Abstract: In order to study the impact of different observation data assimilation in numerical models, we use the WRF model to simulate a rainstorm of huaihe river basin by assimilating the microwave radiometer data AMSUA and AMSUB of NOAA satellite, conventional sounding data. Results show that the assimilation of AMSUA and AMSUB data can affect the precipitation forecast, its results of heavy rain was obviously better than control test in TS and ETS. The result of sounding data assimilaton test was the best in the heavy rain simulation , can improve the false and missing rate of heavy rain significantly.
