Short summary
We evaluated the seasonal variability in Ekman transport, pumping and their relative contribution to total upwelling along the central-northern Chile region (~30ºS) from a high-resolution atmospheric model simulation. The results showed that the relative contribution of Ekman transport and pumping to the vertical transport along the coast, considering the estimated wind drop-off length, indicated meridional alternation between both mechanisms, modulated by orography and the intricate coastline.
We evaluated the seasonal variability in Ekman transport, pumping and their relative...
