| 摘 要： | 本文用统计学方法对厄尔尼诺事件(包括反厄尔尼诺事件,下同)与登陆我国热带气旋之间的关系作了初步分析。结果表明,厄尔尼诺年当年登陆我国的热带气旋较常年偏少,登陆纬度偏南,其中的台风登陆频数亦较常年偏少;而反厄尔尼诺年当年则相反。分析还表明,上述影响的可能机理是,厄尔尼诺事件发生时异常海温影响沃克环流、哈得来环流及副高脊线位置的结果。

A preliminary analysis of the relationship between the tropical cyclones landing on china and El Nino events |
| |
| Abstract: | In this paper, the relationship between the tropical cyclones landing on China and the El Nino events is statistically analysed. The results show that of the tropical cyclones and typhoones landing on China are less in El Nino years and more in anti-El Nino years. So are the landing latitudes. The degree of these relationships is diverse in different moths and latitude regitons. Its possible reason is caused by abnomal Walker and Hadley Circulation and the position of Subtropical high ridge during the. El Nino events. |
