    545 The OSMOSIS turbulent closure scheme is based on......   TBC 
     548Much of the time the turbulent motions in the ocean surface boundary 
     549layer (OSBL) are not given by 
     550classical shear turbulence. Instead they are in a regime dominated by an 
     551interaction between the currents and the Stokes drift of the surface waves known as 
     552`Langmuir turbulence' \citep[e.g.][]{mcwilliams.ea_JFM97}. 
     553The OSMOSIS model is fundamentally based on results of Large Eddy 
     554Simulations (LES) of Langmuir turbulence and aims to fully describe 
     555this Langmuir regime. 
     556 
     557The OSMOSIS turbulent closure scheme is a similarity-scale scheme in 
     558the same spirit as the K-profile 
     559parameterization (KPP) scheme of \citet{large.ea_RG97}. 
     560A specified shape of diffusivity, scaled by the (OSBL) depth 
     561$h_{\mathrm{BL}}$ and a turbulent velocity scale, is imposed throughout the  
     562boundary layer 
     563$-h_{\mathrm{BL}}<z<\eta$. 
     564However, rather than the OSBL 
     565depth being diagnosed in terms of a bulk Richardson number criterion, 
     566as in KPP, it is set by a prognostic equation that is informed by 
     567energy budget considerations reminiscent of the classical mixed layer 
     568models of \citet{kraus.turner_tellus67}.  
     569The model also includes an explicit parametrization of the structure 
     570of the pycnocline (the stratified region at the bottom of the OSBL). 
     571 
     572\subsubsection{The flux gradient model} 
     573 
     574The turbulent closure model 
     575also includes ``non-local'' (independent of the local property gradient) 
     576fluxes of tracers and momentum.
