| 摘 要： | 按国家气象局“八五”攻关力专家组提出的有关近海热带气候强度突变的标准，对１９７０－１９９１年在我国的近海发生强度突为的热带气旋进行了分类统计，发现如下气候特征：平均每年有８－９个热带气旋移到我国近海时发生强度突变，其中突然减弱的居多，占总个数的７９．６％，突然增强的只占总个数的２０．４％，突然增强只发和天５－１０月，而突然减弱到５－１２月均可发生；突然增强主要出现在浙闽沿海、南海中部，珠江口外西侧

| Abstract: | Twenty years of wind stress and SSTA data for the tropical Pacific are studied by the EOF method so that the characteristic modes of spacial distribution and features of temporal variation are revealed.It was shown that the first eigenvectors of both the field of wind stress and sea temperature have the same features of variation,representing the interaction and coupling relationship at this temporal and spacial scale between the ocean and atmosphere and being consistent with the El Nino cycle. |
