The Atmosphere 

Uranus has a thick atmosphere comprised of 83% hydrogen, 15% helium, 2% methane, and trace amounts of acetylene as well as other hydrocarbons. Much like on Neptune, Uranus has a bluish hue on the surface, the result of absorption of red light by the methane gas.

Similar to the other gas giants in our solar system (such as Saturn and Jupiter), the surface of Uranus has extremely high wind speeds (clocked to be 40 to 160 meters per second, which is 90 to 360 miles per hour) with layers of latitudinal clouds that line the planet. Unlike on Neptune, the winds near the mid-latitudes blow with the direction of the planet's rotation. However, near the equator, experiments have determined slower winds blowing in the opposite direction.
