical Indian Ocean (TIO):basin-wide SSTA variation which peaks in the boreal spring,and the dipole mode that is phase-locked in the boreal autumn. This paper explores possible impacts of these two SSTA patterns on the South China Sea (SCS) summer monsoon onset. Using composite analyses,it is revealed that basin-wide warming (cooling) in the TIO apparently induces an anomalous reversed (intensified) Walker circulation over the tr...
