Yes, Tucson has more variability. Water vapor acts as a thermostat. It's molecular weight of 18 g/mole is lighter than air (28.96 g/mole), thereby causing air to be more buoyant and more likely to convect. This convective mixing inhibits extremes and forms clouds. Synoptic-scale weather develops from energy conversions along fronts or gradients. "Global warming" decreases these gradients, because there are less extremes (warming the poles faster than the tropics). That's why all this jargon about extreme weather from "global warming" is hog wash. I'm amazed how many Ph.D.'s don't seem to grasp this and are inconsistent. It just shows a bias. Granted, I agree, most climate blogs are biased both ways. I won't argue that :) Many events of extreme floods and droughts are caused by blocking regimes (large, persistent ridges of high pressure). Most climate models I've studied diminish blocking regimes (e.g., the negative component of the North Atlantic Oscillation...http://www.met.rdg.ac.uk/~swr01tjw/pubs/naoregimes.pdf). Again, blaming extreme ridges of high pressure on global warming either illustrates a misunderstanding of dynamics and/or a bias.
