THE MULTI-TIME SCALE VARIATIONS OF SUMMER MONSOON OVER SOUTH CHINA SEA AND ITS INTERACTION WITH SST ANOMALY

Using reanalyzed data of NCEP and observational data of OLR and SST, the features of multi-time scale variations of summer monsoon are studied, and the differences of the atmospheric circulation between strong and weak summer monsoon years are analyzed. It is shown that there exists obvious interplay between the summer monsoon variation over the South China Sea and SST, and meanwhile the variation of SST has a certain effect on summer monsoon.
