Abstract:

The new generation weather radar echoes data of the strong rainstorm weather occurred on July 8, 2006 in Qingyang citywas analyzed. Results show that upper shearline resulted in thisweather event, and the difference in intensity, velocity echoes and physical quantity p roduction between the rainstorm and hailweather was not so obvious, but the damage was more severe. So for weather forcast, weather events like this should be focused, and the same way as hail supp ression shoud be adop ted to reduce p recip itation intensity and decrease damages.

Key words:  new generation weather radar, rainstorm, echo characteristic

摘要：

通过对2006年7月8日庆阳市1次强暴雨天气过程雷达回波资料的分析,得出在高空切变线影响下形成的强对流暴雨天气的雷达强度回波、速度回波和物理量产品中的主要特征与冰雹天气的差别并不明显,但天气现象差别较大,降水强度大,容易致灾;强雷暴特别活跃,容易发生雷击。因此在预报服务中应当引起重视,可以采取人工影响的方式降低其强度,减轻灾害损失。
