Dynamics of the antarctic upper atmosphere
Planetary and Space Science, 1989Abstract This review is limited to consideration of ground-based radio and optical measurements on winds in the Antarctic mesosphere and thermosphere. Observations on the mean flow and the 12 and 24 h tides in the 70–110 km range are discussed in relation to models.

Dynamics of the upper atmosphere
Journal of Geophysical Research, 1959The mean temperature and motional structure of the stratosphere, mesosphere, and lower ionosphere are described, and the thermodynamics of these regions is considered briefly. Possible disturbances on the mean motion are discussed. It is concluded that vertical convection is a very unlikely cause of such disturbances, that slantwise convection ...

Ion Dynamics and Velocities in Titan's Upper Atmosphere
2023The Cassini mission yielded a treasure trove of information on Saturn's largest moon Titan. With many flybys of this complex moon Cassini revealed many aspects of Titan's upper atmosphere and interaction with Saturn's magnetosphere. In many ways Cassini revealed that this moon is unique in that it sustains a dense atmosphere and ionosphere even without

A dynamical model of upper-atmospheric helium
Journal of Geophysical Research, 1977This numerical study of the global distribution of helium in the terrestrial thermosphere is based on the extension of a three-dimensional single-fluid numerical model of the thermosphere previously developed by the authors to treat the dynamics of a minor gas imbedded in a background gas made up of N2, O2, and O.

Magnetospheric convection and upper atmospheric dynamics
Journal of Geophysical Research, 1976Ionospheric plasma, driven into motion by the magnetospheric convection electric field, interacts with the neutral upper atmosphere via collisions. These collisions provide both a momentum source (ion drag) and an energy source (Joule heating) for the neutral atmosphere.

Archives for Meteorology, Geophysics, and Bioclimatology Series A, 1983
A time-dependent, primitive-equation numerical model is used to test the hypothesis that solar variations induce changes in the distributions of basic state variables at high levels in the atmosphere, and thus induce changes in planetary-scale wave structure at lower atmospheric levels.
