摘要
利用云南省大理州12个气象站1980-2008年29a的逐日气象观测资料及MICAPS资料,根据天气学原理,分析统计出产生大理州区域性强降雨天气的主要影响系统为切变线、西南低涡、两高辐合区、孟加拉湾风暴、南支槽和西行台风低压等,并统计出强降水过程影响系统的发生频率,在此基础上对各种影响系统进行归纳总结,提炼出产生大理州区域性强降雨影响系统的主要环流特征和预报着眼点。
Based on the data of MICAPS and rainfall during 1980- 2008,by using methods of statistics and synoptic climatological analysis,the main synoptic system of regional heavy rainfall and its Characteristics were analyzed in Dali prefecture.The results show that the main synoptic system giving rise to heavy rainfall weather in Dali prefecture were shear line,Bengal Bay Storm,low vortex,convergence zone of two high- pressure south branch trough,westbound typhoon low- pressure and so on. In this paper,the occurrence frequency and the characteristics of influencing synoptic and their footholds for forecast goal were summed up.
