Abstract
Paper presented to the 3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015.
Taking into account the most recent net radiation function model and five different kinds of heating scenarios for the upper solar atmosphere, we have defined some regions where the magnetoacoustical amplification may take place. The nonlinear equation describing the evolution of fast and slow magnetoacoustic waves in a heat-releasing completely ionized plasma has been obtained. The shape and parameters of the magnetoacoustic pulse that is an automodel solution of this equation under conditions of magnetoacoustic instability have been determined
