中文摘要: 本文利用华东中尺度天气试验资料,分析了系统性雷暴过程中逐时地面物理量场的变化。结果表明,θse、divv场与雷暴活动关系密切;在其不同发展阶段,它们具有不同的中尺度扰动特征;这些特征对天气的短时变化有一定指示意义。在此基础上,我们概括出了华东地区强对流天气发展四个阶段的概念模式。所得结果对于认识这类中尺度扰动和临近预报是有益的。

Abstract:The change of hourly surface physical parameter fields during the process of severe thunderstorm is analysed in this paper, using the data obtained from Eastern China Meso-scale Weather Experiment. Results of the study show: there exist an immidiate relation between the fields of θse,divv and the activities of thunderstorm, the characteristics of meso-scale turbulence are different at various stages of weather development, they have certain indicative meanings for the weather change during short period. In the basis of this analysis, we have proposed a conceptual model for the four stages of development of severe convective weather, in Eastern China, Results obtained were of benefit to understanding such meso-scale turbulence and nowcas-ting of severe convective weather.
