单多普勒雷达资料在伴随模式同化系统中的应用研究
A Study of Single-Doppler Data Assimilation in Adjoint-model Assimilation System
-
摘要: 利用变分方法反演单多普勒雷达资料,得到风矢量场。同时,利用MM5伴随模式同化系统,结合一次暴雨过程,设计四种方案,进行数值模拟试验。结果表明,通过变分方法反演的雷达资料的应用对于暴雨的分布预报有明显的改善作用;运用伴随方法Abstract: In this context conventional and non-conventional observations(Single-Doppler Data) are assimilated by MM5 adjoint-model assimilation system so as to do research on the role of Single-Doppler Data in improving th
