Abstract: The authors investigate the influence of steep bottom topography on the propagation of a vortex in a two-layer quasigeostrophic model. The vortex is intensified in the upper layer and the planetary beta effect is taken ...

Abstract: The beta effect on the evolution of intrathermocline vortices, such as anticyclonic Mediterranean Water eddies (meddies), is investigated in a quasigeostrophic numerical model with fine high vertical resolution. The authors ...

Abstract: This paper considers several influences of mixing on the stability of oceanic boundary currents, analyzed primarily in terms of the effects of mixing on the distribution of potential vorticity. This perspective relates ...

Abstract: This paper revisits the thermal mass inertia correction of Sea-Bird Electronics, Inc., (SBE4) conductivity probes for the calculation of salinity. In particular, it is shown that the standard parameters recommended for the ...

Abstract: The nonlinear interaction of a localized vortex with a vertically sheared mean flow has been studied using numerical and asymptotic methods in a multilayer quasigeostrophic model on the beta plane. Numerical solutions ...

Abstract: This paper examines the stability properties of coastal currents having the same potential vorticity (PV) structure but different transports and widths. The PV structure is chosen so as to verify the Charney?Stern necessary ...

Abstract: The authors study the splitting of a coherent vortex by a large-scale baroclinic background current. A criterion for the splitting of the vortex is defined, and the process is then studied numerically and analytically in ...

Abstract: Numerical experiments are carried out on the f plane, using a shallow-water isopycnal model, to analyze the behavior of a surface-intensified anticyclonic vortex when it encounters an isolated seamount. The advection by ...

Abstract: The possibility for a preexisting surface-intensified anticyclone to subduct beneath a surface front is investigated using an isopycnal numerical model. Subduction occurs for strong coherent vortices and is usually accompanied ...
