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.
