Spatial-Temporal Structure of Fluctuations of the Amplitude and Phase of Acoustical Wave Propagating Through the Atmospheric Boundary Layer

Abstract

An effect of the atmospheric channel on near-ground propagation of acoustic waves considered. The structure of the amplitude and phase fluctuations of acoustic waves propagating through the turbulent atmosphere near the ground has been analyzed. The structure of the temperature and wind velocity field and vertical profiles of the outer scale of atmospheric turbulence have been experimentally investigated.
