多普勒雷达在南宁大雨预报中的应用

The Application Of Doppler Radar For Nanning Heavy Rain Forecast

通过对1999～2003年南宁市引进多普勒天气雷达以来43个大雨过程进行分析和总结,将天气形势和多普勒天气雷达资料相结合,以天气来向的角度,对各类型多普勒雷达回波的源地、生消影响关键区、径向速度场特征进行总结,建立了3种类型的南宁大雨天气概念模型.

This paper summarizes the source area of various types of Doppler radar echo,the emerge and disappearance influence essential area,the characteristic of radial velocity field by the angle of the coming weather system through conducting the analysis and the summary on Nanning 43 heavy rains processes during 1999~2003 Since the introduction of the Doppler weather radar,and establishes 3 types of Nanning heavy rain weather conceptual models.
