指出ElNino年登陆和影响福建的热带气旋较常年显著偏少，而LaNina年则较常年偏多。其机制是EiNino活动期间，西太平洋副高强度大，位置偏南、偏西，强对流带ITCZ位置偏南，热带气旋生成区对流活动弱；LaNina年西太平洋副局强度小，位置偏北、偏东，ITCZ位置偏北，热带气旋生成区对流活动旺盛，有利于热带气旋的生成及北上登陆或影响福建。 It is pointed out that the annual number of El Nino landfalls and the tropical cyclones affecting Fujian Province are significantly less than those of normal years, while LaNina years are more frequent than those of normal years. The mechanism is that during the EiNino event, the convective activities in the tropical cyclone zone were weaker in the western Pacific subtropical high, southwest, west and strong convective zone ITCZ ​​and weak in the tropical cyclone zone. In the LaNina, In the east, the ITCZ ​​locates northward and the convective activity in the tropical cyclone generating area is strong, which is favorable to the formation of tropical cyclones and landing northward or affecting Fujian.
