摘要： 选取1949~1999年影响上海沿海的强风暴潮过程及其所造成的相应灾害资料，研究强风暴潮过程和特强风暴潮过程的时空分布，并进行灾情分析.得出影响上海的强风暴潮过程特征和规律如下：1)严重影响上海地区的强风暴源地主要分布在7~20 °N，122~165 °E的范围内，占总数83.3%；2)严重影响上海地区的强风暴潮过程主要发生在8月和9月，它们均占总数的38.3%;3)强风暴潮及特强风暴潮过程遇天文大潮汛的频率很高，这将大大增加超越警戒水位和致灾的可能性；4)影响上海地区的强风暴潮过程，主要以沪、浙登陆型台风和海上中、西转向型台风为主，它们占强风暴潮过程总数的90%以上;特强风暴潮过程一般均属台风在上海、浙北登陆型和西转向型；5)侵袭上海的特大潮灾平均约10 a出现1次，而其中2次是在最近3 a出现的，说明该地区风暴潮灾害有加剧的趋势.

Abstract: Based on the strong storm surge data from 1949 to 1999 that affected Shanghai regions and the storm-induced calamity data, the temporal and space distribution of strong and unusual strong storm surge process, and their disaster analysis are investigated. Several conclusions have been drawn as follows: 1) The origins of strong storm affecting Shanghai were mainly distributed in the range of 7~20 °N, 122~165 °E, 2) The strong storm surge processes attacking Shanghai happened mainly in August and September, 3) When a strong storm surge encountered astronomical tide, the upsurge often exceeded the alert water level and induced calamity, 4）The strong storm surges affecting Shanghai are mainly landing in Shanghai, Zhejiang and west turning in the sea, 5) The unusual strong storm surge attacking Shanghai happened once about 10 years.
