| Zusammenfassung |
| The transformation of Agulhas eddies near the continental slope of southern
Africa and their subsequent self-propagation are analyzed in both
observational data and numerical simulations. Self-propagation results from a
net dipole moment of a generalized heton structure consisting of a
surface-intensified anticyclonic eddy and deep cyclonic pattern. Such Agulhas
vortical structures can form near the retroflection region and further north
along the western coast of southern Africa. We analyze nonlinear topographic
wave generation, vortex deformations, and filament production as an important
part in water mass exchange. Self-propagating structures provide a conduit
for exchange between the deep ocean and shelf regions in the Benguela
upwelling system. |
