Abstract
A nonlinear model of the interaction between internal and Stokes surface waves is considered. An internal wave (IW) is set in the form of a large-scale variable surface flow, directed at a certain angle to the surface-wave (SW) field. Wave interaction patterns are studied, and a comparison with the results of linear modulation model is performed. The dependence of the refraction-wave pattern on the main parameters of the problem (SW steepness, strength and direction of IW-induced flow, and the angle between the SW and IW) is investigated.
