The spring persistent rains(SPR)over southeastern China(SEC)are a unique synoptic and climatic phenomenon in East Asia.A former study has found that the southwesterly flow which lies on the southeastern flank of the Tibetan Plateau(TP)is one of the deflected westerly flows of the TP,and it is suggested to be the direct climatic cause of SPR.This study found that the southwesterly flow is also highly correlated with the sensible heating of the southeastern TP in interannual variability,in addition to having ...

1.IntroductionThe Tibetan Plateau(TP)is the highest and thesteepest topography in the world.It is recognizedthat its mechanical forcing significantly influences theatmospheric circulation of the Northern Hemisphere(Queney,1948;Hahn and Manabe,1975;Hoskins
