A numerical exploration of the sensitivity of tropical cyclone rainfall intensity to sea surface temperature

It is commonly accepted that there is a monotonically increasing relationship between sea surface temperature (SST) and tropical cyclone intensity (as measured by maximum near-surface winds or minimum central pressure). This perceived relationship has been used to extrapolate the effects of climatologically warmer SSTs on tropical cyclones. These warmer SSTs are one of the consequences of doubled CO₂ predicted by climate general circulation models (GCMs). Very few investigations have actually critically addressed this SST-storm intensity relationship, however. In this paper, a limited area modeling study is used to explore the potential links between SST and tropical cyclone intensity. Previous work, including some observational data, is reviewed and its implications for the interpretation of the results given here is presented. -from Authors
