Features of Modeling the Wave Dynamics of Stratified Media Taking into Account Viscosity and Compressibility

Abstract

In this work the peculiarities of modeling the wave dynamics of stratified media are considered taking into account compressibility and viscosity. It is shown that the boundary layers may have a thickness of up to several meters under real ocean conditions, which is several percent of the half-wavelength of internal gravity waves for lower modes, and, because the several lower modes are excited in the ocean, viscosity has no significant impact on the wave dynamics of natural stratified media, ocean and atmosphere. The main features of dispersion relationships describing the wave dynamics of acoustic-gravity wave pulses in stratified media are investigated taking into account their compressibility.
