Abstract
The effect of a nonuniform altitude temperature distribution in the atmosphere on acoustic gravity waves (AGWs) propagating in the atmosphere is studied. The reflection and transmission coefficients of waves are found for layers with linear and parabolic vertical temperature profiles. The conditions for waveguide propagation of AGWs in such layers are discussed. Examples of altitude temperature profiles obtained in experiments on the scattering of radio waves on artificial periodic plasma inhomogeneities in the lower thermosphere are given.
