GFS Ensemble Tropical Cyclone Track Normalized Spread

Robert Hart and Lindsey Day, Florida State University

This page plots GFS Ensemble (GEFS) mean forecast track, the normalized spread of that ensemble compared to a 2004-2011 GEFS climatology,
and the individual ensemble members contributing to that spread. More detailed documentation of this project can be found in the links below.
