Abstract

A problem of acoustic radiation propagation through a 500-m layer of the plane-stratified turbulent atmosphere is solved by the Monte Carlo method. Quantitative estimates of variations of the multiple scattering contribution to the transmitted radiation intensity are presented. Calculations were performed for mid-latitude regional models of the atmosphere in winter and summer in clear and cloudy days for a point-sized omnidirectional source placed at altitudes Hs = 5–35 m above the Earth’s surface. Results of calculations for sound frequencies in range F = 500–4000 Hz with a step of 500 Hz and for outer scale of turbulence L0 = 1–5 m with a step of 1 m and 10–100 m with a step of 10 m demonstrate significant regional and seasonal variability of the multiple scattering contribution.
