Application of CWRF for Regional Climate Change Projection and Impact Assessment
Xin-Zhong Liang, Department of Atmospheric and Oceanic Science and the Earth System Science Interdisciplinary Center, University of Maryland.
The CWRF is developed as a Climate extension of the Weather Research and Forecasting model (WRF) by incorporating numerous improvements in representation of physical processes and integration of external (top, surface, lateral) forcings 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. As a result, the CWRF has demonstrated great capability and excellent performance in simulating the regional climate over the U.S. This presentation will focus the CWRF added values over the driving general circulation model outputs and possible impacts of the present-day model fidelity on future climate projection. It will also discuss the utility of CWRF for predicting climate anomalies and extremes, as well as regional impacts.
