Springtime on Saturn

Storm Chasing on Saturn with Cassini [viz. cf.] - "The sun is slowly rising over Saturn's north pole, exposing an immense six-sided hurricane. The storm, big enough to swallow four Earths, was first spotted by the Voyager missions in the early 1980s. [Cassini] will be passing directly over the north pole with its cameras pointing down later this month." (previously 1,2)

Ah, nice to get an explanation for the hexagon hurricane. What a magnificent phenomenon.

Cassini may be the one thing in the solar system more impressive than Saturn itself. wow.

APOD recently shared this 2012 Cassini image of the hexagon which is lovely for its subtle details.

I'm not satisfied with the NYT article's explanation for the hexagon. I can understand how friction in the moving atmosphere would cause a standing wave. But why 6 sides? Why not 3? or 200?

Nelson, it's a function of the difference in rotation rates between the two bands - in this case, the planet and the jetstream. There's a really nice tabletop model for this - take a look at this old comment.

Thanks RedOrGreen. Apparently different speeds produce different shapes. The video in the linked comment is gone, here's another video of the simulation.

First off: Whoa, crazy, beautiful. Nicely done, Saturn.

Secondly: That was really well produced. Kudos to the NYTs.
