摘要
利用常规观测资料、天气图资料和雷达产品资料,分析了2007年7月29日出现在安徽芜湖地区的冰雹等强对流天气过程,结果表明:外部抬升力、水汽条件、不稳定层结等条件同时满足时,有利于强对流天气的产生。此外,冰雹天气在雷达反射率、速度、VIL图上都有明显的特征,可充分利用雷达资料及时做出临近预报和预警服务。
Based on the routine observation material, weather chart material and the radar product material, we analyzed the hail and severe convective weather process in Wuhu area on July 29, 2007. The results show that the severe convective weather occurs easily when the outer lifting power, the water vapor condition and unstable stratification all occurred at the same time. In addition, the hail weather has the obvious characteristic in the radar reflectivity, the speed, and the VIL chart. We can make promptly ap- proaching forecast and provide the warning service by fully using the radar material.
