ABSTRACT

Del Genio et al. 1978

Del Genio, A.D., J.M. Straus, and G. Schubert, 1978: Effects of wave-induced diffusion on thermospheric acoustic-gravity waves. Geophys. Res. Lett., 5, 265-267.

When wave-induced diffusion is included in the equations governing acoustic-gravity wave propagation in an atmosphere in diffusive equilibrium, it is found that phase and amplitude relationships between the density fluctuations of individual atmospheric constituents agree with AE-C satellite observations of wavelike structure only over a narrow range of wave periods. For a 400-km horizotal wavelength, the observations are consistent with internal gravity waves of periods 11.5-22 minutes propagating at phase speeds 300-600 m/sec.
