Anomalous Heating of the Solar Atmosphere in the Epoch of the Solar Activity Minimum

Abstract

The article studies the physical mechanism of the generation of a steady stream of weak shock waves at the photospheric level during the epoch of the solar-activity cycle minimum. The distribution of altitude thermodynamic parameters within the solar chromosphere are calculated with the relaxation method. A nonlinear increase in wave-flow power in the lower layers of the solar atmosphere has been determined in the epoch of increased cycle activity. The physical mechanism of radiative heating of the solar atmosphere is studied at the stage of increased cycle activity.
