| 摘 要： | 通过对2005年5月30日庆阳市区域性冰雹天气西峰新一代天气雷达回波资料的分析,得到了冰雹云在新一代天气雷达强度回波、速度回波和物理量产品中的特征,揭示了这次区域性冰雹是低涡底部切变线造成的,庆阳市区的特大冰雹并不是带状冰雹云系移动到当地产生的,而是飑线移动中在庆阳市区产生超级单体风暴造成的。

| Abstract: | Based on the analysis of Xifeng new generation weather radar echo data of regional hail weather on 30 May 2005 in Qingyang city,the hail cloud characteristics in new generation weather radar intensity echo,velocity echo and physical quantity products were given out.Results show that the shearline at the bottom of the low votex resulted in this hail weather,and it was not the zonal hail cloud moving to Qingyang city but the supercell hail cloud forming over the city in the moving course of the squall line that caused this strong hail event. |
