  abstract = {{T}he influence of the eastern {P}acific equatorial circulation on the dynamics of the {N}orthern {H}umboldt {C}urrent {S}ystem is studied using an eddy-resolving regional circulation model forced by boundary conditions from three distinct ocean general circulation models. {T}he seasonal variability of the modeled nearshore circulation and the mesoscale activity are contrasted in order to evaluate the role of the density forcing. {T}he seasonal variability of the surface and subsurface alongshore currents strongly depends on the amplitude and timing of the seasonal eastward propagating equatorial waves. {T}he equatorward flow and upwelling intensity are also impacted by nonlinear processes, such as the seasonal generation of nearshore mesoscale eddies, which create alongshore pressure gradients modulating the surface current. {B}oundary conditions affect differently the intensity and phase of the eddy kinetic energy, as baroclinic instability is triggered by coastal waves during austral summer and fall, whereas it is sustained by the wind-driven upwelling during austral winter.},
