Abstract
An inviscid, incompressible, stably stratified fluid occupies a horizontal channel, along which an internal gravity‐wave packet is propagating. The wave induced mean motions are calculated, and the equations describing the evolution of the wave amplitude derived. When the group velocity of the wave packet coincides with a long‐wave speed there is a resonance, and the equations describing this resonance are derived.Keywords
