Why use a dynamical regional model?
Historically, attempts to study the relationships between global warming and hurricanes with dynamical rather than statistical models have been undertaken with either global climate models that are easily criticized as having too coarse a resolution to convincingly resolve hurricanes, or very high resolution models of individual storms with which one cannot address questions of storm freqeuncy. Our work is distinctive in the high resolution (18km) that we are able to use by restricting the domain to that of the Atlantic only. (There is an important global model of comparable resolution described in the literature — Oouchi et al. (2006) , which we comment on below.) Balancing the advantage of more easily moving to finer resolution, this regional approach has disadvantages as well. In particular, we need to rely on global models to provide input into our regional model when we predict the future. We would prefer to work with high resolution global models, and are pursuing global simulat
