Each card on this page represents a model used or developed by the SPoRT program. The model on a green card, marked as "Evaluation Product," is being used by at least one National Weather Service Forecast Office. Models on blue cards, marked as "Research," are still in development, or exist mainly for academic purposes. For more background on a model, click the link at the bottom right of the card.

The Weather Research and Forecasting (WRF) model is a next-generation mesoscale numerical weather prediction system designed to serve operational forecasting, atmospheric research, parameterization research, and coupled-model applications. All of these types of activities are ongoing at the SPoRT Center (see above). The WRF model has two dynamic cores: the Advanced Research WRF (ARW) and Nonhydrostatic Mesoscale Model (NMM). The system is designed to be portable, efficient, and available for parallel computing platforms. Applications with scales ranging from meters to thousands of kilometers are supported, and the system allows a user to easily run nested grids for high-resolution forecasting. Additionally, WRF contains multiple physical parameterization options that can be selected depending on the application, grid resolution, and even the weather of the day.
