Internal gravity waves in the solar atmosphere. I  Adiabatic waves in the chromosphere
Abstract
The properties of adiabatic and linear internal gravity waves propagating in a solar wind model are discussed, using nonlinearity criteria unique to gravity waves to estimate wavebreaking heights. The results are used to deduce information on the possible role of gravity waves in the chromospheric energy balance. Maximum vertical velocity amplitudes for gravity waves are estimated to be on the order of 2 km/sec or less, and maximum horizontal velocity amplitudes are less than 6 km/sec, with temperature perturbations as large as 10002000 K. It is also estimated that gravity waves with an incident energy flux of one million ergs/sq cmsec can propagate upward to a maximum height of 9001000 km above the visible surface before nonlinearities lead to wave breaking, while those with an energy flux of 100,000 ergs/sq cmsec can reach maximum heights of 14001600 km.
