Abstract: In present paper,some statistic analysis on the typhoon actions over South China Sea (including typhoons which come from western Pacific area) in El Niño years (SST in the equatorial eastern Pacific area is continued on the high side abnormally) and in inverse El Niño years (SST in the equatorial eastern Pacific area is negative anomaly continuously) are completed. The results show that the actions of typhoon over South China Sea are in close relation with El Niño: The average number of typhoon in El Niño years is less than normal and is more than normal in inverse El Niño years,. The anomalies mainly occur during August-November; The average landing typhoon number on the continent of both Guangdong and Guangxi is also less in E1 Nino years and more in inverse El Niño years. It is clear that the anomalies of the month- average landing typhoon number occnr in October and November; The actions of typhoon over Beibu Gulf area are mainly in August and September and less than normal in E1 Nino years while more in inverse El Niño years.The preliminary views about the anomaly mechanism of the typhoon actions over South China Sea forced by SST in equatorial eastern Pacific are indicated in this paper.
