PIA01365: Saturn's Northern Hemisphere


Saturn’s Northern Hemisphere

Caption:

This false color picture of Saturn's northern hemisphere was assembled from ultraviolet, violet and green images obtained Aug. 19 by Voyager 2 from a range of 7.1 million kilometers (4.4 million miles). The several weather patterns evident include three spots flowing westward at about 15 meters-per-second (33 mph). Although the cloud system associated with the western-most spot is part of this flow, the spot itself moves eastward at about 30 meters-per-second (65 mph). Their joint flow shows the anti-cyclonic rotation of the spot, which is about 3,000 km. (1,900 mi.) in diameter. The ribbon- like feature to the north marks a high-speed jet where wind speeds approach 150 meters-per-second (330 mph).
