Abstract: Based on the strong wind data of the coastal stations in Fujian province from 1987 to 2016,the NCEP reanalysis data and FY2C satellite TBB data,the typhoon gale and extreme gale on the west coast of the Taiwan Strait in China were defined and analyzed by using statistical and meteorological diagnostic methods.The results show that the typhoon gale on the west coast of the Taiwan Strait in China is mainly 7-9 grade and the extreme gale is 10-14 grade. The central region of the west coast is a windy disaster area.The typhoon samples in the studied period are classified into four types according to their paths.As a result,it is found that the most typhoons that produce strong wind land at the central region of Fujian to the central region of Zhejiang and the south of Fujian to the east of Guangdong,and the strong wind regions are generally located on the right of the paths.Meanwhile,two typical cases of typhoons named 0608 Sangmei and 1614 Meranti which produce extreme wind are compared and investigated.The results show that the terrain which are high in the north and low in the south and the strong pressure gradient is in favor of early producing the gale.In addition,the stimulated growth of the mesoscale convection in the lower layer with cold advection invading in the middle layer over typhoons is the cause enhancing the ground gale.

Key words: West coast of the Taiwan Strait, Strong typhoon wind, Extreme wind
