Jupiter's atmosphere shows as alternation bands of light, regions, named zones, and dark regions, called belts, which are parallel to the equator.  The zones are higher in altitude and lower in temperature than the belts. The zones bring energy to the surface of this planet, and then calm down and sink again. 

       The surface pressure on Jupiter is 20–200 Pa (cloud layer).  The common gases on Jupiter include 86% Hydrogen, and 13 % Helium.
