Waves in the Solar Atmosphere. III. The Propagation of Periodic Wave Trains in a Gravitational Atmosphere
Abstract
The validity of weak shock theory for the propagation of waves in a gravitational atmosphere is examined by comparing its results with those from numerical integration of the exact equations of motion. The weak-shock approximation is not valid for periods longer than half the acoustic cutoff. In addition, the relation between the 300-s solar oscillation and chromospheric and coronal heating is described. Subject headings: atmospheres, solar - shock waves - solar atmospheric motions
