 r11674 Much of the time the turbulent motions in the ocean surface boundary layer (OSBL) are not given by classical shear turbulence. 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}. classical shear turbulence. Instead they are in a regime known as Langmuir turbulence',  dominated by an interaction between the currents and the Stokes drift of the surface waves \citep[e.g.][]{mcwilliams.ea_JFM97}. This regime is characterised by strong vertical turbulent motion, and appears when the surface Stokes drift $u_{s0}$ is much greater than the friction velocity $u_{\ast}$. More specifically Langmuir turbulence is thought to be crucial where the turbulent Langmuir number $\mathrm{La}_{t}=(u_{\ast}/u_{s0}) > 0.4$. The OSMOSIS model is fundamentally based on results of Large Eddy Simulations (LES) of Langmuir turbulence and aims to fully describe $h_{\mathrm{BL}}$ and a turbulent velocity scale, is imposed throughout the boundary layer \$-h_{\mathrm{BL}}
