Abstract
Understanding tropical cyclone (TC) climatology is a problem of profound societal significance and deep scientific interest. The annual cycle is the biggest radiatively-forced signal in TC variability, presenting a key test of our understanding and modeling of TC activity. TCs over the North Atlantic (NA) basin, which are usually called hurricanes, have a sharp peak in the annual cycle, with more than half concentrated in only three months (August to October), yet existing theories of TC genesis often predict a much smoother cycle. Here we apply a novel framework originally developed to study TC response to climate change in which TC genesis... more
