Saturn - Ribbon-like Wave Structure in Atmosphere
March 21, 2003
A view of Saturn's clouds extending from 40` to 60` N latitude shows a ribbon-like wave structure in the south with small convective features marking a westward jet in the north. This image was obtained on November l0, l980 when Voyager l was at a distance of 3,500,000 kilometers (2,200,000 miles) from Saturn. The smallest resolved features in this photograph are 65 kilometers (40 miles) in diameter. Images with similar resolution indicate that Saturn's circulation is somewhat different from Jupiter's. The maximum westward velocities seen on Saturn are located in the middle of the darker regions, while on Jupiter they are located at the poleward interface between belts and zones.
