Abstract:

The mean square slope of the sea surface is shown to vary logarithmically with the wind velocity, and the rate of variation changes with different boundary-layer regimes of the wind. Based on mean square slope data, the spectra constant of the directional wind-wave spectrum in the equilibrium range is seen to vary with wind regimes. An approximate correlation is presented between the mean square slope and the roughness height of the sea surface. Author
