摘要：
We present the results of measuring characteristics of the ionosphere and neutral atmosphere by the method of resonant scattering of radio waves by artificial periodic irregularities of the ionospheric plasma in the altitude range 90-120 km. It is shown that the altitude-time variations of the measured characteristics are in many respects stipulated by the propagation of atmospheric waves. Hydrodynamic instabilities in the mesosphere-lower thermosphere are analyzed. Criteria of development of different-type instabilities are presented. Contribution of different processes to the dynamics of the medium is estimated on the basis of the measurement results.
