中文摘要: 以L波段探空雷达探测到的水平风为标准对全国风廓线雷达探测到的水平风的可信度进行评估，得到：风廓线雷达探测到的水平风在700 hPa高度以下与L波段探空雷达测风有较好的一致性；并且将风廓线雷达探测到的垂直速度与同址地面自动气象站观测到的1 h雨量进行相关性分析，得出垂直速度大小能很清楚地反映降水的开始、结束以及降水的强度；最后将全国风廓线雷达探测到的水平风进行组网对比分析，得出全国风廓线雷达探测得到的水平风在700 hPa高度下是可信的，风向可信度随探测高度的增加而增大，风速可信度随探测高度的增加而降低。

中文关键词: 风廓线雷达网，水平风场，垂直速度

Abstract:This paper firstly uses the horizontal wind data detected by radiosonde as a standard to assess the credibility of the horizontal wind observed by wind profiler (WPR), finding that the horizontal wind observed by the national wind profiler under 700 hPa height has a good consistency with that of radiosonde. Secondly, the correlation analysis on the vertical speed got by the wind profile and the one hour rainfall observed by the same address ground automatic meteorological station (AMS) reveals that the vertical velocity magnitude can clearly reflect the onset, end and precipitation intensity of a rainfall event. Finally, comparative analysis on horizontal wind data from the national wind profiler network is carried out, and the results show that horizontal wind observed by wind profiler at 700 hPa height is credible, the credibility of the wind direction increases with the increase of probe height, and the wind speed credibility decreases with the increase of probe height.
