Discover dark features in Jupiter's atmosphere called "hot spots," and their connection to large-scale atmospheric waves. David Choi describes his research on hot spots clearings in Jupiter's atmosphere that appear bright in infrared light. Analysis of data from the Cassini mission in 2000 reveal how Rossby waves that move vertically in the atmosphere may be responsible for producing hot spots. In 1995, the Galileo probe descended into Jupiter's atmosphere and took measurements of a hot spot. The recent identification of the role of Rossby waves will help researchers reexamine Galileo data in the context of Jupiter's global climate.
