A general dispersion relation for internal gravity waves in the atmosphere or ocean, including baroclinicity, vorticity, and rate of strain

摘要

The dispersion relation for internal gravity waves in the atmosphere or ocean is generalized to include all components of baroclinicity, vorticity, and rate of strain. This generalization is expressed in a coordinate-free formulation suitable to be used as the Hamiltonian in a general ray tracing program. Comparison with other work in special cases is included.
