“This Saturn storm behaved like a terrestrial hurricane - but with a twist unique to Saturn,” said Andrew Ingersoll, a Cassini imaging team member based at the California Institute of Technology, Pasadena, who is a co-author on the new paper in the journal Icarus. “Even the giant storms at Jupiter don’t consume themselves like this, which goes to show that nature can play many awe-inspiring variations on a theme and surprise us again and again.”
Earth’s hurricanes feed off the energy of warm water and leave a cold-water wake. This storm in Saturn’s northern hemisphere also feasted off warm “air” in the gas giant’s atmosphere. The storm, first detected on Dec. 5, 2010, and tracked by Cassini’s radio and plasma wave subsystem and imaging cameras, erupted around 33 degrees north latitude.
