NOAA has deployed a new set of operational AI driven global weather prediction models making a major advancement in forecast speed, efficiency, and accuracy while using fewer computing resources.
Key highlights include the Artificial Intelligence Global Forecast System (AIGFS), the Artificial Intelligence Global Ensemble Forecast System (AIGEFS), and the Hybrid Global Ensemble Forecast System (HGEFS). Together, these models support faster forecast delivery, improved tropical cyclone track guidance, and better representation of forecast uncertainty by combining AI and physics-based approaches.
These efforts stem from Project EAGLE (Experimental AI Global and Limited-area Ensemble), a multi-year collaboration across OAR, NWS, academia, and industry to advance NOAA’s operational weather prediction capabilities. EPIC is a key member of this collaboration through the provision of software infrastructure and community engagement support. Full details on model performance and technical background are available in the official NOAA announcement.
