摘　　要：本文主要通过对海温异常的埃尔-尼诺年反埃尔-尼诺年,西北太平洋热带气旋活动特征的分析,发现在反埃尔-尼诺年,热带气旋发生频次高,生成位置比常年分布范围大,位置偏北,影响或登陆浙江的热带气旋比常年多。在埃尔-尼诺年,热带气旋发生的频次低,发生区位置比常年偏东、偏南,影响或登陆浙江的热带气旋比常年少。Analysis of activity characteristics for tropical cyclones over the Northwest Pacific during El Nino and anti-El Niso years of SST anomalies shows that compared with the normal years, in anti-El Nino years tropical cyclones have higher frequency of occurrence , larger range and farther north position of origin location, and more opportunity to affect on land Zhejiang;while in El Nino years,they have lower frequency of occurrence, farther east or west position of origin location, and less opportunity to affect or land Zhejiang.
