摘　　要：利用同址气球探空数据对2023年1—6月思茅站风廓线雷达资料进行了质量评估,并结合多普勒天气雷达、自动气象站资料,分析了不同强对流天气过境时两者的测风差异特征,进一步检验了思茅站风廓线雷达资料的准确性和可用性.结果表明:①思茅站风廓线雷达具有较强的探测能力,近地面至对流层中层数据获取率在80%以上,有效探测高度约5 km;②风廓线雷达和同址气球探空的风垂直廓线整体呈现较为一致的趋势,思茅站风廓线雷达资料有良好的可靠性;③风廓线雷达V风测风质量优于U风.U风和V风同时满足相关系数大于0.6.均方根误差小于6.5 m/s的层次与雷达的有效探测高度相对应;④在不同强对流天气下,思茅站风廓线雷达数据仍具有准确性和可用性,一些中小尺度系统在风羽图上都有很好的展示.By using balloon sounding data at the same site,the quality of wind profile radar data was evaluated at Simao Station from January to June 2023.To further test the accuracy and availability of wind profile radar data at Simao Station,the differences of wind observational data under different strong weather conditions were also analyzed in combination with the data of Doppler weather radar and automatic weather station.The results showed that:①the wind profile radar at Simao Station had strong detection ability,with the data acquisition rates over 80%from surface to middle of the troposphere,and an effective detection altitude of about 5 km.②The vertical wind profiles of the wind profile radar and the balloon sounding data displayed consistent trends,and the wind profile radar data at Simao Station had good reliability.③The observational quality of wind profile radar for V wind was superior to that for U wind.The levels,where the correlation coefficients were greater than 0.6 and the root mean square errors were less than 6.5 m/s for both U and V winds,corresponded to the effective detection height of the radar.④Under different strong weather conditions,the wind profile radar data at Simao Station still had sufficient accuracy and availability,and some mesoscale and microscale weather systems could be observed on the wind plume graph.
