  abstract = {{W}e analyze the results of a regional model of the {S}outhern {B}enguela upwelling system forced by wind stress fields derived from {Q}uik{SCAT} observations. {T}wo different horizontal resolutions are considered for the wind stress: {QS}25 and {QS}50, corresponding to native 25 and 50 km grids, respectively. {T}he differences between both products highlight the primary importance of fine-scale momentum fluxes for both the structure and intensity of the wind- and wind-curl-driven upwelling. {U}sing {QS}25, we show that the coastal {E}kman transport is reduced, leading to a warmer {SST} and a reduced oceanic coastal jet. {QS}25 finer wind stress curl patterns also favor the development of a stronger and shallower poleward undercurrent. {T}he addition of a coastal wind correction to {QS}25 lets us investigate the possible implications of an imbalance between {E}kman transport and {E}kman pumping: a wind reduction in the coastal band often reduces the {SST} cooling, but the two mechanisms compensate each other when the characteristic length scales of the coastal upwelling and the orography-induced wind drop-off are similar.},
