The resulting model, initially developed under the name FV3GFS, inherited the GFS moniker, with the legacy GFS continuing to be run until September 2019. [11] [12] Initial testing of the FV3-based GFS showed promise, improving upon the large-scale prediction skill and hurricane track accuracy of the legacy GFS. [13]
Trackwise, the GUNA model is a consensus of the interpolated versions of the GFDL, UKMET with quality control applied to the cyclone tracker, United States Navy NOGAPS, and GFS models. The version of the GUNA corrected for model biases is known as the CGUN. The TCON consensus is the GUNA consensus plus the Hurricane WRF model.
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.
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 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 ICON ...

The hurricane center uses only the top four or five highest performing models to help make its forecasts. If path tracker and spaghetti model are not displaying on your screen, you can view them here.
Of the United States forecasting models, the best performing model for tropical cyclone rainfall forecasting is known as the GFS, or Global Forecasting System. [17] The GFDL model has been shown to have a high bias concerning the magnitude of heavier core rains within tropical cyclones. [ 18 ]
As at least one model had predicted this week, the center's current forecast calls for the hurricane to make a small loop in the Gulf as it meanders through Monday. ... Hurricane Rafael path tracker.
