多普勒速度图暴雨判据和短时预报工具研究

On Heavy Rain Signature Recognition by Radar Velocity Images and A Nowcasting Utility

对 38 2 4- C波段全相参多普勒天气雷达 1 995～ 1 999年径向速度场资料中逆风区进行统计分析 ,认为近距离逆风区可成为暴雨短时预报的一个有参考价值的判据。并给出人机交互识别逆风区工具的设计和实现方法。

C full phase pulse Doppler weather radar velocity images are studied with Doppler weather radar observation during the period of 1995—1999. Adverse wind regions in Beijing area can be a heavy rain nowcasting recognition signature. The design and implement of an interactive recognition utility are given.
