Geophysical vortices are one the most famous subjects in geophysical fluid dynamics since, for example, they affect mixing properties in the oceans.
Geophysical vortices are unstable due to an inertia-gravity wave emission, know as the radiative instability
Investigate an effect of planetary rotation on the radiative instability of a columnar vortex in stratified fluids.
Numerical and asymptotic linear stability analyses.
The radiative instability is stabilized in the presence of both cyclonic and strong anticyclonic planetary rotations.
