| Abstract: | The characteristics of disaster which was caused by tropical cyclone (TC)from 1949 to 2007 influencing Zhejiang province were analyzed, based on 84 TC cases and their disaster condition. Next, The objective quantitative grades of TC disaster were separated with disaster index of TC (G)and disaster losing ratio (S). At the same time, the relation between disaster condition and TC path, the factor of disaster (precipitation and wind power), and spring tide comes from the statistic analysis, whose aim is to provide the valuable evaluating method and criterion on TC disaster condition before its occurrence. |
