Fig. 2: ROC of the VarEPS forecasts for TC genesis during the period 2007-2010. Colour-coded dots correspond to VarEPS TC
genesis probabilities ranging from 0 to 100%. (a) ROC is determined as a function of forecast days in advance using a 48-hour
window on the date of TC genesis. (b and (c) Similar to (a), except for a 96-hour and 360-hour time windows.
