Some properties of upper atmosphere dynamics

Reviews of Geophysics, 1978
Composition and temperature data from satellite measurements and from radar backscatter observations show that dynamics is a major key in our understanding of the upper atmosphere. Individual gases are tracers of wind fields which in turn are driven by the energy and momentum sources of the complex magnetosphere‐thermosphere‐lower atmosphere system. As

Gas dynamics of a rocket plume in the upper atmosphere

Journal of Russian Laser Research, 2010
We study the expansion of a rocket exhaust plume in the direction perpendicular to the rocket motion. We compare numerical calculations with a self-similar approximation for a strong cylindrically symmetric explosion and show that, if the rocket velocity V∞ is high enough and exceeds the sum of the exhaust gas velocity Ve and the sound velocity Vs (V∞>

On the dynamics of strong temperature disturbances in the upper atmosphere of the Earth

Physics of Fluids A, Fluid Dynamics, 1989
The dynamics of the cooling of a strongly heated spherically symmetric cavity produced by an explosion in the upper atmosphere is investigated, allowing for the gas motion during the heat conduction. Conditions for a self-similar cooling process are found, and the corresponding self-similar dynamics equations are solved. The characteristic cooling time
