  abstract = {{C}oupled ocean-atmosphere simulations are carried out for the {M}ozambique {C}hannel, the {A}gulhas {C}urrent system, and the {B}enguela upwelling system to assess the ocean surface current feedback to the atmosphere and its impact on the {A}gulhas {C}urrent ({AC}) retroflection and leakage. {C}onsistent with previous studies, the authors show that the current feedback slows down the oceanic mean circulation and acts as an oceanic eddy killer by modulating the energy transfer between the atmosphere and the ocean, reducing by 25% the mesoscale energy and inducing a pathway of energy transfer from the ocean to the atmosphere. {T}he current feedback, by dampening the eddy kinetic energy ({EKE}), shifts westward the distribution of the {AC} retroflection location, reducing the presence of eastern retroflections in the simulations and improving the realism of the {AC} simulation. {B}y modulating the {EKE}, the {AC} retroflection and the {G}ood {H}ope jet intensity, the current feedback allows a larger {AC} leakage (by 21%), altering the water masses of the {B}enguela system. {A}dditionally, the eddy shedding is shifted northward and the {A}gulhas rings propagate less far north in the {A}tlantic. {T}he current-wind coupling coefficient s(w) is not spatially constant: a deeper marine boundary layer induces a weaker s(w). {F}inally the results indicate that the submesoscale currents may also be weakened by the current feedback.},
