Near-Inertial Waves and Turbulence Driven by the Growth of Swell

Abstract Between 5% and 25% of the total momentum transferred between atmosphere ocean is transmitted via growth long surface gravity waves called “swell.” In this paper, we use large-eddy simulations to show that swell-transmitted excites near-inertial drives turbulent mixing deepens a rotating, stratified, boundary layer. We find currents are less effective at producing turbulence layer than driven by an stress. Overall, however, differences swell-driven surface-stress-driven layers relatively minor. consequence, our results corroborate assumptions made in Earth system models neglect vertical structure fluxes instead parameterize all air–sea transfer processes with
