Large-scale perturbations near the solar atmosphere transition region

Peculiarities of acoustic-gravity wave near the solar atmosphere transition region are analysed. An investigation is based on an original characteristic relation of waves in a two layers model with a temperature jump. Special attention is paid to an analysis of the properties of the surface waves, generated by the source of mass, which crosses the solar atmosphere transition region. An exact analytical solution of this problem, which involves several modes propagating along the boundary, is found. It is shown on the basis of the obtained results that the wave front from the local instantaneous source moves in radial directions with acceleration. The obtained results are important for explanation of observed properties of wave perturbations near the solar atmosphere transition region, whose appearance correlates with coronas mass injection.
