Nonhydrostatic, Three-Dimensional Perturbations to Balanced, Hurricane-Like Vortices. Part II: Symmetric Response and Nonlinear Simulations

Abstract

This paper is the second part of a study on the dynamics of nonhydrostatic perturbations to dry, balanced, atmospheric vortices modeled after tropical cyclones. In Part I, the stability and evolution of asymmetric perturbations were presented. This part is devoted to the stability and evolution of symmetric perturbationsparticularly those that are induced by the wave-mean flow interactions of asymmetric perturbations with the symmetric basic-state vortex.
