双多普勒雷达风场反演技术在两次上海登陆台风中的应用分析
Application analysis of dual Doppler radar wind field inversion technology in two typhoons landing in Shanghai
摘要
Abstract
This article explores a method for locating typhoon centers near Shanghai using a dual Doppler radar wind field inversion technique based on three-dimensional variational data assimilation(3DVAR).Initially,the Region-based Recursive Doppler Dealiasing(R2D2)algorithm is employed to correct radial wind field deblurring for single radar.Subsequently,the two nearest Doppler weather radars are selected to collaboratively invert the gridded wind field using 3DVAR,and thus carry out high-frequency positioning of the typhoon center.The research results demonstrate that the 3DVAR dual radar wind field inversion method effectively captures the circulation structure of typhoons,while also featured by high spatiotemporal resolution and precise positioning.The typhoon positioning results derived from 3DVAR method have a small deviation from those provided by the Central Meteorological Observatory.关键词
