Thermospheric wind
 - University of California, Berkeley)
A thermal wind system develops with the wind toward the poles in the upper level and winds away from the poles in the lower level. The coefficient ΔT 2 0 ≈ 0.004 is small because Joule heating in the aurora regions compensates that heat surplus even during quiet magnetospheric conditions. Visa mer The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, … Visa mer Energy budget The thermospheric temperature can be determined from density observations as well as from direct satellite measurements. The temperature vs. altitude z in Fig. 1 can be simulated by the so-called Visa mer In contrast to solar XUV radiation, magnetospheric disturbances, indicated on the ground by geomagnetic variations, show an unpredictable impulsive character, from short … Visa mer • Aerial perspective • Aeronomy • Air (classical element) • Air glow Visa mer It is convenient to separate the atmospheric regions according to the two temperature minima at an altitude of about 12 kilometres (7.5 mi) (the tropopause) … Visa mer Within the thermosphere above an altitude of about 150 kilometres (93 mi), all atmospheric waves successively become external waves, and … Visa mer A contraction of the thermosphere has been observed as a possible result in part due to increased carbon dioxide concentrations, the strongest cooling and contraction occurring in that layer during solar minimum. The most recent contraction in … Visa mer WebbThis paper will discuss two aspects of the thermospheric neutral wind system which have been reasonably well documented by experimental data.
