The propagation of shock waves through a model atmosphere of an RR Lyrae type star is examined on the basis of Brinkley-Kirkwood method. The effects of gravity, radiation pressure and variation of specific heat ratio with depth are taken into consideration. It is supposed that a shock wave is generated below the convective region with the shock strength and shock energy taken as parameters. The numerical results show that the shock strength remains almost constant in the convective region while it abruptly increases from the top of this region toward the outer surface. The results are generally in good agreement with those of Sachdev and others. A brief discussion on the validity of our calculations of shock propagation is also presented.
