Read the article: Neighborhood-level wind forecasts are on the horizon

June 29, 2026

NSF NCAR researchers are leveraging the Derecho supercomputer to develop groundbreaking, neighborhood-scale wind forecasts down to a two-meter resolution. By pairing uncrewed aircraft observations with FastEddy—an advanced microscale model—scientists can simulate how real-time wind gusts and turbulence interact with local buildings and trees. This innovative use of computational resources deliv...
