Nonhydrostatic, three-dimensional perturbations to balanced, hurricane-like vortices. Part II: Symmetric response and nonlinear simulations

Nolan and Grasso offers the second part of a study on the dynamics of nonhydrostatic perturbations to dry, balanced, atmospheric vortices modeled after tropical cyclones that examine the stability and evolution of symmetric perturbations-particularly those that are induced by the wave-mean flow interactions of asymmetric perturbations with the symmetric basic-state vortex. In contrast with results from previous studies with initially two-dimensional or balanced asymmetric vorticity perturbations, asymmetric temperature perturbations are found to have negative effect on overall intensity.
