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.
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 main American global forecast model, the GFS underwent an upgrade several years ago that improved its reliability for hurricane forecasts. The GFS and GFS Ensembles have struggled in the last ...
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 ...
Tropical cyclone forecasting is the science of forecasting where a tropical cyclone's center, and its effects, are expected to be at some point in the future. There are several elements to tropical cyclone forecasting: track forecasting, intensity forecasting, rainfall forecasting, storm surge, tornado, and seasonal forecasting.
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]
Also known as spaghetti plots, these models show where a tropical system, such as a hurricane, may go. The more they are clustered together, the higher the confidence in the forecast.
