Abstract

The possibilities of applying the philosophy of weakly turbulent Kolmogorov spectra to real wind waves are investigated. On the basis of theoretical estimates of the wave-wind interaction and experimental data, it is shown that the generation ranges in the kinetic equation for a wind wave spectrum which make the principal contribution to the integral values of the momentum, energy and action flows to waves from the atmosphere are localized in a region of fairly small scales. The dissipation related to wave breaking is concentrated in an even more fine-scaled region, and therefore in the case of fairly developed wave motion one may expect that the scales of the energy-containing vicinity of the spectral maximum and the scales of the generation and dissipation ranges are far apart.
