Linear Stability of Large, Elliptical Warm-Core Rings
Linear Stability Elliptical Warm-Core Rings
2009/1/12
An analytical solution for a confined, elliptical lens of light water is perturbed to test the linear stability of elongated warm-core rings. The asymptotic expression of the solution when the eddy's ...
Intense cooling of a warm-core ring or warming of the fluids surrounding a ring can increase the density of that ring relative to the surrounding fluids. This increase in density can cause the ring to...
Translational Velocity of Warm Core Rings Relative to the Slope Water
Translational Velocity Warm Core Rings Slope Water
2009/1/4
Five warm Core rings were examined during short time intervals using thermal infrared satellite imagery. A total of 12 pairs of observations of these rings were made, all east of 72°W. The observation...
Interactions of Cold- and Warm-Core Rings with Environmental Shear
Environmental Shear Cold Warm-Core Rings
2009/1/4
A two-layer analytical model of cold- and warm-core rings has been constructed to explore steady interactions of isolated eddies with horizontally sheared flows around and below the eddies. Steady inv...
Separation of Warm-Core Rings in the Gulf of Mexico
Warm-Core Rings Mexico anticyclonic rings
2008/12/17
The separation of anticyclonic rings is studied using a 12-level primitive equation numerical model of the western North Atlantic. The “Gulf Stream Formation Region” model is based on the Bryan-Cox-Se...
A Numerical Simulation of the Evolution and Propagation of Gulf Stream Warm Core Rings
Numerical Simulation Evolution Propagation Gulf Stream Warm Core Rings
2008/12/15
The evolution and propagation of Gulf Stream warm core rings in a flat-bottom, β-plane ocean are studied using a three-dimensional primitive equation model. Rings are produced by a heat source that is...
Elliptical Warm-Core Rings in a Two-Layer Ocean with Ambient Shear
Warm-Core Rings Ambient Shear Two-Layer Ocean
2008/12/12
The rodon solution for an elliptical vortex with outcropping interface is extended from the reduced-gravity limit to the two-layer model. Motions in the lower layer consist of a reaction to the presen...
Geostrophic Vortex Merger and Streamer Development in the Ocean with Special Reference to the Merger of Kuroshio Warm Core Rings
quasigeostrophic shallow-water Kuroshio Warm Core Rings Geostrophic Vortex Merger
2008/12/11
A simple, quasigeostrophic, two-layer model was used to study the interactions of two like-signed vortices and streamer development in the ocean. In particular, models corresponding to the observed me...
