Measurements of the fine space-time structure of short gravity-capillary waves in the presence of turbulence, as well as Ku-band scattering at grazing and moderate incidence from mechanically-generated waves in a wave channel are presented. This study was stimulated by the need to investigate the influence of nonlinear features of the scattering surface, which contribute to scattering at grazin...

A-interrupted alpha: the normal waking 10.per-second rhythm dominates the pattern B-Zozu voltage: the alpha rhythm is lost C-spindles: short groups (“spindles”) of 14-per-second waves appear and also random “delta” * waves 0.2 second or more in length D-spindles plus random: both types of wave increase in voltage and the delta waves become longer E-random: the 14.per-second waves become inconsp...

Recent field observations and modelling of breaking surface gravity waves suggest that air-entraining breaking is not sufficiently dissipative of surface gravity waves to balance the dynamics of wind-wave growth and nonlinear interactions with dissipation for the shorter gravity waves of O(10) cm wavelength. Theories of parasitic capillary waves that form at the crest and forward face of shorte...

This paper is concerned with the real-time observation system of optical devices for recording of sea waves characteristics in wide range of wavelength from centimeters to hundreds meter. The energy spectra of short waves are obtained in real time by spectral analysis of sea surface image [1] with spectral analyzer operating under no coherent light. The spectral-kinematics characteristics of lo...
