摘　　要：针对广州超大城市综合观测建设中,为了获取典型天气过程特征风数据,需使用最优观测设备连续观测城市上空边界层内风分布状况的问题,选取3部不同类型的测风雷达与清远探空站数据进行对比分析。通过计算测风雷达数据的可用率、风向风速准确率及误差情况,对3部测风雷达的探测效能做出评估,得出在边界层内不同垂直高度上探测效能最优的设备,为广州超大城市综合观测建设提供依据。Aiming at the problem that the optimal observation equipment must be used to continuously observe the wind distribution in the boundary layer over the city in order to obtain the characteristic wind data of typical weather process in the comprehensive observation construction of Guangzhou, this paper selected three different types of wind radars and Qingyuan radiosonde data for comparative analysis. By calculating the availability, accuracy and error of wind radar data, the detection efficiency of three wind radars was evaluated,and the equipment with the best detection efficiency at different vertical heights in the boundary layer was obtained, which provides a basis for the comprehensive observation construction of Guangzhou.
