摘要 采用改进的简化伴随模式对单站多普勒雷达资料进行三维风场反演。选取2004年7月18日发生在湖北天门、应城的强降水天气过程,利用武汉新一代天气雷达(CINRAD/SA)的原始资料进行风场反演。研究结果表明:运用该方法反演出的三维风场,体现了强降水系统的气流特征,有一定的可信度和准确性;由此分析中小尺度天气系统发生发展的演变规律,对短时强降水预报具有指导作用。 The advanced simple adjoint method is adopted to retrieve the 3-D wind field of the severe rainfall event in Tianmen city and Yingcheng city on 18th July 2004 from the single radar data of Wuhan CINRAD/SA( China New Generation Weather Rader System/S-band A-style ). Results show that the retrieved wind field is, to a certain extent, reliable and accurate. It will help short-time strong rainfall forecasting with analyzing the evolvement course of meso-micro scale weather system.
