“…The physical quantities in each cell are determined from the magnitude of the exchange of mass, momentum, and energy between neighboring cells. This method has been used by many authors, mainly in astrophysics (Sanders, 1976;Lea and De Young, 1977;Hirayama, 1978;Tanaka et al, 1979;Sanders and Tubbs, 1980;Bania and Lyon, 1980;Huntley, 1980Habe and Ikeuchi, 1980. These authors investigated gas flows, such as accretions onto galaxies, winds in clusters of galaxies and globular clusters, and the structure of the interstellar medium.…”

We have studied the behavior of nonlinear waves in isothermal atmospheres using an improved beam scheme method. It is shown that although the magnitude of the mass leakage due to side beams is significant, nevertheless in a motion close to hydrostatic equilibrium it can be suppressed, if special density distributions and/or suitable mesh intervals are selected. We adopt as the parameters for our model o$ the atmospheres M = 1 M,, R=50RO and T=4864K. The time variation of the physical quantities in each cell is found for several oscillation periods. The critical frequency for the model atmosphere in the case of waves with a weak nonlinearity seems to be consistent with that in the linear theory.
