%X Based on the ECMWF reanalysis data from 1979- 1993 and TBB data of CMS, an analysis on the onset of the summer monsoon over the South China Sea (SCS) is made. It is found the mean onsel dale is on the 16th of May. There is marked inlerannal variation of the onset day, the earliest day is in the beginning of May, and the latest onsel day is in beginning of June. In some years in the last ten days of April ihere appears marked south west How over the SCS, but the south west How only persists for more than a shorl period, and the easterly flow reappears. In the beginning of June the true onset appears. From the end of April to the middle of May before the onsel, in the SCS there appears strong south west flow to the north of 15N. These strong westerly flow are due to the soulhward advance of cold front or due to the strenglhening of the subtropical high in the SCS, and the westerly How can not be treated as the onset of the SCS summer monsoon. After the onset, there are active and break period of the south west summer monsoon flow, the average break period is about 15 days in each year.
