Ecological Systems and Devices Annotation << Back Statistical analysis of the possible variations in the intensity of wind ripples due to internal waves in the presence of the films of surface-active substances Talipova T.G. Kurkina O.E. Giniyatullin A.R. Kurkin A.A. Pelinovsky E.N. Korol A.A. In this paper for the explain of the mechanism of formation of smooth strips (slicks) on the sea surface under the action of internal waves are used the film of surface-active substances, attendees everywhere in the sea. Experimental data on the real characteristics of marine films of surface-active substances are used for the calculation of histograms of contrast in the spectrum of wind ripples in the centimeter range for various parameters of the internal wave and wind wave lengths within the «ilm» mechanism of the effects of internal waves on the spectrum of wind-generated waves. It is shown that the ripple in the wavelength range 2…3 cm contrast weakly depends on the parameters of the internal waves (although with increasing internal wave amplitude), and the average number of 6…7 dB. For greater lengths ripple contrast is strongly dependent on the ratio of the rate of flow of water particles in the internal waves to the phase velocity of the internal wave. This dispersion deviations from average contrast values around the average value, which indicates a strong variation of contrast in each case. Nevertheless, it can be concluded relatively low sensitivity of «film» mechanism of action internal waves on the sea surface to a particular type of surface-active substances.
