摘  要:
利用常规气象资料、雷达回波资料及卫星云图等,分析了2009年6月5日连云港市发生的一次全市范围的雷雨大风及局部冰雹天气过程。结果表明,东北低涡后部冷空气入侵激发不稳定能量释放;该过程发生的动力特征并不明显,主要是由热力特征造成的;强回波带前沿更有利于产生大风;中尺度辐合线是这次过程的主要触发系统;雷达回波资料和卫星云图很好地反映出雷雨大风天气发生发展的全过程,为人们监测天气变化,提前做出预警服务提供了重要参考。

摘  要:
By dint of the regular meteorological information,radar information and satellite images and so on,this paper analyzes the process of a thunderstorm and local hail weather on June 5,2009 in Lianyungang. The results show that:The cold air in the rear of northeast vortex stimulates the release of unstable energy; Dynamic characteristics of this process is not obvious,mainly caused by the thermal characteristics; The cutting-edge of strong echo is more favorable to produce wind; Mid-scale convergence line is the main trigger system of this process; Radar echo information and satellite image well reflect the whole development process of this thunderstorms,and provide important reference for monitoring changes in the weather and early warning services for us.
