摘　　要：本文利用中国15个相近的雷达站和探空站的观测资料,用统计学方法检验VAD方法反演的风相对于探空风的偏差。分别对风速、风向进行检验的结果表明:VAD方法反演的风向对于探空风的风向偏差较小(23.0%),风速偏差略大(51.6%),VAD风风速通常比探空风风速小(平均为-10.3%)。本文还对比了多站探空风和多站VAD风组成的风场,结果表明二者的风场基本一致。The deviation between the wind data of radio-sounding system and the wind data of CINRAD retrieved by VAD method has been calculated by statistical methods.The result shows that the difference betwween the wind direction retrieved by VAD and sounding system is smaller（23.0%）,but the differrence of speed is bigger（51.6%）.The VAD retrieved wind speed is generally smaller than the sounding wind velocity（-10.3%）.The article also compared the wind field of multi-station VAD wind and wind field of multi-station sounding data.The results showed that both wind fields are basically the same.
