| 摘 要： | 利用长江中下游外场实验的多普勒雷达联合观测资料，检验使用VAP（Velocity-Azimuth Process）方法反演中-β尺度（20～200km）水平风场的可靠性。局地均匀风假定的合理
性分析表明，在125km以内VAP方法反演的水平风场的分辨率可以满足中-β尺度(20～200km)分辨率的需求。多种方式检验表明，单多普勒雷达VAP方法反演出的水平风场可以正确地反映风场中的中-β尺度结构，作为分析中尺度风场信息的依据。

| Abstract: | Tests were presented for detecting the reliability of meso-β scale (20～200km)wind field retrieved from single Doppler radar by VAP (Velocity Azimuth Process) algorithm using the data observed by dual Doppler radar. The analysis of the assumption of homogeneous regional wind showed that the resolution of wind field retrieved by VAP algorithm could meet the requirement of analyzing the meso-β scale weather system. The tests with different kinds of methods showed that the wind field retrieved by VAP algorithm could get the structure of meso-β scale wind field correctly, and could be used to analyze the meso-β scale wind field. |
