The Red Spot: sure looks like there is something going on below the atmosphere. Something at least semi-permanent sticking up from the solid surface. Is there a solid surface?

Several years ago I recall that a group did a simulation of planetary gaseous circulation, and a stable "storm" like the Great Red Spot turned out to be a normal condition for an atmosphere like Jupiter's. That's about all I remember.
