  abstract = {{T}he influence of chlorophyll shading on ocean dynamics has been usually disregarded in eastern boundary upwelling systems modeling studies in spite of their very high primary productivity. {H}ere, we study how this effect impacts on the {P}eru upwelling system using a regional mesoscale-resolving physical biogeochemical coupled model. {W}e show that the shading effect leads to a surface cooling of up to 1 degrees {C} on the shelf due to subsurface cooling of the source waters during their transit toward the shelf. {T}he shading effect leads to a more realistic subsurface stratification, a slowdown of the alongshore currents, and a shoaling of the oxycline. {I}mpacts on the regional model biases show that the shading effect needs to be taken into account in both physical and coupled physical-biogeochemical regional models of upwelling systems.},
