Rings, Eddies and Retroflection as a Mechanism for Inter-Basin Exchange

OCE 96-33655 Nof The project will apply an analytical approach to the investigation of eddy formation in the connecting regions between basins. The approach will allow nonlinear, periodic flows to be integrated over a control volume in a manner analogous to that used for steady flows. This greatly simplifies the problem so that important features of the eddies, such as their size and frequency of generation, can be determined without resolving the details of the generation process itself. The investigation will initially consider simplified analytical models, and later proceed to more realistic, two-layer, numerical modeling. Results are expected to complement ongoing observational and modeling studies of the Agulhas and Brazil current systems.
