Résumé

The calculations of statistical characteristics of sound travel time fluctuations caused by atmospheric gravity waves (AWG) were presented. The strong nonlinear interactions between AGWs were shown to lead to the universal form for the high-wavenumber tail of the AGW spectrum. The vaiances, frequency spectra and structure functions were calculated using spectral forms. The calculations were used to interpret the experimental data on the statistics of acoustic pulse travel time fluctuations in stable atmospheric boundary layer (ABL).
