Abstract
By matched asymptotic expansions we analyze the simplified threedimensional atmospheric flow regime of a nearly axisymmetric vortex in dry air that is in gradient wind balance and embedded in a quasigeostrophic background wind with weak vertical shear. A description of the vortex' overall motion, its vertical tilt, and of the evolution of its leadingorder axisymmetric core structure are developed. The analysis includes the influence of diabatic source terms in the vortex core as a first step towards an asymptotic theory for the structure and motion of hurricanes. The theory is closed except for the solution of a regularized quasigeostrophic outer flow problem, the formulation of which is outlined here but whose detailed description and numerical integration are deferred to future work.
