Internal Waves Generated by a Vortex Pair

Abstract

Both observations and direct numerical simulations have shown that convecting storms create significant internal gravity wave activity. However, the physical mechanism for gravity wave generation is not clear. In this work, numerical simulations of a simple vortex model of convection have been performed for three different cases: a constant density case; a constant Brunt-Vasala frequency case: and a case with two layers, each with its own Brunt-Vasala frequency.
