Definition
The term, in context
AI-assisted draft · approved dataset
ECMWF AIFS ENS is an artificial-intelligence ensemble weather forecasting system that generates many perturbed forecast members from slightly varied starting conditions to represent the range of possible atmospheric outcomes. Because the underlying model is trained on historical data rather than solving the full physical equations of the atmosphere, it produces large ensembles of global forecasts using a fraction of the computing power required by conventional numerical weather prediction.
