Distribution and Movement of Gulf Stream Rings David Y. Lai The distribution, number and movement of cyclonic Gulf Stream rings were estimated from an analysis of 50 000 temperature records ...
We have used linear quasigeostrophic dynamics to calculate the motion, decay and dispersion rates of radially symmetric initial disturbances with scales appropriate to Gulf Stream Rings. Baroclinic ri...
Data from the 1977 Cyclonic Ring Experiment is used to examine the, density, velocity, vorticity and energy distributions in a Gulf Stream cyclonic ring. A time series on ring BOB provides information...
Eight cruises over a 10-month period in the North Atlantic have provided the Cyclonic Ring Experiment with observations of two rings. Life histories, structure and structural changes have been studied...
Numerical simulations of the propagation of cyclonic Gulf Stream rings are made using a primitive equation β-plane model of a flat-bottomed two-layer ocean with a rigid lid. Initially circular eddies ...
Asymmetric instability of a circular Gaussian ring and evolution of a ring shape in a nonlinear case are studied using a two-layer quasi-geostrophic model on an f plane. Ring behavior is classified on...
Using the historical data set, this study describes the anticyclonic rings that separated from the Loop Current in the eastern Gulf of Mexico. Six quasi-synoptic data sets are used to describe the evo...
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 ...
Observations suggest that heat loss to the atmosphere causes an important modification of the density structure of warm core rings. In this study, f-plane models of rings under a cooling atmosphere ar...
Some simple air-sea momentum transfer models, which include sea surface velocity and temperature, are considered for their effects on Gulf Stream rings. Perturbing the stress calculation with sea surf...
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...
The theory of the evolution of rings under a Cooling atmosphere is extended in two ways. First effects of stratification are studied analytically through the use of a “two and one-half” layer model. S...
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...
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...
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...
