  • By using the statistics method and numerical simulations, influences of SSTA in Indian Ocean, South China Sea and southeastern coastal region of China on Yangtze-Huaihe River valley precipitation is undertaken. The results of statistic analysis show that the precipitation is plentiful (deficient) when the SSTA is positive (negative) anomaly. On the basis of analyzing OLR data, OLR of Yangtze-Huaihe River valley is positive (negative) anomaly when the OLR in Indian Ocean is positive (negative) anomaly, but the OLR of South China Sea and southeastern coastal region of China is negative (positive) anomaly. The results of numerical simulation show that the blocking high of middle-high latitude is stronger and the precipitation of Yangtze-Huaihe River valley is excessive when the SSTA of Indian Ocean is positive. In coastal region of East Asia, the general circulation is same with that of less rainfall of Yangtze-Huaihe River valley, in good agreement with statistical facts.
