都安一次特大暴雨过程卫星和雷达图像特征分析

Discussion on Fireworks Factory Lighting Protection of Cenxi County

利用彩色增强显示的卫星云图、雷达和自动气象站资料对2010年5月31日22时至6月1日11时都安县出现的特大暴雨进行分析,发现这次暴雨过程由2个强降雨阶段组成,造成都安县特大暴雨的原因是1个形成于滇黔桂交界处的低涡在南移过程中,低涡东边缘对流强烈发展,对流云团主体移过都安而产生了强降雨,对应着这2个强降雨阶段,在卫星云图上分析出是由2个对流云团前后移过所造成的,在雷达回波图上可分析出对流云团中又先后有多个对流单体移过都安县上空。

Using color enhanced display of satellite images,radar and automatic weather station（aws） data from 22 o＇clock in the May 31 to 11 o＇clock in the 1 June,2010,the rainstorm occurs in Duan county was analyzed.It indicates that the rainstorm process has the two stages.Corresponding to the two stages,the satellite images show two convective clouds had drifted across Duan county.In the radar e-choes images,it also shows that there are more convective cells in the convective clouds successively moving across the county.The strong development of the main convective clouds in the east edge of a low vortex which generated on the junction of Yunnan,Guizhou and Guangxi resulted in Duan heavy rainfall.
