The Weather Research and Forecasting ( WRF ) Model ( / ˈ w ɔːr f / ) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software for this. WRF features two dynamical (computational) cores (or solvers ), a data assimilation system, and a software architecture allowing for parallel computation and system extensibility. The model serves a wide range of meteorological applications across scales ranging from meters to thousands of kilometers.

20-618: A domain covering the continental United States. The Rapid Refresh is run at the NOAA National Centers for Environmental Prediction (NCEP). It is based on the framework of the Weather Research and Forecasting model (WRF); the Global Forecast System (GFS) provides the boundary parameters. The grid points are spaced every 13 kilometres (8.1 mi), with 50 vertical intervals extending up to
30-418: A flexible and robust platform, while offering advances in physics, numerics, and data assimilation contributed by the many research community developers. WRF is currently in operational use at NCEP and other forecasting centers internationally. WRF has grown to have a large worldwide community of users (over 30,000 registered users in over 150 countries), and workshops and tutorials are held each year at NCAR. WRF
40-489: Is a numerical weather prediction (NWP) model. The model is designed to provide short-range hourly weather forecasts for North America. The Rapid Refresh was officially made operational on 1 May 2012, replacing the Rapid Update Cycle (RUC). The model also serves as the boundary conditions for the higher-resolution High Resolution Rapid Refresh ( HRRR ) model, that uses a 3 km (1.9 mi) grid spacing on

60-693: Is supported to the community by the NCAR Mesoscale and Microscale Meteorology Laboratory. The WRF-NMM solver variant was based on the Eta model, and later nonhydrostatic mesoscale model, developed at NCEP. The WRF-NMM (NMM) is supported to the community by the Developmental Testbed Center (DTC). The WRF serves as the basis for the RAP and HRRR models : high-resolution operational forecast models run regularly at NCEP. The WRF also serves as
70-461: Is used extensively for research and real-time forecasting throughout the world. It has been shown to perform well in simulating Atmospheric convection , but to be prone to producing squall lines too easily. WRF offers two dynamical solvers for its computation of the atmospheric governing equations, and the variants of the model are known as WRF-ARW (Advanced Research WRF) and WRF-NMM (nonhydrostatic mesoscale model). The Advanced Research WRF (ARW)
80-773: The (then) Forecast Systems Laboratory (FSL)), the Air Force Weather Agency (AFWA), the Naval Research Laboratory (NRL), the University of Oklahoma (OU), and the Federal Aviation Administration (FAA). The bulk of the work on the model has been performed or supported by NCAR, NOAA, and AFWA. WRF allows researchers to produce simulations reflecting either real data (observations, analyses) or idealized atmospheric conditions. WRF provides operational forecasting
90-665: The basis for the North American Mesoscale (NAM) model at 12km and 3km grid resolutions. A version of WRF-NMM tailored for hurricane forecasting, HWRF (hurricane weather research and forecasting), became operational in 2007. In 2009, a polar optimized WRF was released through the Byrd Polar Research Center at the Ohio State University . Rapid Refresh (weather prediction) The Rapid Refresh ( RR or RAP )
