    249248Following \citet{Mellor_Blumberg_JPO04}, the TKE turbulence closure model has been modified  
    250249to include the effect of surface wave breaking energetics. This results in a reduction of summertime

    334333% from Burchard et al OM 2008 :  
    335 % the most critical process not reproduced by statistical turbulence models is the activity of internal waves and their interaction with turbulence. After the Reynolds decomposition, internal waves are in principle included in the RANS equations, but later partially excluded by the hydrostatic assumption and the model resolution. Thus far, the representation of internal wave mixing in ocean models has been relatively crude (e.g. Mellor, 1989; Largeetal., 1994; Meier, 2001; Axell, 2002; St. Laurent and Garrett, 2002).
