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.
