Belts are low pressure systems and zones are high pressure systems wrapped around the entire planet. The bands near the equator of Saturn are very large. Small circular systems or storms also occur periodically in Saturn's atmosphere.

Zones are high pressure systems and belts are low pressure systems. They flow in opposite directions around the entire planet. There are also smaller disturbances or storms within Saturn's zones and belts, similar to but much less powerful than Jupiters Great Red Spot.
