The main atmospheric jet streams were present during both Voyager encounters, with some changes in velocity.
The Great Red Spot, the white ovals, and the smaller white spots at 41°S, appear to be meteorologically similar.
The formation of a structure east of the Great Red Spot created a barrier to the flow of small spots which earlier were circulating about the Great Red Spot.
The ethane to acetylene abundance ratio in the upper atmosphere appears to be larger in the polar regions than at lower latitudes and appears to be 1.7 times higher on Voyager 2 than on Voyager 1.
An ultraviolet map of Jupiter shows the distribution of absorbing haze. The polar regions are surprisingly dark, suggesting that the absorbing material must be at high altitudes.
Equatorial ultraviolet emissions indicate planet-wide precipitation of charged particles into the atmosphere from the magnetosphere.
The high-latitude ultraviolet auroral activity is due to charged particles that originate in the Io torus.
Satellites and Ring System
The ring consists of a bright, narrow segment surrounded by a broader, dimmer segment, with a total width of about 5800 kilometers.
The interior of the ring is filled with much fainter material that may extend down to the top of the atmosphere.
