Impacts of the previous winter Kuroshio SSTA on summer rainfall in China are simulated and analyzed in terms of the NCAR CCM3.Results indicate that there is a close relationship between previous winter Kuroshio SSTA and summer precipitation in China.When the previous winter Kuroshio SSTA is anomalously high,in the following summer the Western Pacific subtropical high becomes stronger and west-extending,and the Asian summer monsoon is weaker and the Meiyu front lies more southward.As a result,the summer precipitation is more than normal in the Changjiang-Huaihe River reach and in the mid-lower reaches of the Yangtze River,and less than normal in North and Northeast China;and vice versa.
