GEFS stands for Global Ensemble Forecast System.
The Global Ensemble Forecast System is a numerical weather prediction model that generates multiple sets or ensembles of weather forecasts to provide a probabilistic outlook of future weather conditions. It is widely used by meteorologists and climate scientists to predict weather patterns on a global scale.
The GEFS model works by initializing the current atmospheric conditions from numerous observations around the world and then running multiple simulations using slight variations in the initial conditions. This ensemble approach takes into account the inherent uncertainties in the atmosphere and provides a range of possible weather scenarios rather than a deterministic forecast. Each ensemble member represents a different possible future state of the atmosphere.
By comparing and analyzing the different ensemble members, meteorologists can assess the likelihood of specific weather events or patterns occurring. This probabilistic outlook allows forecasters to determine the probabilities of extreme events such as heavy rainfall, strong winds, or severe storms.
The GEFS provides not only short-range forecasts but also medium-range forecasts extending up to two weeks in advance. It helps meteorologists in making informed decisions and issuing timely weather advisories and warnings. The output from the GEFS model is used by various weather agencies, including the National Weather Service in the United States, to enhance their forecasts and provide advanced warning to the public, thereby improving preparedness and safety in the face of changing weather conditions.
