多普勒天气雷达垂直风廓线(V WP )产品在业务预报中已有较广泛的应用,并得到了风廓线的某些特征结构与雷暴及强对流之间的对应关系。由于对多普勒径向速度反演得到风廓线产品的VAD算法缺乏了解,目前对VWP 及速度方位显示(VAD)产品的应用还存在一些误区。文章由单多普勒雷达反演水平风场的基本原理入手,回顾了VWP 及VAD产品在暴雨与强对流临近预报中的应用,并重点对VWP及VAD产品的业务应用误区进行了讨论。
多普勒天氣雷達垂直風廓線(V WP )產品在業務預報中已有較廣汎的應用,併得到瞭風廓線的某些特徵結構與雷暴及彊對流之間的對應關繫。由于對多普勒徑嚮速度反縯得到風廓線產品的VAD算法缺乏瞭解,目前對VWP 及速度方位顯示(VAD)產品的應用還存在一些誤區。文章由單多普勒雷達反縯水平風場的基本原理入手,迴顧瞭VWP 及VAD產品在暴雨與彊對流臨近預報中的應用,併重點對VWP及VAD產品的業務應用誤區進行瞭討論。

Doppler weather radar VAD wind profile (VWP)products are widely used in operational fore-cast,and the corresponding relations between the wind profile structure characteristics and the thunder-storm,and severe convection have been achieved.Not knowing much about the VAD algorithm of wind profile products which are got by retrieving the radial velocity of Doppler radar,there are still some errors in using VWP and velocity azimuth display (VAD)products.In this paper,based on the basic principle of single Doppler radar wind field retrieval,VWP and VAD products applications in heavy rain forecasting and severe convection nowcasting are reviewed,and operational application errors of VWP and VAD prod-ucts are emphatically discussed.
