  abstract = {{T}he seasonal variability of the hydrology and the poleward subsurface {P}eru-{C}hile {U}ndercurrent ({PCUC}) off the central {C}hilean coast (29–41°{S}) were examined using a high-resolution regional model. {T}he model realistically reproduced observed sea level variability, such as intense anticyclonic eddies, the offshore intensification of the poleward flow and the reduced nearshore equatorward flow during autumn, as well as the equatorward intensification of nearshore meandering flow during spring. {V}alues for geostrophic eddy kinetic energy were high along the coast between 30° and 37°{S}, and lower south of this area. {T}he modelled poleward undercurrent showed latitudinal variability in velocity and transport. {T}he maximum average transport reported was 0.8 {S}v near 30°{S}, consistent with previous modelling studies and estimations derived from in situ observations. {T}he poleward reduction in undercurrent strength was shown to be partly generated by the poleward decrease in wind stress curl and by the formation of a westward jet near 35°{S} associated with westward-propagating eddies. {A} {L}agrangian analysis of the modelled water parcels transported by the undercurrent shows that only 14–20% of the subsurface floats transported by the undercurrent upwelled into the surface layer within the subsequent six months after their release. {T}he floats remaining within the subsurface layer were likely transported further south by the current, offshore by westward-propagating eddies or equatorward by the deeper part of the surface coastal current.},
