thermosphere gusting

30 January 2016

William Thompson forwarded this link – http://eos.org/research-spotlights/scientists-detect-wisps-of-wind-in-space … on a paper in the Journal of Geophysical Research: Space Physics (January 2016). It is about the way the aurora seems to distort weather at thermospheric altitudes at latitudes (polar and near polar). Aurorae stir up storms at an altitude of 250km – but where does the wind blow? The thermosphere is on the edge of space. It begins at 85km altitude and extends to 1000km high. This is the region of the atmosphere where the space station orbits, and various satellites. However, it is still an integral part of Earth's atmosphere. Charged particles from space bombard the top of the atmosphere and churn up the thermosphere creating waves that resemble gusts of wind.
