Dynamical Studies in Hurricane Intensity Change.
Abstract
My research objective is to objective to elucidate and quantify a variety of dynamical processes believed important in hurricane intensity change. As a continuation of my collaboration with scientists at the Hurricane Research Division in Miami, the asymmetric stability problem for rapidly rotating vortices has recently been examined within the framework of asymmetric balance (AB) theory. In this paper the theorem of Charney and Stern is generalized to cover rapidly rotating (i.e. large Rossby number) baroclinic vortices. The theory is applied to observational data from hurricane Gloria of 1985, and Gloria is shown to satisfy the necessary condition for exponential instability. In order to determine whether such instabilities are realized and what role they may play in intensification cycles of hurricanes, a complete eigenvalue analysis is planned for the upcoming year
