Instead they are in a regime dominated by an interaction between the currents and the Stokes drift of the surface waves known as `Langmuir turbulence' \citep[e.g.][]{mcwilliams.ea_JFM97}. The OSMOSIS model is fundamentally based on results of Large Eddy Simulations (LES) of Langmuir turbulence and aims to fully describe this Langmuir regime. The OSMOSIS turbulent closure scheme is a similarity-scale scheme in the same spirit as the K-profile parameterization (KPP) scheme of \citet{large.ea_RG97}. A specified shape of diffusivity, scaled by the (OSBL) depth $h_{\mathrm{BL}}$ and a turbulent velocity scale, is imposed throughout the boundary layer \$-h_{\mathrm{BL}}
