Study of Acoustic-Gravity Wave Spectra in the Atmosphere Using Mesosphere-Stratosphere- Troposphere Radar (Propagation, Universal Spectrum)
Current research indicates that acoustic-gravity waves can greatly influence the large-scale dynamics of the middle atmosphere. The morphology and structure of the atmospheric processes which cause this phenomenon can be better understood by the study of acoustic-gravity wave spectra. In order to …

Gravity Wave/large-Scale Flow Interactions: A Comparison of Model Predication and Observation
… signatures predicted by three commonly used gravity-wave parameterizations: critical level filtering, linear saturation filtering, and diffusive filtering. A one-dimensional, time-independent model filters various gravity-wave spectra using the criteria for each of these parameterizations. …

Theory and Observations of Horizontal and Vertical Structure of Gravity Wave Perturbations in the Middle Atmosphere
Gravity wave models for the horizontal wave number spectra of atmospheric velocity and density fluctuations are derived by assuming that both saturated and unsaturated waves obey the polarization and dispersion relations and that the joint $(m{,}\omega)$ spectrum is separable. The models show that …
