  abstract = {{S}imulating the oceanic circulation in {E}astern {B}oundary {U}pwelling {S}ystems ({EBUS}) is a challenging issue due to the paucity of wind stress products of a sufficiently high spatial resolution to simulate the observed upwelling dynamics. {I}n this study, we present the results of regional simulations of the {H}umboldt current system ({P}eru and {C}hile coasts) to assess the value of a statistical downscaling model of surface forcing. {T}win experiments that differ only from the momentum flux forcing are carried out over the 1992-2000 period that encompasses the major 1997/98 {E}l {N}ino/{L}a {N}ina event. {I}t is shown that the mean biases of the oceanic circulation can be drastically reduced simply substituting the mean wind field of {NCEP} reanalysis by a higher resolution mean product ({Q}uik{SCAT}). {T}he statistical downscaling model improves further the simulations allowing more realistic intraseasonal and interannual coastal undercurrent variability, which is notoriously strong off {C}entral {P}eru and {C}entral {C}hile. {D}espite some limitations, our results suggest that the statistical approach may be useful to regional oceanic studies of present and future climates.},
