摘　　要：利用广西钦州风电场一座距地80 m高度测风塔上的测风仪,收集到强台风"彩虹"影响期间的风况数据,对风况参数特征进行了分析研究,结果表明:(1)台风"彩虹"经过测风塔前后,风向由北风转为南风,风速急剧减小,湍流强度出现突增现象;(2)测风塔湍流强度大于B级,风速越小湍流强度越大;(3)高度越高、风速越大,阵风系数越小;(4)风速垂直切变符合幂指数规律,风速越大,其垂直切变越小。An analysis is made on the wind regime characteristics based on the data of Typhoon “ Mujigae” observed by the anemometer on an 80m high wind tower in Guangxi Qinzhou wind farm. The results show that： ① the wind direction of “ Mujigae” turns from north to south after passing through the wind tower, the wind velocity decreases rapidly and the turbulence intensity increases suddenly;② the turbulence intensity level is greater than B ; and the lower the wind velocity, the higher the turbulence intensity is;③ the higher the altitude and the greater the wind speed, the smaller the gust factor is;④ the characteristic of the vertical wind shear obeyed to power exponent law, and the greater the wind speed, the smaller the vertical wind shear is.
