By hacking climate models originally built for Mars, scientists have made the surprising prediction that Pluto has winds of up to 225 mph. It also appears to be much simpler than other planets which have atmospheres.
I dunno, though. Using something even the scientists admit is a limited tool, built more than a decade ago, to predict something as complex as weather... well, it doesn't seem all that reliable to me. Of course, being a member of The Vast Right Wing Conspiracy, I tend to automatically be suspicious when scientists start using models to predict anybody's weather. Call it the Al Gore Principal, if you will.
