An early prototype of the Weather Research and Forecast (WRF) model is now available and contains options for parameterization of 3-d turbulence and diffusion, vertical turbulent trnasports in the planetary boundary layer, long- and short-wave radiation, deep cumulus convection and cloud and precipitation microphysics. With the near-future addition of a land-surface scheme, the model can be considered a full-physics model, albeit a bare-bones one.

In our presentation, we summarize current satus of physics in WRF, and routes we desire to take to bring the physics in WRF to a state-of-the-art level. In the process, we also identify topics we believe need strong research emphasis, and outline possible strategies for evaluating various 'suites' of physics schemes.
