Abstract

The results of experimental studies of the propagation of a nonlinear acoustic wave (NAW) in the surface layer of the atmosphere are analyzed. The influence of the underlying surface and vegetation on the waveform, as well as on its amplitude and width of the frontal region, is considered. A large-scale effect of the interaction of a NAW with vegetation is revealed. It is shown that the expansion of the front region of the wave obeys the law of energy similarity. The necessity of searching for a mechanism that causes such a character of wave development is noted.
