| 摘 要： | 用相关和SVD方法分析讨论了不同季节全球海温异常与长江流域夏季降水的联系，并用合成分析探讨了这种相互联系的可能机制。结果表明，当前期冬季赤道东太平洋海温、同期夏季西太平洋暖池和赤道印度洋海温偏高时，热带季风偏弱，副热带季风偏强，冷暖气流在长江流域交汇，梅雨锋加强，有利于长江流域夏季降水偏多。

| Abstract: | Based on the correlation and SVD methods, the relationship between the summer rainfall in Changjiang River basin and the SSTA of different seasons are studied. The results show that if the SSTA of EEP in winter and that of TWP and EI in summer is warmer than normal, the tropic monsoon will become weaker, and the subtropic monsoon will become stronger. The cold and warm airflow will converge in the Changjiang River basin and the Mei-yu front will be strengthend, then the rainfall of summer in Changjiang River will be much more than average. |
