LOCALIZED AND VOLUME INTERNAL WAVES IN A STRATIFIED FLUID CONTIGUOUS TO A MIXED-LAYER

Dispersion relations, the rate of energy transfer, orthogonality and c ompleteness relations and, also, the functions describing the vertical structure of two types of internal waves (perturbations localized clo se to the boundary and volume perturbations), which exist in an expone ntially stratified medium contiguous to a homogeneous layer of finite thickness without any discontinuity in the density are calculated with out recourse to the Boussinesq approximation.
