Comments on \"Estimates of kinetic energy dissipation under breaking waves\"

G Burgers

It is noted that the results of recent experiments on the enhancement of turbulent kinetic energy (TKE) dissipation below surface waves can be stated as follows. TKE dissipation is enhanced by a factor 15 H_{ws}/z at depths 0.5H_{ws} < z < 20 H_{ws} with respect to the wall-layer result = u_{*w}^3/(kappa z), where u_{*w} is the friction velocity in water and H_{ws} is the significant windsea wave height. For open ocean conditions, this reduces in most cases to an enhancement factor 10^6 u_{*w}^2/gz or u10^2/gz.
