Automated Tropical Cyclone Forecasting System information
Software used to predict and forecast tropical cyclogenesis and to track tropical cyclones
This is how forecast model tracks appear within ATCF. This example is from 2006 Ernesto's first advisory. The NHC official forecast is light blue, while the storm's actual track is the white line over Florida.
The Automated Tropical Cyclone Forecasting System (ATCF) is a piece of software originally developed to run on a personal computer for the Joint Typhoon Warning Center (JTWC) in 1988,[1] and the National Hurricane Center (NHC) in 1990. ATCF remains the main piece of forecasting software used for the United States Government, including the JTWC, NHC, and Central Pacific Hurricane Center. Other tropical cyclone centers in Australia and Canada developed similar software in the 1990s. The data files with ATCF lie within three decks, known as the a-, b-, and f-decks. The a-decks include forecast information, the b-decks contain a history of center fixes at synoptic hours, and the f-decks include the various fixes made by various analysis center at various times. In the years since its introduction, it has been adapted to Unix and Linux platforms.
