Abstract :
Relationship were investigated between winter Pacific sea surface temperature (SST) and summer extreme precipitation events (EPE) of east China. Result suggests that the previous winter tropical western Pacific is a key region influences on the summer extreme precipitation events (EPE) over Northeast and the Jiangnan of China. If sea surface temperature anomalous (SSTA) happens there in the winter, then there is an anomalous meridional vertical circulation averaged over 105-135degE from winter to summer, producing anomaly in vertical motion in summer over the two parts of east China, as a result, anomalous summer extreme precipitation events (EPE) happens there.
