<P> The South Tropical Region includes the South Equatorial Belt ( SEB ) and the South Tropical Zone . It is by far the most active region the planet , as it is home to its strongest retrograde jet stream . The SEB is usually the broadest , darkest belt on Jupiter ; it is sometimes split by a zone ( the SEBZ ) , and can fade entirely every 3 to 15 years before reappearing in what is known as an SEB Revival cycle . A period of weeks or months following the belt 's disappearance , a white spot forms and erupts dark brownish material which is stretched into a new belt by Jupiter 's winds . The belt most recently disappeared in May 2010 . Another characteristic of the SEB is a long train of cyclonic disturbances following the Great Red Spot . Like the NTropZ , the STropZ is one of the most prominent zones on the planet ; not only does it contain the GRS , but it is occasionally rent by a South Tropical Disturbance ( STropD ) , a division of the zone that can be very long - lived ; the most famous one lasted from 1901 to 1939 . </P>
