The human problem

Forecasters need reliable tools beyond research demonstrations.

ECMWF used its established physics-based forecasting system.

AIFS added machine-learned predictions to the operational toolkit.

AIFS began running alongside the physics-based IFS on 25 February 2025.

Forecast users gained an additional operational source of guidance.

Deployment is not a guarantee of superiority for every variable, place, or event.

Compare performance continuously and improve forecast use.
