摘要:

利用NCEP 1967 ~2000年再分析高空格点资料,分析了大到暴雨当时场高低空环流气候背景特征。并在此基础上根据经验及统计相结合的方法进行模拟拟合,分月建立了大到暴雨3种类型(西高东低、平直或波动、西低东高)的高低空环流气候模型及距平差值场,从而为以后分析预报成
因、建立预报因子库及短期预报建摸奠定了基础。

关键词: 大到暴雨, 环流特征, 分型方法

Abstract:

 Based on the reanalysis data of the upper air grid point from NCEP during 1967一2000,the(harac;teristi<、of both upper and lower air(irc;ulation(urgent fields under the(ondition of heavy or torrential rains were analyzed and the(limatic; models of three upper and lower air(irc;ulation patterns and their departure difference fields were established month by month in May to September by experience and statistical method.  Thus the essential theoretical foundation for analyzing weather forecast result establishing predicting factors data and setting up the model of short range forecast has been provided

Key words:  heavy or torrential rain, circulation characteristics , classification
