摘要： 应用1971~2000年长春气象站10月至次年3月的逐日降水量、气温资料以及相应的NCEP/NCAR再分析资料,通过对资料的统计分析,给出了确定长春市发生强冰雪冻害天气的标准;根据对36个历史个例的高低空环流形势的分析,建立了4 种强冰雪冻害的天气概念模型:冷涡型、深槽型、浅槽型、锋区平直型;进一步分析了长春市冰雪冻害天气的物理量场、要素场的特征。

Abstract: By the analysis on the daily precipitation and temperature of Changchun station during October to next march from 1971 to 2000,and respondedly NCEP/NCAR reanalysis data, the standard of the great weather process with ice-snow and cool disaster is proposed.Based on studying the upper and lower air circulation of 36 weather processes, four synoptic models are given.In addition, the physical parameter fields and normal parameter fields of those processes are researched.
