Jupiter's Great Red Spot Is Shrinking
cjstaples noted a CNN story proclaiming that
Jupiter's signature red spot is shrinking. Over a 10 year study, the giant storm lost just over half a kilometer per day for a total loss of about 15%. Scientists know about shrinkage, right?
Storms are created by temperatures differences, which are in turn created by sunlight warming different areas at different rates. So yes, the same kinds of things will happen on Jupiter, if nothing else based on the temperature difference from the day to the night side. The real question is, why has the Red Spot been so stable for so long?
Think about it; surface features shouldn't effect warming rates since all solar radiation is absorbed long before it gets to the surface. Pockets of atmosphere will absorb heat at different rates, but those pockets aren't stationary. That leaves complex, self-correcting fluid dynamics or massive surface features that significantly change the wind patterns hundreds or thousands of miles up or something we just don't understand yet. All of which are pretty interesting.
You are overlooking one important energy source: Jupiter itself. Because of ongoing differentiation, Jupiter produces about twice as much energy as it receives from the Sun. Given this and the fact that this source is coming from below rather than above, it is likely the more important contribution to the dynamics of the atmosphere.

Don't tell this to the alliance of East Coast liberals who fought the building of the largest wind farm in the world outside of Martha's Vinyard. I guess clean energy is good as long as only poor people have to put up with the effects.
