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.
