Abstract:
The characteristics of magnetohydrodynamic fast wave propagation in the solar stratified atmosphere are studied here. Partly ionization considered beside the stratified solar atmosphere consisting chromosphere, transition region and corona in the form of a two-fluid MHD function. Different magnetic field were used in the simulation. Then the wave propagation in the solar stratified atmosphere are studied by the ray tracing method. The result may explain the characteristic in observations of Moreton and EUV waves. The speeds and propagated characteristics in chromosphere and corona of the wavefronts are in agreement with those observed in Moreton and EIT waves, respectively.
