Effects of wind-stress variability on nutrient transport into the mixed layer.

Résumé

This is a numerical study of the influence of unsteady dynamical atmospheric forcings on the physical entrainment of nutrient from deeper layers into the mixed layer. The one-dimensional model used is based on the Image and Image (1974, Journal of the Atmospheric Sciences, 31, 1791–1806) level 2 model which has been shown to be physically relevant. From the results, the time evolution of the physical entrainment of nutrient is not driven by the wind stress per se, but by the wind-surface current interaction. More importantly, it appears that the interaction between the time variability of the wind stress and the Coriolis period (which acts on the surface inertial currents and hence their phase direction with respect to the wind stress) can induce a pulsing character, at a time scale of some hours, of the nutrient flux through the thermocline. Because of the non-linear processes involved, the interaction has an effect not only on the instantaneous nutrient distribution, but also on the mean level of the nutrient transported.
