| 摘 要： | 在WRFDA-3DVar（Weather Research and Forecasting model's 3-dimensional variational data assimilation）的框架下，添加了新的探测器AMSR2（Advanced Microwave Scanning Radiometer 2）微波辐射率资料的同化模块，实现了AMSR2辐射率资料在中小尺度同化系统中的有效使用。台风"山神"（Son-Tinh）直接同化AMSR2资料的个例试验结果表明，AMSR2资料可以很好的探测出台风的形态，并且与没有同化该资料的控制试验相比，同化AMSR2辐射率资料可以有效提高模式分析场的质量，进一步提高了台风中心气压，最大风速和台风路径的预报。

| 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. |
