Futhermore, the cloud structure is higher in the centre by more than 10 km and tilted towards one side, something like a crooked spiral staircase. What seems to be happening is that wet air from the deep atmosphere is rising rapidly in a relatively narrow region in the centre of the GRS, and then spraying out above the tops of the ammonia clouds while rotating, rather like a giant garden sprinkler. In some ways this is similar to what happens in a terrestrial hurricane, but the Jovian storm is much bigger than the entire Earth. Rings, even Rings Jupiter's main ring is a thin strand of material encircling the planet. The diffuse innermost boundary begins at approximately 123,000 km.
Satellites thus seem to affect the structure of even tenuous rings like that found at Jupiter.
