The Tropical Cyclone Genesis Index (TCGI)

The Tropical Cyclone Genesis Index (TCGI) was transitioned to operations at NOAA’s National Hurricane Center in 2014 and was designed to provide forecasters with an objective tool for identifying the 0-48hr and 0-120hr probability of TC genesis in the North Atlantic basin. Discussion will cover efforts and results from a follow-on NOAA Joint Hurricane Testbed project designed to improve and expand TCGI. These TCGI enhancements include testing of new predictors, varying predictor search areas, improving tropical disturbance forecast tracks that are used, and expanding TCGI to run in the eastern and central North Pacific. This poster will highlight the new TCGI scheme, as well as its skill at predicting TC genesis in the North Atlantic and Pacific during the 2015-2017 hurricane seasons.
