Abstract

The evolution of eyeball-like, unstable vorticity rings produced in hurricane eyeballs due to the vertical stretching effect, was presented. To determine the end states of the instability and flow patterns of a hurricane, the initial conditions of the vorticity rings were studied. The numerical model used in the study was the f-plane version of the multigrid barotropic model (MUDBAR). The flow involving vorticity rearrangement near the center of the model domain was analyzed. It was observed that very wide rings of width 108 km or more showed azimuthal wavenumber 2 structures initially, but never broke up into individual vortices.
