Abstract

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 Hws/z at depths 0.5 Hws < z < 20 Hws with respect to the wall-layer result ε= u*w3/κz, where u*w is the friction velocity in water and Hws is the significant wind-sea wave height. For open ocean conditions, this reduces in most cases to an enhancement factor 106 u*w2/gz ≈ U102/gz.
