Surface Roughness, Sea-Surface Slope and Wind-Wave Spectrum - Supplement.

Abstract

The measured mean square slope of the sea surface was shown to vary logarithmically with the wind velocity, and the rates of variation change with different boundary-layer regimes of the wind. Based on mean square slope data, the spectral constant of the directional wind-wave spectrum in the equilibrium range was considered to vary with wind regimes. The different rates of growth of slope with wind velocity is now interpreted as the result of the cutoff wave number extending into the capillary range at high wind velocities. (Author)
