It's amazing how different the atmosphere looks depending on whic filter is used to view it:

Another atmosphere thingy...

is a very cool image of Pandora and the almost edge-on rings. But look at Saturn in the background - very close to the terminator. Those shadings look like cloud shadows to me. I don't recall them ever being reported before on Saturn, though Voyager 2 saw then at Neptune.

These cloud ripples evoke water flowing in a river over an underwater obstacle. If we keep with this analogy, there may be some invisible disturbance under the visible cloud layer, perhaps a kind of cumulus cloud. Such ripples can form on Earth above mountains or cumulus, but they are usually not visible, unless there is a continuous layer of clouds.
