Abstract
The relationship between the interannual variations of the East Asian summer monsoon and that of the tropical
SST shows considerable variations. In this study, rainfall in the southeastern coastal area of China (SEC) during
1951–96 is used to composite the tropical SST, 850-hPa wind, and 500-hPa height. The results relative to the
May–June rainfall, which represents most of the SEC summer monsoon rainfall, are compared to the Yangtze
River Valley (YRV) rainfall composites. It is shown that strong interdecadal changes in the Pacific may account
for the observed variations in the meridional structure of the monsoon–SST relationship. The western Pacific
500-hPa subtropical ridge, which is influenced by the equatorial eastern Pacific SST, is crucial to these variations.
