An Overview of Motions in Uranus' Atmosphere
Motions in the atmosphere include wind. The major winds in the Uranian atmosphere are the zonal winds
which consist of westward flowing zones and eastward flowing belts.
The other major means of motion in the atmosphere is by diffusion. There is a continual circulation within the atmosphere from the top to the bottom. Ethane diffuses down through the atmosphere and collects at the bottom where it breaks apart and becomes methane. The methane returns to the top of the atmosphere by diffusion. This constant breakdown and assembly of methane and ethane is part of the evolution of Uranus and affects its weather.

The mesosphere of Uranus is a region of balance between warming and cooling. That essentially means that nothing happens there. Except for diffusion, the atmosphere is still. Upper reaches of the atmosphere,...more
