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.

Uranus' Tropospheric Temperature Profile

This is the temperature profile of Uranus' troposphere. The temperature becomes cooler with height until the tropopause, or "top" of the troposphere is reached. The tropopause is defined to be the altitude...more

An Overview of Uranus' Atmospheric Structure

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...more

Uranus' Atmospheric Hazes

Besides methane, Uranus' atmosphere contains more sophisticated atmospheric molecules such as ethane gas, acetylene, and diacetylene. All these molecules form layers of haze at different altitudes high...more

Uranus' Mesosphere

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

Altitude Variations of the Belts & Zones

On Uranus, as on Jupiter, the winds in the belts and zones blow first in one direction, then in the opposite direction. Wind blows east in a belt, and west in a zone. The clouds rise up in a belt, and...more
