2020年7月18——19日南疆西部分散性强降水雷达特征研究

Radar Characteristics of Scattered Heavy Precipitation in Western Southern Xinjiang from July 18—19,2020

利用区域加密自动气象站逐时资料、多普勒天气雷达资料,分析了2020年7月18—19日南疆西部强降水站点的雷达特征。结果表明:此次过程中,弓状回波的出现伴随着此次短时强降水的发生,且强回波高度达6 km以上,2.4°仰角上强降水区存在幅合运动。

Using regional encrypted automatic weather station hourly data and Doppler weather radar data,the radar characteristics of heavy precipitation sites in western southern Xinjiang from July 18-19,2020 are analyzed.The results show that during this process,the appearance of the bow echo was accompanied by the occurrence of the short-term heavy rainfall,and the height of the strong echo was above 6 km,and there was a combined motion in the heavy rainfall area at the elevation angle of 2.4°.
