NOAA is about to make some big changes to its global weather model

Recommended Posts


The nation's weather and climate organization, NOAA, has appointed a new director of its Environmental Modeling Center. This position essentially oversees development of the US computer models used to forecast weather around the world. The new director is Brian Gross, who fortunately has extensive experience in the field, having worked at NASA and led NOAA's prestigious Geophysical Fluid Dynamics Laboratory.

Gross becomes the full-time leader of NOAA's modeling center at a critical time. The organization is about to substantially change the dynamic core, or engine, of its primary weather model—the Global Forecast System. This GFS model provides the foundation of many, if not most, seven- and 10-day forecasts that consumers see on their weather apps or in the nightly news. It also provides critical forecasts for hurricane tracks and other significant weather around the world.
