Experimental study of superharmonic internal wave resonant triads in finite-depth nonuniform stratifications

Year: 2024

Type: article

Abstract: Laboratory experiments are performed by setting up a finite depth nonuniform stratification profile with a pycnocline, and generating internal wave modes from one end of the tank using an internal wave generator. We present the first experimental evidence of superharmonic internal wave modes trapped in a pycnocline, which are excited by the resonant triad interaction of two internal wave modes at the same frequency.
