摘      要：Interannual variation in summer rainfall over South China （SC） was investigated on the monthly *** was found that monthly rainfall from May to August exhibits different features of variation,and the amounts are basically independent of each *** is a significant negative correlation,however,between May and July SC rainfall,which is partially related to the developing phases of ENSO *** was also found that stronger （weaker） lower-tropospheric winds over SC and the upstream parts are responsible for more （less） SC rainfall in every month from May to *** this monthly consistent enhancement of horizontal winds,the wind anomalies exhibit distinct differences between May-June and July-August,due to the remarkable change in climatological winds between these two *** SC rainfall is associated with a lower-tropospheric anticyclonic anomaly over the SCS and the Philippine Sea in May and June,but with a cyclonic anomaly centered over SC in July and August.
