Resonant forcing of nonlinear internal waves by a density current released into a two-layer fluid

ORAL

Abstract

The propagation of a density current released by a dam break into a fluid with two-layer stratification is a geophysical fluid dynamics problem relevant to the ocean and atmosphere. Analogous to topographic forcing, a transcritical resonance is observed when the speed of the density current falls within a range, $c_l
