    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 ...

    An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).

    The ensemble variant of the GEM is known as the Global Ensemble Prediction System (GEPS). It has 20 members (plus control) and runs out 16 days, the same range as the American global forecast system. The GEPS runs alongside the GFS ensemble to form the North American Ensemble Forecast System. A regional ensemble prediction system (REPS ...

    The global models are run at varying times into the future. The Met Office's Unified Model is run six days into the future, [55] the European Centre for Medium-Range Weather Forecasts model is run out to 10 days into the future, [56] while the Global Forecast System model run by the Environmental Modeling Center is run 16 days into the future. [57]

    During this time, the AVN model was extended to the end of the forecast period, eliminating the need of the MRF and thereby replacing it. In late 2002, the AVN model was renamed the Global Forecast System (GFS). [29] The German Weather Service has been running their global hydrostatic model, the GME, using a hexagonal icosahedral grid since ...

    The WRF replaced the Eta model on June 13, 2006. [1] The NAM is run four times a day (00, 06, 12, 18 UTC) out to 84 hours, with 12 km horizontal resolution and with three-hour temporal resolution, providing finer detail than other operational forecast models. Its ensemble is known as the Short Range Ensemble Forecast (SREF) and runs out 87 hours.

    The Weather Research and Forecasting (WRF) Model [1] (/ ˈ w ɔːr f /) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs, developed in the United States. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software ...
