Could somebody say a bit more about what we are looking at here. Are we looking, as it appears, at a large proportion of the whole disc of Saturn, or are we looking at a round photograph of what could be a very small part of the whole disc of Saturn? It must be the latter, right?

Benard cells are a packing phenomenon, so they rely on the cooperative effect through the lattice to form. I assume this Saturn jet stream basically has a latitudinal instability, and the interference effect from having it recycle either adjusts the wavelength, or adjusts the position of the circumference, so that it finds a consistent re-entrant pattern. A thing that would be very cool is if, as the northern-hemisphere summer goes on, enough more heat enters that part of the atmosphere that it drives the stream differently, the natural wavelength of the instability changes, and the belt goes into a new polygon like a pentagon, perhaps with a period of chaos or something else complicated in the transition. But, I have never done a real fluid-dynamics calculation, so this is of course completely idle on my part.
