Typhoon which we concerned includes tropical storm,severe tropical storm and typhoon.The best track data record typhoon information,such as center location,central lowest pressure and maximum wind speed every 6 hours,which are retrieved from China Meteorological Administration (CMA).According to the dataset of radii of specific wind speeds (15.4m/s and 24.5m/s),the radius of maximum wind speed and coefficient of wind profile were regressed.After calculating wind field of every typhoon record via Miller Wind-Field Model,the results showed that wind intensity decreased from southeast coastline to northwest inland in China; and the strongest zones lie in Taiwan island,Hainan island and the west coastline of Guangdong province.
