Storm season mean genesis potential distribution during the Cenozoic era. a Early Eocene, b Late Eocene, c Late Oligocene, d Early Miocene, e Late Miocene, f Late Pliocene, and g today. The pink lines show the 26 °C isotherm. The cyan lines show the 70 m s−1 contour for potential intensity. The 26 °C isotherm is collocated with the boundary of regions with mean potential intensity of 70 m s−1 in the modeled present climate, but the isotherm that correlates with high potential intensity varies across climates. Storm season is defined as Aug–Sep–Oct for the Northern Hemisphere and Jan–Feb–Mar for the Southern Hemisphere. The units of genesis potential are events m−2 month−1(×10−13)
