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 global models are run outwards to varying times into the future. The UKMET Unified Model is run six days into the future, [16] the European Centre for Medium-Range Weather Forecasts model is run out to 10 days into the future, [17] while the Global Forecast System model run by the Environmental Modeling Center is run 16 days into the future ...
The UKMET Unified Model is run six days into the future, [41] while the European Centre for Medium-Range Weather Forecasts' Integrated Forecast System and Environment Canada's Global Environmental Multiscale Model both run out to ten days into the future, [42] and the Global Forecast System model run by the Environmental Modeling Center is run ...
Forecast map for Sunday 12/8. ... For most, computer models such as the European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS) show the arrival of the heat in ...
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.

ECMWF aims to provide accurate medium-range global weather forecasts out to 15 days and seasonal forecasts out to 12 months. [11] Its products are provided to the national weather services of its member states and co-operating states as a complement to their national short-range and climatological activities, and those national states use ECMWF's products for their own national duties, in ...
