Abstract Using a microwave radiative transfer (MWRT) model with microwave brightness temperatures (TBs) observed from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI), an indirect approach evaluated hydrometeors generated from the Weather Research and Forecasting (WRF) model in the process of CHABA typhoon in August 2004. This study compares the simulated TBs generated from the microwave radioactive transfer model connected to the WRF model with the observed TBs derived from TMI and analyzes the differences between these TBs. The results indicate that the WRF model underestimates the amount and area of liquid and ice hydrometeors inside the typhoon center. The results also indicate relatively better agreement between the simulated and the observed TBs in the vertical polarization than in the horizontal polarization.
