The tropical cyclone formation probability (TCFP) is determined by NCEP global forecasts, Reynolds weekly sea surface temperature, and GOES-East, GOES-West, MTSAT-1R and Meteosat-7 channel-3 (water vapor) imagery. These data points are used as input to an algorithm and then calculates an estimate of the probability for possible tropical cyclone formation within 500km of each grid point within the next 48 hours.

TCGI is a disturbance-following statistical model to provide forecasters with an objective tool for identifying the 0-48hr and 0-120hr probability of TC genesis in the North Atlantic and East Pacific basin based on satellite and GFS forecasts.

EGGI builds on the success of TCGI and expands to global basins as well as incorporating the 30 ensemble members of the NCEP GEFS, utilizing non-linear Machine Learning Tools (e.g. Random-forest, k-nearest neighbors) to classify TC genesis occurrence in forecast fields.
