The CWRF has been developed on the basis of the Weather Research and Forecasting (WRF) model by incorporating numerous improvements that are crucial to climate scales, including interactions between land-atmosphere-ocean, convection-microphysics and cloud-aerosol-radiation, and system consistency throughout all process modules. The CWRF improvements have been accomplished through iterative, extensive model refinements, sensitivity experiments, and rigorous evaluations over the past 8 years. As a result, the CWRF has demonstrated greater capability and better performance in simulating the U.S. regional climate than the existing CMM5 (Climate extension of the MM5) and the WRF. This presentation will provide a general model description and basic skill evaluation over the U.S as compared with other regional climate models. The emphasis will be on elaboration of the advanced physics parameterizations that are developed for CWRF to improve weather forecasts or climate predictions. Other CWRF capabilities and applications for climate change impacts will be discussed. The CWRF also provides a unique modeling platform for education and research of graduate students.
