Formulation of Initial-Boundary Conditions at Numerical Modeling of Wave Dynamics of Stratified Media

In this work the initial-boundary conditions for numerical modeling of wave dynamics of stratified media are formulated. Two concrete examples are considered that illustrate this approach to calculation of gravity wave packages far away from sources, perturbations given on some boundary of a layer of stratified medium. The proposed initial-boundary conditions given on the moving plane can be determined both experimentally and as a result of accurate numerical calculations. In the analytically obtained initial-boundary conditions, many real-world information can be imposed on the basis of which the linear theory of propagation of internal gravity waves far away from the nonlinearity regions can yield physically adequate results.
