This process is affected by ion drag in that any decrease in the electron density at the equator would increase the wind velocity. This in turn would enhance the diffusion process, which, if dominant, would explain.

Neutral gas constituents.

It is convenient to separate the atmospheric regions according to the two temperature minima at about 12 km altitude (the tropopause) and at about 85 km (the mesopause) (Figure 1).The thermosphere (or the upper atmosphere) is the height region above 85 km, while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and.

The input parameters are: the structural parameters of empirical thermospheric models (temperature, composition), electric fields, solar UV-radiation spectrum, corpuscular flows at high latitudes.

The model includes calculations of thermospheric circulation, electron density, and. Impact of gravity wave drag on the thermospheric circulation: implementation of a nonlinear gravity wave parameterization in a whole-atmosphere model Division II IAGA Special Sporon Book.

In the thermospheric block the model global distribution of the neutral gas temperature, of N 2, O 2, O, NO, N (4 S), and N (2 D) concentration, as well as the three-dimensional circulation of the neutral gas are calculated in the range from 80 to km in a spherical geomagnetic coordinate by: Abstract.

Numerical simulations of the thermospheric temperature and mass density variations have been performed with a whole atmosphere general circulation model (GCM) which includes all the atmospheric regions: troposphere, stratosphere, mesosphere, and : Hitoshi Fujiwara, Yasunobu Miyoshi, Hidekatsu Jin, Hiroyuki Shinagawa, Kaori Terada.

The validation of complex nonlinear numerical models such as the National Center for Atmospheric Research thermospheric general circulation model (NCAR TGCM) requires a detailed comparison of model predictions with data.

Thermosphere the layer of the upper atmosphere located between the mesopause—that is, the upper boundary of the mesosphere—and the base of the exosphere. On the average, the thermosphere extends from a height of about 80 km to a height of about km; these limits vary by ±10–20 percent.

The atmospheric circulation can be viewed as a heat engine driven by the Sun's energy, and whose energy sink, ultimately, is the blackness of space. The work produced by that engine causes the motion of the masses of air and in that process, it redistributes the energy absorbed by the Earth's surface near the tropics to the latitudes nearer the poles, and thence to space.

Journal of Atmospheric and Solar-Terrestrial Physics, Vol. 60, Issue. 14, p. The Thermospheric General Circulation Models (TGCM's) are three-dimensional, time-dependent models of the EARTH's neutral upper atmosphere.

The models use a finite differencing technique to obtain a self-consistent solution for the coupled, nonlinear equations of hydrodynamics, thermodynamics, continuity of the neutral gas and for the coupling.

The asymmetry is usually explained by the seasonal impact due to the seasonal changes in the thermospheric circulation. It is known that in summer the daytime background (solar-induced) circulation is directed equatorwards, and it is poleward in the winter hemisphere (e.g., Fuller-Rowell et al.

; Fuller-Rowell ).Cited by: [1] We investigated the relationship between the systematic annual and semiannual variations in the ionosphere and thermosphere using a combination of data. With regard to these parameters there have been serious discrepancies between observational indications and theoretical expectations.

It has also been used to compare model predictions with measurements made from various ground-based Fabry-Perot interferometer stations, incoherent scatter radar stations and the Dynamics Explorer satellites.

Three-dimensional models of the Mars thermospheric circulation show that planetary rotation has a significant influence on the wind, composition and temperature structure. There is upward flow on the day side, downward flow on the night side. Observations of the thermospheric temperatures near solar minimum from Viking showed a mean dayside.

Thermospheric wind data obtained from the Atmosphere Explorer E and Dynamics Explorer 2 satellites have been used to generate an empirical wind model for the upper thermosphere, analogous to the MSIS model for temperature and density, using a limited set of vector spherical harmonics.

The nonlinear evolution of thermospheric winds in an ionosphere-magnetosphere coupled model has been studied for the first time for a dynamic unstable auroral-arc environment.

The authors treat the problem using a multi-layer, quasi-three-dimensional model which averages in altitude the thermospheric dynamics over each layer. TIE-GCM simulated effects of the lower thermospheric residual circulation on thermospheric composition (O/N2): upwelling of the simulated lower thermospheric residual circulation greatly decreases O/N2 in the winter hemisphere but downwelling in summer slightly increases O/N2 at high latitudes.

This reduces the summer-to-winter gradient of O/N2. Is the Sun an agent of global change? Whether variable energy inputs from the Sun have anything to do with the Earth's weather and climate has been debated contentiously for more than a century.

In a National Academy of Sciences Panel on Solar Variability, Weather and Climate studied the issue. The Upper Atmosphere: Meteorology and Physics focuses on the study of the characteristics, movements, composition, and observations of the upper atmosphere.
