| 摘 要： | 资料统计分析显示，ＥｌＮｉｎｏ年，影响福建的热带气旋较常年显著偏少，ＬａＮｉｎａ年，影响福建热带的气旋较常年偏多，ｔ检验表明，两者之间差异显著。其机制是，ＥｌＮｉｎｏ活动期间，西太平洋副热带高压强度大，位置偏南、偏西、ＩＴＣＺ位置偏南，热带气旋生成区对流活动弱，不利于热带气旋的生成和北上影响福建，ＬａＮｉｎｅ年，副热带高中度北，位置偏北，偏东，ＩＴＣＺ位置偏北，热带气旋生成区对流活动旺盛，有利于热

| Abstract: | Analysis show that the tropical cyclones which influence Fujian are fewer in El Nino years and more in La Nina years then normal. The mechanism is that in El Nino years, subtropical high over West Pacific is stronger and more southerly and westerly, ITCZ is more southerly located, and convection over West Pacitic is weaker. All above unfavorable to the forming and moving northerly of the tropical cyclones. In the La Nina years, the situation is quite the opposite. |
