An expression for the change in the amplitude of waves in a moving medium was obtained, according to which in an oncoming inhomogeneous wind, the amplitude of the waves increases approximately according to a linear law, which is consistent with the data of satellite observations. It is shown that the rotation of the atmosphere leads to a modification of the continuous spectrum of evanescent AGW. A method for recognizing acoustic-gravitaty waves in the atmosphere based on satellite measurement data has been developed, which allows identification of different types of atmospheric waves in experimental data. A procedure for wavelet estimation of the entropy of the normalized median absolute deviation has been developed. Implementation of the procedure in the MATLAB system was applied to the processing of satellite data. Advantages over the well-known procedure of wavelet estimation of dispersion entropy were revealed. Measures have been taken to ensure the scientific, organizational and methodical support of the Program. Product Description popup.authors Voitsekhovskaia Anna Dmitrievna Zhul Ihor T.
