The Climate-Weather Research and Forecasting (CWRF) model is a regional climate model developed by the Earth System Modeling (EaSM) at the University of Maryland. CWRF is a climate extension of WRF, inheriting all of its functionalities, while incorporating a comprehensive ensemble alternative physics representations. Careful effort was taken in the development of CWRF to ensure consistency in the interactions between land, atmosphere, ocean; convection and microphysics; and clouds, aerosols, and radiation, yielding improved forecast skill over WRF on climate time scales.
