摘要
基于WRF-ARW和WRFDA3.8直接同化HDF5格式的AMSR2(Advanced Microwave Scanning Radiometer 2)卫星微波成像资料。利用2014-07-15~31的AMSR2数据进行质量控制和偏差订正试验,检验质量控制效果,重点分析统计所得偏差订正系数的应用效果;选择2014年第9号台风"威马逊(Rammasun)"作为研究对象,试验同化AMSR2资料对台风路径及强度预报的影响。结果表明,AMSR2微波成像资料对台风路径和强度预报效果均有改善。
Based on the WRF-ARW and WRFDA 3.8 version,this paper directly assimilates AMSR2（Advanced Microwave Scanning Radiometer 2）satellite microwave imaging data in HDF5 format,uses AMSR2 data during July 2014 from 15th to 31 st to do the quality control and bias correction tests and focuses on the analysis of the application effect of the bias correction coefficient.Selecting typhoon Rammasun（No.9in 2014）as the research subject,the effect of assimilating AMSR2 data on path and strength forecasting is verified.The results show that it improves the effect of AMSR2 microwave imaging data on typhoon path and intensity forecast.
