几种不同资料在冰雹天气结构特征分析中的应用

Application of Several Different Data in Hail Synoptic Structure Characteristic Analysis

利用MM5模式模拟结果、多普勒雷达产品及中尺度加密自动站资料对2007年造成山东省临沂地区的2次局地冰雹天气的中尺度系统的结构特征作了分析。结果表明:多普勒天气雷达、MM5模式、中尺度加密自动站等资料可以在一定程度上反映出发生冰雹等强对流天气的中尺度系统的水平,立体结构特征以及它们发生、发展的演变规律,对于进一步研究中小尺度系统和提高短时、临近预报的准确率有一定的帮助。

The MM5 model simulation results, products of Dopplor radar and data of mesoscale encryption automatic station were used to analyze the structural characteristics of mesoscale system of 2 local hail in Linyi region in 2007. The results showed that they could reflect the level, the dimensional structure and the evolution rule of occurrence and development of the severe convective mesoscale system in a certain extent,which could make. some help for further study of meso-and micro-scale system and improve the accuracy of short-term weather forecast.
