Representation of eddies in climate models by a potential vorticity flux
… This force manifests itself as a flux of potential vorticity (PV) - a quantity that incorporates both eddy momentum and heat transporting properties. Moreover, the dynamic velocities are those of the residual mean circulation, a much more relevant velocity for understanding heat and tracer …

Observations of oceanic potential vorticity and its relationship with other tracers
… (SST) has been suggested as a proxy for potential vorticity (PV), which may then be inverted to give velocity. However, little is known about the relationships between PV and other water mass tracers, as these have not previously been thoroughly examined. In this thesis, the …

Horizontal and vertical structure of velocity, potential vorticity and energy in the Gulf Stream
… Stream, from which a cross-section of the mean potential vorticity can be produced. The latter shares many common feature with cross-sections from past work for a nearby site, as well as analogous data from a three-layer numerical model, thus suggesting that they are robust features of Gulf …

An analytic examination of the effect of the stratosphere on surface climate through the method of piecewise potential vorticity inversion
… surface of the earth. The method of piecewise potential vorticity inversion was employed in the diagnosis of the magnitude of and dynamics behind the stratosphere-surface link in both the transient and stationary cases. The potential vorticity inversion results in both the transient and …

Inhomogeneous potential vorticity homogenization and equilibrium in simple models of baroclinic instability with implications for the extratropical circulation by Pablo Zurita-Gotor.
… propose basic states with homogenized potential vorticity. In this thesis we investigate the degree of potential vorticity homogenization in the extratropical troposphere. We show that homogenization is only observed across a shallow region around 700 mb, and propose an adjusted state …

Rotating gravity current and channel flows
… theory is the inclusion of an upstream potential vorticity boundary conditionin the current. The approach taken is based on a method used by van Heijst (1985). The governing equations and preliminary solutions for each case are derived. The potential vorticity theory provides an insight …

The structure and transport of the Brazil Current between 27⁰ and 26⁰ South
… model performs remarkably well. Finally, total potential vorticity is calculated from the hydrographic sections. Contrary to what one might expect, the reference level choice is not a significant problem: where currents are large, most of the signal in relative potential vorticity comes from the …

An experimental study of the spread of buoyant water into a rotating environment
… We focus in particular on the role that finite potential vorticity and background turbulence play in determining the flow properties. When water of an anomalous density enters into an oceanic basin, gravity-driven surface flows can be established as a result of the density difference. These …

Eddy forcing of the mean circulation in the western North Atlantic
… of the eddy and mean terms in the mean momentum, vorticity, and heat balances in three regions of the Western North Atlantic -- the northern recirculation, the southern recirculation, and the mid-ocean. The data from the last decade of field experiments suggest somewhat different conclusions from …

The structure of the Kuroshio west of Kyushu

Analysis of the potential vorticity based on the January 1986 absolute geostrophic velocity field shows that the total potential vorticity in the Kuroshio may be approximately given by the product of the vertical gradient of the potential density and the sum of the …

The vertical structure of the wind-driven circulation
… the Batchelor-Prandtl theorem suggests that the potential vorticity is uniform inside these laterally isolated regions. The requirement that the potential vorticity be uniform leads simply and directly to predictions of the shape and extent of the wind gyre and the vertical structure of the …
