The Weather Research and Forecasting model is a mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting applications.

It features two dynamical cores, a data assimilation system, and software architecture supporting parallel computation and system extensibility. The model serves a wide range of meteorological applications across scales from tens of meters to thousands of kilometers.
