The mid-latitude thermosphere

VORTICITY AND DIVERGENCE IN THE HIGH - LATiTUDE UPPER THERMOSPHERE

Measurements made from the Dynamics Explorer-2 satellite in November 1981 through January 1982 and November 1982 through January 1983 have been analyzed to determine the divergence and vertical component of vorticity of the high-latitude n utral wind field in the upper thermosphere for quiet (Kp <3) and active (3+ < Kp <6) geomagnetic conditions and for both northern (winter) and southern (summ...

Evidence of meso-scale structure in the high-latitude thermosphere

There is a widely held assumption that the thermospheric neutral gas is slow to respond to magnetospheric forcing owing to its large inertia and therefore, may be treated as a steady state background medium for the more dynamic ionosphere. This is shown to be over simplistic. The data presented here compare direct measurements of the thermospheric neutral winds made in Northern Scandinavia by F...
