Uranus' Troposphere
The troposphere of Uranus is where the
methane clouds are. Clouds form in regions of strong atmospheric motion when condensation takes place. The troposphere is the region rapidly stirred by vertical
motions.
The troposphere is warmed by the sun, warmed by Uranus' interior, and is cooled due to re-radiation to space by the gases of the atmosphere. For a picture showing how the temperature changes in this region, click here.

As on Earth, the atmosphere of Uranus consists of a troposphere, stratosphere, mesosphere, and thermosphere. The troposphere is the region where the visible clouds are to be found. The stratosphere, as

Besides methane, Uranus' atmosphere contains even more complex molecules. These molecules form layers of smog over the clouds of Uranus, as shown in the picture.

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,

On Uranus, as on Jupiter, the winds in the belts and zones blow first in one direction, then in the other direction. The clouds rise up in a belt, and drop down in a zone, as shown in this picture. This

The clouds on Uranus, like Jupiter, are divided into stripes. On Uranus the stripes are hard to find. The left picture shows the north pole of Uranus. In this picture only the smog can be seen. The clouds,
