摘要
“我国重大气候和天气灾害的形成机理与预测理论研究”项目首次启用双多普勒雷达组网同步观测 ,如何从同步观测的暴雨资料中反演三维风场 ,具有重要的理论和现实意义。根据项目需要 ,建立了国内首套多部多普勒天气雷达同步探测三维风场反演软件系统 ;并反演出 2 0 0 1年 7月 1 3日由双多普勒雷达同步观测到的一个中 β尺度暴雨系统的三维风场 ,结果显示 ,该三维风场结构合理 。
″973″key project--China Heavy Rain Experiment and Study (CHeRES) used dual-Doppler radar to measure the heavy rain in the middle and lower reaches of Changjiang River in 2001,it is the very important to retrieve the three-dimensional wind fields using the radar volume scan data. A software system is developed that can retrieve the three-dimensional wind fields from the data measured by multiple-Doppler radar synchronously. The three-dimensional wind fields of a meso- β heavy rain measured by dual-Doppler radar on July 13th 2001 are retrieved and analyzed by using this software system. The results show that the wind field structure is resonable,and the system can meet the requirements of the experiment.
