The '''weatherWeather researchResearch and forecastingffrecasting''' ('''WRF''') model<ref>{{Cite web|url=https://www.mmm.ucar.edu/weather-research-and-forecasting-model| title=WRF Model site}}</ref> {{IPAc-en|ˈ|w|ɔr|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.

The effort to develop WRF began in the latter part of the 1990s and was a collaborative partnership principally among the [[National Center for Atmospheric Research]] (NCAR), the [[National Oceanic and Atmospheric Administration]] (represented by the [[National Centers for Environmental Prediction]] (NCEP) and 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).<ref name="NCAR news release">{{Cite web|url=http://www.ucar.edu/news/releases/2006/wrf.shtml |publisher=NCAR |title=Weather Forecast Accuracy Gets Boost with New Computer Model |date=25 August 2006 |accessdate=27 June 2010 }}</ref> The bulk of the work on the model has been performed or supported by NCAR, NOAA, and AFWA.
