ECMWF is an intergovernmental organisation that produces medium-range and seasonal weather forecasts for Europe and the world. It operates one of the largest supercomputer complexes and the world's largest archive of numerical weather prediction data.
The Integrated Forecast System (IFS) is a global numerical weather prediction system developed by ECMWF and Météo-France. It has different configurations and resolutions, and is used by many national weather services and research institutions.
Even the world’s most powerful computers can’t say precisely where the Category 5 storm is headed for landfall when it hits the U.S.
GEM is a Canadian weather forecasting and data assimilation system that runs out to 16 days. It has different variants for global, regional and mesoscale applications, and uses a hydrostatic primitive equation with a terrain following pressure coordinate.
ERA-15 is the first reanalysis product by the European Centre for Medium-Range Weather Forecasts (ECMWF), covering 15 years from December 1978 to February 1994. It uses various sources of meteorological observations and a 125 km resolution model to improve historical weather maps and analysis.
The ECMWF model, the Ensemble Prediction System (EPS), [8] uses a combination of singular vectors and an ensemble of data assimilations (EDA) to simulate the initial probability density. [9] The singular vector perturbations are more active in the extra-tropics, while the EDA perturbations are more active in the tropics.
Also known as spaghetti plots, these models show where a tropical system, such as a hurricane, may go. The more they are clustered together, the higher the confidence in the forecast.
NAVGEM is a numerical weather prediction computer simulation run by the US Navy. It produces weather forecasts for up to 180 hours and is one of five synoptic scale medium-range models in general use.
