摘　　要：近年来,中国夏季降水异常事件频发,并已严重影响社会经济的发展,所以研究其异常成因是我国学者刻不容缓的任务。中国夏季降水带有明显的区域性特征。通过分析海温场与中国各区域夏季降水的关系,得到以下结论:前期和同期海温场的变化对当年夏季降水的影响基本一致。当赤道印度洋东部海域、暖池海温偏高,而太平洋中东地区的海温偏低时,两河中上游流域及其以南区域降水偏多,即中国东南区域以及西南部分区域降水偏多。Since the occurrence of abnormal summer precipitation events in China has seriously affected the development of social economy in recent years,it is an urgent task for Chinese scholars to study the corresponding causes.The summer precipitation in China has obvious regional characteristics.After analyzing the relationship between the SST and summer precipitation in various regions of China,it draws the following conclusions:The changes of the SST in the previous and the same period have basically the same influence on the summer precipitation in the same year.Meanwhile,the SST in the eastern equatorial Indian Ocean and the warm pool is relatively high.However,the SST in the Middle East of the Pacific is relatively low,and the precipitation in their middle and upper reaches along with the southern regions is relatively high,namely,the precipitation in the southeast and partial southwest of China is relatively high.
