Testing the Limits of Surface QG Theory With Deep Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Surface Quasi‐Geostrophic (SQG) theory provides a closed‐form mapping from surface buoyancy to interior stream function under the assumption that interior potential vorticity (PV) vanishes (Q=0) $(Q=0)$. In realistic flows, however, the interior PV is typically nonzero.

On the mass anomaly of potential vorticity vortices

Quarterly Journal of the Royal Meteorological Society, 2015
The mass anomaly associated with piecewise constant symmetric potential vorticity (PV) vortices in rotating and stratified fluids is investigated. It is found that the absolute value of this mass anomaly depends linearly on the distance to the vortex centre and is therefore unbounded.

Vorticity, Potential Vorticity

1992
This lecture recalls the basic properties of vorticity and provides a summary of the main conservation laws associated with vorticity and its related quantities. It will be stated as clearly as possible how these different properties are used in industrial situations and in geophysical flows.
