Nonlinear Interactions Between Oblique Wind Waves
Abstract
The nonlinear interaction between two oblique wind waves with the same wave speed is analyzed. The primary fluctuation, whose steepness is of the order of the cube of the density ratio of air to water, interacts with a secondary fluctuation of smaller steepness. The case where the secondary-wave frequency is higher than the primary frequency is studied. The nonlinear interaction generates N difference modes, where N is the smallest integer not less than the ratio of the secondary to primary frequencies. The amplitudes of the nonlinearly generated difference modes can grow faster than exponentially, and they can approach an exponential-of-an exponential growth stage.
