Weather Research and Forecasting (WRF) Model

The Weather Research and Forecast Model (WRF) is a next generation mesoscale forecast model and assimilation system that has advanced both the understanding and prediction of mesoscale precipitation systems. The model incorporates advanced numerics to solve the governing equations, advanced data assimilation techniques, a relocatable multiple grid nesting capability and improved physics particularly for the treatment of convection and mesoscale precipitation. It is intended for a wide range of applications, from idealized research to operational forecasting, with a priority emphasis on horizontal grids of 1-10 km.

Current numerical prediction models predominantly use a single physics package and a single numerical scheme; no options are available within the model. The WRF physics package is intended to be plug compatible to allow easy exchange of physics packages with other models. At least one representative package for each of physical processes necessary for mesoscale forecasts is included.

WorldWinds used WRF to forecast winds in the wake of the Deepwater Horizon Oil Spill in order to predict the surface movement of oil plumes forced by the winds.  As well, WorldWinds has helped configure and optimize WRF to run on client HPCC’s for various research and operational activities.
