The equilibrium range cascades of wind-generated waves
Abstract
It was established theoretically by Zakharov and Filonenko (1966) that the direct cascade region of the equilibrium range of the spectrum should follow an f -4 variation. This has since been verified from experimental data, by Toba (1973), Donclan et al (1985) and others. In this study we present a numerical verification of this f -4 variation, assuming physically realistic parameterizations for nonlinear wave-wave interactions, S nl, for energy input to waves by the wind, S in and removed by wave - breaking dissipation, S ds.
