Evaluation of the linear theory satisfiability limits in propagation of the internal gravity waves

Abstract

A problem of finding the linear theory satisfaction limits in propagation of the internal gravity waves is considered. It is evident that internal gravity waves excitation, propagation in actual practice is highly nonlinear phenomenon. However with some reasonable assumptions it is possible to linearize equations of internal waves generation and propagation. It is shown that in interesting for us wavelength range we can use linear approximation during study of internal gravity waves dynamics. Similarly it is easy to evaluate also influence of other corrections to the linear theory of internal gravity waves generation and propagation, and the obtained results indicate adequacy and supportability of linear model wave dynamics.
