Abstract

Abstract:

On the basis ofdaily observation data and products ofnumerical forecast, two cold waveweather cases occurred inwinter of 2008-2009 in Ningxia region were discussed by using synoptic analysismethod and combining cold wave forecast index in winter of Ningxia, including the circulation background, the influence system, synoptic formation cause, ect. Themajor features and formation causes of two cold wavewere revealed, and some instructive information about cold wave forecast in winter in Ningxia region was obtained.

Key words: cold wave, formation cause, forecast index

摘要：

利用常规天气资料和数值预报产品,应用天气学分析和诊断方法,结合宁夏冬季寒潮预报指标,对2008~2009年冬季2次寒潮天气从天气实况、环流背景、影响系统、天气成因等方面进行了对比分析。揭示了宁夏冬季2次寒潮天气的主要特点和成因,得到了一些宁夏冬季寒潮预报的指示信息。
