The circulation of Jupiter's atmosphere is discussed in Section 1.5, and the movies below document various scales of atmospheric motion, including rotation of the Great Red Spot. The clouds forming the opaque 'surface' to Jupiter's atmosphere are presumed to be created by ammonia (NH3) condensing out of a vapour to form tiny suspended crystals of ammonia ice.
