Abstract
The specific features in the propagation of acoustic waves with a finite amplitude in the model of an isothermally viscous stratified atmosphere have been studied based on the analytical solutions. The Khokhlov—Zabolotskaya and Burgers equations have been generalized for a stratified atmosphere. The selfsimilar solution for a generalized Burgers equation with variable viscosity has been found. The asymptotic solution for an initial sinusoidal disturbance has been obtained. The solutions can be used to seismically analyze induced acoustic fields in a wide frequency band.
