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。
Impacted by the supercell storm whose life span continued for about 4 hours, the peculiar hail Weather process occurred in the east of Anhni province from the night of June 14th to the wee hours of June 15th 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.
