  abstract = {{A} regional eddy-resolving oceanic model spanning the 1992-2000 period is used to study the influence of 50 to 80 day intraseasonal equatorial {K}elvin waves ({IEKW}) on mesoscale eddy activity off the west coast of {P}eru and northern and central {C}hile. {T}he model is shown to realistically simulate nearshore intraseasonal sea level variability, poleward propagation of equatorially forced coastal trapped waves along the coastal waveguide, and offshore variability related to mesoscale eddies and {R}ossby waves ({RW}). {I}n agreement with linear theory, {RW} are confined equatorward of similar to 12 degrees {S} in the 50-80 days period range. {S}outh of that critical latitude, westward propagation is dominated by energetic mesoscale signals resulting mainly from coastal flow instability. {S}ensitivity experiments to the open boundary conditions are then used to estimate to what extent eddy activity is impacted by the remote equatorial forcing. {A} coastal increase in eddy kinetic energy related to the energetic 60 day {IEKW} activity present in the open boundary forcing is evidenced and is largest off northern {P}eru, whereas no major changes are observed offshore. {A}dditional regional simulations with different open boundary conditions corroborate our findings and suggest that this limited effect of {IEKW} on the offshore eddy kinetic energy may be a robust feature.},
