Global Ensemble Forecast System (Atmos Mean GEFS)

GribStream Code: gefsatmosmean

Description

The Global Ensemble Forecast System (GEFS) is a probabilistic weather prediction system managed by NOAA. It utilizes multiple ensemble members to generate a range of possible outcomes, enhancing the ability to assess weather uncertainties and probabilities. The ensemble approach helps to capture the range of possible weather scenarios by running slightly different initial conditions or model configurations, which are referred to as ensemble members or components.

The GEFS Atmos Ensemble Mean is a statistical aggregation of all atmospheric ensemble members, providing a single, representative forecast from the GEFS system. This mean forecast smooths out the variability inherent in individual ensemble members, offering a balanced and reliable view of expected atmospheric conditions such as temperature, wind, and precipitation. The ensemble mean is commonly used as a baseline in risk management, operational planning, and research, giving users a robust and stable prediction while still acknowledging underlying forecast uncertainties.
