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。
In this paper, typhoon (including the western Pacific typhoon entering the South China Sea and the South China Sea formed in the equatorial East Pacific SST with continuous positive anomaly) and the EIN (continuous equatorial SST with equatorial East Pacific) Typhoon) activities conducted a statistical analysis. The results show that there is a clear relationship between the EINO and the typhoon activity in the South China Sea: the annual average typhoon Ernie is too small and the average number of typhoon Ebinuria is large, the anomaly mainly occurs from August to November; The average number of typhoons is also less than that of the Ernio year, and the number of anti-Erno years is too much. The anomaly is most notable in October and November. The typhoon activities in the Beibu Gulf are mostly in the August-September period, Less, more than anti-E Nino years. The text also provides a preliminary view of how Ernie Typhoon affected the typhoon activities in the South China Sea.
