摘要：

Results obtained from the acoustic sounding of a fine layered wind-field structure in the stratosphere, mesosphere, and lower thermosphere with the use of infrasonic waves from surface explosions and volcanic eruptions are given. These results were obtained using a new method of acoustic sounding of the atmosphere based on the phenomenon of infrasound scattering from anisotropic wind-velocity and temperature inhomogeneities into the zone of acoustic shadow. This method makes it possible to obtain data on the vertical wind-velocity structure and its time variability at lower thermospheric heights that are less accessible to other remote methods of atmospheric sounding, including both meteor (up to a height of 105 km) and satellite measurements.
