Infrared storms on Jupiter

Infrared storms on Jupiter

Fig. 9.6 . The heat of two continent-sized storms (top) is detected in this infrared image. The bright plumes are attributed to storm systems triggered in Jupiterís deep clouds of water ice that move upward in the atmosphere and inject a fresh mixture of ammonia ice and water above the visible cloud tops. Models of the disturbance indicate that the associated jet stream extends deep in the atmosphere, at more than 100 kilometers below the cloud tops, and that the jet stream moves at a speed of about 600 kilometers per hour. This image was obtained from NASAís ground-based InfraRed Telescope Facility, abbreviated IRTF, in Hawaii on 5 April 2007. (Courtesy of NASA/JPL/IRTF.)
