AMSR2辐射率资料同化对台风“山神”分析和预报的影响研究
The Impact of AMSR2 Radiance Data Assimilation on the Analysis and Forecast of Typhoon Son-Tinh
摘要
Abstract
A new assimilation module of AMSR2 (Advanced Microwave Scanning Radiometer 2) radiance data was constructed in WRFDA-3DVAR (Weather Research and Forecasting model's 3-dimensional variational data assimilation).With this module,the impact of AMSR2 assimilation on the analysis and forecast of Typhoon Son-Tinh was evaluated.AMSR2 data is able to detect Son-Tinh's cloud band pattern.Compared to the experiment without AMSR2 assimilation,AMSR2 assimilation provided a better typhoon structure,and significantly improved the central sea level pressure,maximum wind speed and typhoon track forecasts.关键词
