Abstract

The large-scale vortex structures that are commonly observed both in the oceans (e.g. Gulf Stream rings) and in the atmosphere (hurricanes, cyclones, Jupiter’s Great Red Spot) are in good approximation two-dimensional (2D), due to the combined eff ects of geometrical confi nement (essentially, the oceans and atmosphere are thin fl uid shells), density stratifi cation, and planetary rotation. Th eir dynamics is governed by conservation of potential vorticity, which is here defi ned as PV=(f+¿)/H, with f the Coriolis parameter (=2Osin f, with O the planetary station speed, f the geographical latitude), ¿ the local relative vorticity, and H the local layer depth (column height).
