On the Evolution of Isolated, Nonlinear Vortices
Isolated Nonlinear Vortices axially symmetric vortex
2009/2/13
The evolution of an isolated, axially symmetric vortex is calculated with a quasi-geostrophic, adiabatic, hydrostatic. β-plane, two vertical mode model. The circumstances of greatest interest are thos...
The Scattering of Continental Shelf Waves by an Isolated Topographic Irregularity
Continental Shelf Waves Isolated Topographic Irregularity
2009/2/13
A model for the scattering of a continental shelf wave by a small, isolated and smooth topographic irregularity is developed. It is found that a wave of frequency ω, incident on a bump of a sufficient...
On the β-Induced Movement of Isolated Baroclinic Eddies
β-Induced Movement Isolated Baroclinic Eddies
2009/2/10
In this paper an analytical method is proposed for calculating the nonlinear β-induced translation of isolated baroclinic eddies. The study focuses on frictionless anticyclonic eddies with a uniform a...
The Interaction of a Two-Layer Isolated Mesoscale Eddy With Bottom Topography
Bottom Topography Eddy size mesoscale eddy
2009/2/6
The propagation of an isolated mesoscale eddy onto a western bounding topographic slope is examined through the use of a two-layer, primitive equation, numerical model. Variable parameters in the stud...
This paper examines the motion and propagation of an isolated of anomalous water on a beta-plane, considered previously by Nof (1981). His perturbation analysis is extended to show the following:

A shallow-water beta-channel model was used to carry out numerical experiments with cyclonic and anticyclonic disturbances of various strengths. The model is inviscid, so fluid elements conserve poten...
On the Interaction between Thin Isolated Eddies and Longshore Currents
Thin Isolated Eddies Interaction Longshore Currents
2009/1/19
A simplified two-layer analytical model describing the interaction between a longshore current and a thin lenslike eddy is considered. The eddy is situated near a vertical wall and is embedded in a fr...
The strength of storm generated coastal current and the intensity of coastal upwelling depend on the scales of the storm and the position of the storm with respect to the position or measurement. It i...
General integral relationships are derived for joint eddies in a three-layer ocean model as considered by Nof. The model is composed of two eddies in two superposed layers, the third layer being motio...
On the Propagation of Isolated Multilayer and Continuously Stratified Eddies
Isolated Multilayer Integra expressions Continuously Stratified Eddies
2009/1/12
Integra expressions are derived for the east-west velocity of propagation of isolated eddies on a beta plane. It is assumed that the eddies have no surface or floor expression, i.e., that both surface...
The interaction of two isolated lens-like eddies is examined with the aid of an inviscid nonlinear model. The barotropic layer in which the lenses are embedded is infinitely deep so that there is no i...
The Internal Barotropic Instability of Surface-Intensified Eddies. Part I：Generalized Theory of Isolated Eddies
Internal Barotropic Instability Surface-Intensified Eddies Isolated Eddies
2009/1/5
axisymmetric vortices which are purely barotropic, but are immersed in a stratified environment. The energy source is the kinetic energy of the barotropic vortex, which can be converted into baroclini...
On the Cylinder Collapse Problem, Mixing, and the Merger of Isolated Eddies
Cylinder Collapse Mixing Merger Isolated Eddies
2008/12/30
The Rossby adjustment of an initially circular column of water, the so-called collapse of a cylinder, continues to be a widely used method for forming lenslike eddies in the laboratory. Here, we consi...
Motion of Oscillatory Currents Past Isolated Topography
Oscillatory Currents Isolated Topography
2008/12/27
With the aim of developing increasingly realistic physical models of the interaction of ocean currents with isolated seamounts, laboratory experiments concerning the flow of an oscillatory current pas...

Rotating Modons Isolated Topographic Features
2008/12/23
In this paper steadily rotating modons that are trapped over topographic features with finite horizontal length scales are described. The quasigeostrophic equation over topography is transformed to a ...
