中文摘要:在风场局地均匀方法(Equation of Continuity Combined Uniform Winds 简称 ECUW)的基础上,提出一种利用单部多卜勒雷达资料计算水平风场空间分布的调和方法,即将风场局地均匀假设、风场局地线性假设和连续性方程结合起来,计算一种理想情况下的水平风场,并将其结果同速度-方位角显示技术(VAD)的计算结果作了比较。

A NEW SCHEME FOR RETRIEVAL HORIZONTAL WIND OF STRATIFORM CLOUD SYSTEM
Abstract:Based on ECUM method (equation of continuity combined uniform winds), a harmonic scheme for the spatial distribution of horizontal wind is proposed to retireve horizontal wind from a single Doppler radar data. This scheme is based on the assumptions of the local uniformity and linearh equation of continuity to obtain an ideal wind field. The calculation results are found to be superior to those by velocity-azimuth display(VAD)method.
