Abstract
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 dee
