Abstract

The modulation of the spectral density of wind-waves 4 mm to 12 cm long by sinusoidal surface currents is measured using a scanning slope sensor. The results indicate that the magnitude of modulation decreases as wind speed or wavenumber increases, in qualitative agreement with the prediction of the relaxation mechanism. Quantitatively, the linear relaxation theory was found to under-predict the magnitude of modulation.
