The leading mode of coupled Atlantic variability may unify a number of previously documented hurricane–climate relationships, and offers a more complete picture of hurricane variability than SST alone. Recent literature has been refocusing on the association between tropical North Atlantic Ocean sea surface temperature (SST) and Atlantic hurricane activity. Emanuel (2005) demonstrated this relationship using a power dissipation index (PDI), which depends on storm intensity and the lifetime of each storm over each hurricane season. Emanuel’s SST time series was calculated as an average over a large region (6°–18°N, 20°–60°W) of the tropical Atlantic. He found that the Atlantic
