The '''Weather Research and Forecasting''' ('''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.
