AB: The Weather Research and Forecast (WRF) model is a new model development effort undertaken jointly by the NCAR, NOAA, and a number of collaborating institutions and university scientists. The WRF model version 1.3, which still is at research stage in NMC/CMA, was installed on IBM SP2 machine in 2002. It ingests the global model T213 fields as initial field and boundary conditions every 6 hours. The comparison the different horizontal resolution between 20km and 5km shows that the model running with high horizontal resolution can catch much more mesoscale features. But the verification results show that performance of the 24 hours precipitation forecast is not good. Recently, the WRF-3DVAR was used, which was expected to promote the model performance. However, the system is not better than other operational system in NMC/CMA.
