Using the multilayer wind data of the Typhoon Kalmaegi from the 90 m meteorological anemometer tower in Hainan Province, this paper analyzes the spatial and temporal characteristics, turbulence intensity, vertical wind shear and gust coefficient of the surface wind during the landing of Typhoon Kalmaegi. The results show that the nearsurface wind at different heights presents the “M” pattern during the typhoon’s landfall. The maximum wind speed appears in the rear wind circle. The wind direction rotates around by 180° before and after the typhoon sweeps the area. The nearsurface wind increases along speed with the increase of height. The vertical shear of wind speed at different heights accords with logarithmic and exponential rule. Roughness, wind profile exponent, turbulence intensity and gust coefficient have negative correlations with the wind speed. They decrease with the wind speed’s increasing. The roughness characteristic is “increasingdecreasingincreasing” with the wind speed from typhoon periphery to eye. The wind speed vertical shear is strong in the typhoon eye and weak in the wind circle. The turbulence intensity is weak in the strong wind area and strong in the weak wind area. The turbulence intensity decreases with height in the typhoon wind circle but the situation is opposite in the typhoon eye. In general, the gust coefficient increases with the hight and conforms to exponential rule in different layers. In addition, the gust coefficient decreases with the wind speed until the wind speed reaches a high level.
