%X Orthogonal wavelet analysis of summer rainfall in East China showed its opposite spatial pattern before and after the 1970s,mainly the opposite situation of precipitation in North China and in the middle and lower reaches of the Yangtze River.The difference of meridional position of the summer East Asian upper-tropospheric Jet Stream(EAJS) and West Pacific Subtropical High(WPSH) before and after the 1970s was one of the most important reasons for the transition of summer rainfall pattern.Besides,on interdecadal time scales,North Pacific and Tropical Indian Ocean Sea Surface Temperature Anomaly(SSTA) variated coherently,and were closely related to the transition of summer rainfall pattern in East China.What's more,North Pacific-Equatorial Indian Ocean Sea Surface Temperatures(SST)showed a certain relationship with the north-south movement of EAJS and WPSH on both interannual and interdecadal time scales.Thus,North Pacific-Equatorial Indian Ocean SST was indeed an important factor for the prediction of summer rainfall pattern in East China.
