Abstract:

The propagation of sound waves in the atmosphere is significantly effected by the nonuniformities of refractive index produced by turbulent fluctuations of temperature and windspeeds. Tur bulence causes fluctuations of amplitude and phase of sound waves, scattering, and additional attenuation. Author
