Mathematical Model of Wave Perturbations in the Solar Atmosphere near Resonance Frequencies
Analytically and numerically calculations according to the original effective algorithms for largescale
acoustic-gravity wave perturbations in the chromosphere from sources at the level of the photosphere are
analyzed. Limitations to the energy flux of acoustic-gravity waves from the photosphere through the
chromosphere are formulated. Structure of a narrow region with elevated pressure at the resonance altitude
where the horizontal phase wave velocity is equal to the sound velocity is examined.
