Oceanic and atmospheric dynamics are often interpreted through potential vorticity, as this quantity is conserved along the geostrophic flow. However, in addition to potential vorticity, surface buoyancy is a conserved quantity, and this also affects the

The structure of three-dimensional quasi-geostrophic (3D QG) turbulence is quantitatively different from two-dimensional (2D) barotropic turbulence. This is shown by separating the potential vorticity fields into three components: vortex cores; the circulation cells surrounding the cores; and the back...

A diagnosis of error evolution in the National Center for Atmospheric Research quasigeostrophic (QG) model is performed using potential vorticity (PV) inversion and localized Eliassen-Palm flux diagnostics following the ideal cyclone development under the perfect model assumption. The error evolution is ...

Quasi-geostrophic (QG) analysis of the atmosphere utilizes predefined isobaric surfaces to ascertain vertical motion. One equation of the QG system is the omega equation that states that vertical forcing results from differential vorticity advection and thickness advection. Two problems arise when using ...
