Fascinating idea that this might not be Galileo's GRS...but if you think about it this makes sense. Jupiter's atmosphere is so dynamic that it's ridiculous to think of the GRS as a permanent feature in terms of geological time.

I recall some simulations a few years ago that indicated that a Spot-like storm almost always arose given a Jovian planet's assumed atmospheric properties, rotation rate, etc. But, it apparently doesn't have to be the same Spot every time. My question is whether two or more of similar magnitudes could be sustained, or does one have to die before another can fully form?

James Gleick's book Chaos referenced a 1985 paper that showed how a GRS would appear on Jupiter. The photos from the book are amongst these animations. There are some pretty neat videos there.
