Drift velocity of radiating quasigeostrophic vortices

Because of the beta effect, quasigeostrophic monopole vortices propagate westward and excite Rossby waves. This wave radiation depletes the vortex energy, and causes cyclones to drift northward and anticyclones southward. Explicit solutions describing such radiating vortices are found by perturbatio...

Zusammenfassung:Because of the beta effect, quasigeostrophic monopole vortices propagate westward and excite Rossby waves. This wave radiation depletes the vortex energy, and causes cyclones to drift northward and anticyclones southward. Explicit solutions describing such radiating vortices are found by perturbation analysis.
