摘　　要：研究了1951—2001年南海夏季风及副热带夏季风不同强度配置下梅雨异常的同期对应关系。结果表明,这9种配置可以分成三类：易多雨类、易少雨类及不确定类。对三类配置下我国东部6-7月雨区和高度距平场的合成分析得到各类季风配置下,我国降水分布特点及相应的高度距平场特征。这种分类和分析有助于对梅雨与季风关系,特别是对不确定类配置与梅雨关系的认识和预报。由于本地业务工作需要,同时对上海及高相关区进行了分析,得到的结果与长江5站大致相同,但略有差异。An investigation is performed to probe the relationship between Meiyu and the intensity of East Asian summer monsoon based on Meiyu rainfall and Monsoon indices series for 1951--2001. Some clear facts are revealed： There are 9 matching patterns between South China Sea summer monsoon and Subtropical summer monsoon, which can be classified as 3 categories by Meiyu rainfall anomaly： Rainyprone, rainless-prone, and uncertainty. Composited analyses of rainy areas and geopotential height for each pattern reach some results which is significant for the recognization and long-term forecast of Meiyu.
