2009年6月5日灌南县一次强对流天气过程分析

Analysis of the Severe Convective Weather Process Occurred in Guannan County on June 5, 2009

利用各种常规（探空）和非常规（自动站）资料对2009年6月5日灌南县的一次强对流天气过程进行了分析，结果表明：500hPa冷平流和850hPa暖平流增强了大气层结的不稳定性；地面冷锋和700hPa切变线触发了不稳定能量的释放；强对流天气发生在700hPa（前倾）槽和地面锋线之间的区域。

By using conventional sounding data and the automatic meteorological station records, the severe convective weather occurred on 5th June 2009 in Guannan county are analyzed. Results showed as follows： 500 hPa cold advection and 850 hPa warm advection enhanced the instability of the atmospheric stratification; the ground cold front and 700 hPa shear line triggered the release of unstable energy; severe convective weather occurred in the region where is between 700 hPa forward slot and the ground front line.
