Acoustic-gravity waves in atmospheric and oceanic waveguides
The Journal of the Acoustical Society of America, 2012A theory of guided propagation of sound in layered, moving fluids is extended to include acoustic-gravity waves (AGWs) in waveguides with piecewise continuous parameters. The orthogonality of AGW normal modes is established in moving and motionless media.

Internal atmospheric gravity waves at ionospheric heights
Canadian Journal of Physics, 1960Irregularities and irregular motions in the upper atmosphere have been detected and studied by a variety of techniques during recent years, but their proper interpretation has yet to be established. It is shown here that many or most of the observational data may be interpreted on the basis of a single physical mechanism, namely, internal atmospheric ...

Atmospheric Gravity Waves and Coastal Cyclones
Monthly Weather Review, 1979Abstract Relations between the behavior of atmospheric gravity waves and the meteorological conditions during the approach of coastal cyclones at Palisades, New York (near New York City) are investigated. It is shown that the temperature and wind conditions favoring the development of the largest amplitude waves are most likely to occur when coastal ...

Thermospheric heating by atmospheric gravity waves
Journal of Atmospheric and Terrestrial Physics, 1973Abstract This paper investigates the irreversible heat input generated by atmospheric gravity waves at thermospheric heights and the corresponding temperature increase of the neutral gas. A numerical example yields height profiles of the heat input and temperature increase which are similar to the height profiles of the solar EUV heat source and ...

Acoustic-gravity waves in a nonadiabatic atmosphere
Izvestiya, Atmospheric and Oceanic Physics, 2007The effect of a real departure of the atmosphere from the adiabaticity condition on the generation and dissipation of acoustic-gravity waves (AGWs) throughout the entire height of the atmosphere up to the mesopause (≈90 km) is studied. The results of solving the derived dispersion equation can be helpful in the formation of boundary conditions during ...

Nonlinear saturation of atmospheric gravity waves
Journal of Atmospheric and Terrestrial Physics, 1994Abstract The governing equation for atmospheric gravity waves is deduced; it contains nonlinear terms of up to third-order perturbations. This general equation is used to derive the nonlinear equation for the amplitude of the velocity perturbation in a quasi-monochromatic wave, taking into account the secular terms.

Observations of Gravity Waves in the Solar Atmosphere
1986In direct analogy to the techniques of seismic measurements on the Earth, information on the vertical structure of the solar atmosphere can be obtained by monitoring the differences of arrival times of periodic signals at various “stations” (= successive line forming layers) or the time lag between signals of different type arriving at the same ...
