Abstract

The purpose of this study is to investigate the means by which energy is transferred among internal gravity waves. The transfer of energy in weakly interacting flows is characterized by resonant interactions in which the interaction time scale is much greater than the component wave periods. The energy transfers occurring in a more nonlinear system, where interaction time scales can be of the same order of the wave period, were practically untreated. In the present study, we will discuss the dynamics of waves in such a nonlinear regime.
