The Great White Spot and disturbances in Saturn's equatorial atmosphere during 1990

A giant storm, the Great White Spot, erupted at the end of September 1990 as a localized, bright cloud system close to Saturn's equator. Its evolution produced a complex planetary disturbance which affected the whole equatorial region a month later. Similar spots have appeared approximately once every saturnian year (about 30 Earth years), implying that a seasonal change—in solar heating, for example—may be responsible for their occurrence.
