摘要
对１９５４年以来南海登陆的热带气旋与浙北地区出梅期进行了比较系统的分析，发现热带气旋登陆造成出梅的概率占登陆热带气旋总数的５４％，在南海的北部和西北部登陆的热带气旋，使浙北地区出梅的概率远高于南海其他区域登陆热带气旋的出梅概率。通过对出海和出梅热带气旋的环流型及前期环境流场特征的对比分析，揭示出两者在西太平洋副高和西风帝系统存在着明显的差异。
An analysis of the tropical cyclones landing in South China Sea andends of the plum-rains period in the north of Zhejiang Province Since1954 is given,It has been found that the probability of the end of theplum-rains period caused by tropical cyclone landing is 54 per cent ofthe total of landing tropical cyclones. The probability of end of theplum-rains period in the north of Zhejiang province caused by the tropical cyclones landing in the north and north-west of Sorth China Sea ismuch bigger than in the other portion Comparing the flow pcettern andearlier characteristics of corresponding envi ronmental flow fields for thetropical cyclones either causing or not-causing the ends of the plumrains,it has been reyealed that there are obvious differences betweenboth of them in the west Pacific highs and in the westerly systems.
