营口地区一次暴雨天气过程分析

An analysis of heavy rain process in Yingkou Area

本文利用高空与地面气象资料、探空资料、卫星云图、雷达产品和EC等资料对2014年8月22日至25日营口地区暴雨过程的天气尺度系统、中尺度系统进行了分要素分析,结果表明高低空形式的配合和各种物理量条件均有利于本地区暴雨的形成,同时各种数值预报中EC预报准确率较高。

In this paper,the weather-scale system and mesoscale system of the rainstorm process in Yingkou area from August22to August25,2014were analyzed by factor analysis using the data of upper-air and ground meteorological data,sounding data,satellite image,radar product and EC.The results show that the combination of high and low altitude forms and various physical quantities are conducive to the formation of heavy rain in this area.Meanwhile,the accuracy of EC prediction in various numerical predictions is high.
