| 摘 要： | 利用常规地面、高空观测资料和梧州S波段新一代天气雷达探测产品资料,对2012年4月12日夜间发生在贺州市的一次致灾冰雹天气过程的成因及雷达回波特征进行诊断分析,结果表明:在高空槽、低层切变线和地面冷空气共同影响的中小尺度天气环流背景下,配合高空干冷、低层暖湿的不稳定大气层结是这一次降雹天气过程产生的主要原因。此次降雹天气过程在多普勒雷达回波图上呈现出典型的超级单体风暴特征。

| Abstract: | Basing on surface and aerial conventional observation,the data of new generation S bands weather radar of Wuzhou city,the hail disaster weather process occurred on the night of April 12,2012 in the city of Hezhou was analyzed.The results show that under the combined effect of upper trough,low-level shear line and the ground cold air,the unstable atmospheric stratification with cold and dry in upper-level,warm and moist in low-level is the main reason for the hail weather process.In the Doppler radar echo images,it displays the typical characteristics of a super-cell storm. |

| Keywords: | local convection upper-level dry and low-level wet physical quantity analysis super-cell storm |
