The variability of Joule heating, and its effects on the ionosphere and thermosphere [PDF]
Annales Geophysicae, 2001 A considerable fraction of the solar wind energy that crosses the magnetopause ends up in the high-latitude thermosphere-ionosphere system as a result of Joule heating, the consequences of which are very significant and global in nature.
