Earth:Atmospheric super-rotation
From HandWiki
Short description: State where a planet's atmosphere rotates faster than the planet itself
Atmospheric super-rotation is the state where a planet's atmosphere rotates faster than the planet itself. The atmosphere of Venus is one example of extreme super-rotation; the Venusian atmosphere circles the planet in just four Earth days, much faster than Venus' sidereal day of 243 Earth days.[1] Atmospheric super-rotation has also been observed on Titan, the largest moon of Saturn.[2]
It is believed that the Earth's thermosphere has a small net super-rotation in excess of the surface rotational velocity, although estimates of the size of the phenomenon vary widely.[3][4][5] Some models suggest that global warming is likely to cause an increase in super-rotation in future, including possible super-rotation of surface winds.[6][7]
