Abstract:
The periodic analysis was conducted for the frequency of the tropical cyclones landing on China using the mathematic statistical method. The linear correlation was found between the maximum wind speed near the Center V1, V2, V3 (24hr, 12hr and 6hr before landing) , respectively, and the difference of the mean maximum wind speed (24hr after landing) and V1, V2, Vs (ΔV1, ΔV2, ΔV3) . The regression equations were obtained respectively for the tropical cyclones landing on Taiwan, Hainan, Guangzhou and Fujian provinces of China.
