Abstract
Triadic resonance represents a mechanism by which internal wave energy is transferred to different frequencies and spatial scales. An experimental study of superharmonic internal wave excitation by temporal and spatial resonant interaction between internal wave modes is presented. The experimental observations are compared with theoretical amplitude evolution equations, following which, superharmonic generation near resonance is also studied.
