The GFS was the most skillful single track model for the 2021 Atlantic hurricane season at all lead times, and its ensembles are much improved relative to previous iterations.
An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).
The first dynamical hurricane track forecast model, the Sanders Barotropic Tropical Cyclone Track Prediction Model (SANBAR), [9] was introduced in 1970 and was used by the National Hurricane Center as part of its operational track guidance through 1989. It was based on a simplified set of atmospheric dynamical equations (the equivalent ...
This image shows the morning GEFS ensemble, which includes multiple runs of the American GFS computer model, for invest 98 on September 21, 2022. The black line in the center is the ensemble mean ...
Along with the NWS's Global Forecast System (GFS), which runs out to 16 days, the ECMWF's Integrated Forecast System (IFS), which runs out 10 days, the US Naval Research Laboratory Navy Global Environmental Model (NAVGEM), which runs out eight days, the UK Met Office's Unified Model, which runs out to seven days, and Deutscher Wetterdienst's ...
The hurricane center also said additional strengthening is forecast, and Helene is expected to become a hurricane on Wednesday. Thereafter, the storm is expected to continue to strengthen ...
Ahead of the 2003 Pacific hurricane season, the NOAA forecasters decided to start issuing an experimental tropical cyclone outlook for the Eastern Pacific, which was designed not to be updated during the mid-season. [5] As a result of both the 2003 and 2004 outlooks being successful, the predictions became an operational product during 2005. [6]
The Atlantic hurricane season runs from June 1 through Nov. 30. The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of Mexico. Stay informed.
