A New Retrieval Technique for Single-Doppler Radar
-
摘要: 基于一些发展较强的中小尺度天气系统往往与风场的旋转或辐合、辐散有关的事实，文章提出了一种单部多普勒天气雷达径向风场反演二维水平风场的新方法，即涡度-散度方法。文中对1994年7月12日的个例进行了反演处理，处理结果与天气实况进行了对比分析，认为该方法不失为一种具有实用价值的单部多普勒雷达反演水平二维风场的方法。Abstract: This paper presents a new method called Vorticity-Divergence method (V-D method) for retrieving horizontal wind field from single-Doppler radar PPI. Retrieval experiments are conducted using the Doppler radar observational data on July 12, 1994 with the V-D method. The results are compared with the actual synoptic situation. It is shown that the V-D method is a effective one for the single-Doppler radar wind field retrieval
