Churning Clouds on Jupiter
Explanation: Where is Jupiter's ammonia? Gaseous
ammonia was expected to be seen in
Jupiter's upper atmosphere by the orbiting
Juno spacecraft -- but in many clouds is almost absent. Recent Juno data, however, gives some clues: some high-level clouds appear to be home to an unexpected type of electrical discharge dubbed
shallow lightning. Great charge separations are needed for
lightning, which might be created by colliding mushballs lifted by rising updrafts of gas. Ammonia and water stick to these
mushballs which rise until they get too heavy -- after which they
fall deep into
Jupiter's atmosphere and melt. By this process, ammonia found missing from <a hre="ap200106.html">Jupiter's upper atmosphere</a> reappears below.
Pictured by Juno, churning clouds on Jupiter show not only mesmerizing complexity but some high-level, light-colored
pop-up clouds.
Understanding atmospheric dynamics on Jupiter gives valuable perspective to similar atmospheric and
lightning phenomena that occur on our home Earth.
