| 摘 要： | 本文对厄尼诺年(赤道东太平洋SST有持续正距平)和反厄尼诺年(赤道东太平洋SST有持续负距平)南海的台风(包括进入南海的西太平洋台风和在南海生成的台风)活动进行了统计分析。结果表明,厄尼诺同南海的台风活动有明显关系:厄尼诺年平均台风数偏少,反厄尼诺年平均台风数偏多,其异常主要发生在8—11月份;在两广沿海登陆的平均台风数也是厄尼诺年偏少,反厄尼诺年偏多,其异常以10和11月最显著;在北部湾海域活动的台风多在8—9月份,也是厄尼诺年偏少,反厄尼诺年偏多。 文本也对厄尼诺如何影响南海的台风活动提出了初步看法。

| 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. |
