This animation shows winds over the western United States between 20 October 2019 and 28 October 2019. The strongest gusts appear bright yellow; weaker winds are purple. The wind data comes from the Goddard Earth Observing System Model 5 (GEOS-5), an experimental weather model that scientists at NASA use to analyze global weather phenomena. The GEOS model ingests wind data from more than 30 sources, including ships, buoys, radiosondes, dropsondes, aircraft, and satellites. Video: Joshua Stevens / Lauren Dauphin / NASA Earth Observatory
