摘  要:
2005年6月14日夜到15日凌晨受1个生命史达4 h之久超级单体影响,安徽东部出现罕见的冰雹天气过程。该文利用多普勒雷达、卫星云图、MM5、地面遥测和高空天气图等资料分析,试图揭示该次冰雹过程的天气特征。结果表明:该次大范围风雹强对流天气系统是在东北低涡下,高空前倾槽与地面辐合线有利的大环流背景下,一个中尺度对流系统MCS影响所致。

摘  要:
Impacted by the supercell storm whose life span continued for about 4 hours,the peculiar hail weather process occurred in the east of Anhui province from the night of June 14~(th) to the wee hours of June 15~(th) of 2005.This issue was analyzed with the circumfluent field and weather impact system with the data such as Doppler weather radar data,surface observations,upper-air observations and satellite imagery.The result of the study indicated that this large area wind-hail strong convection weather system was aroused by one MCS and controlled by the northeast low vorticity.It was in advantaged large circumfluence background of upper-air pitch trough along with surface convergence line.
