Internal waves in a compressible twolayer model atmosphere: Hamiltonian description
Abstract
We consider slow, compared to the speed of sound, motions of an ideal compressible fluid (gas) in a gravitational field in the presence of two isentropic layers with a small specificentropy difference between them. Assuming the flow to be potential in each of the layers (v_{1, 2} = ▿ϕ_{1, 2}) and neglecting the acoustic degrees of freedom (div(
