One of the many meteorological websites among which I’ve been flipping over the past few days (I’ve unfortunately forgotten which link it was) tossed out a nifty little factoid of which I had not been aware:  The reason the sky looks so especially blue after a hurricane has come through is the abundance of more oxygenated air that the storm scoops up from lower down and tosses into the upper atmosphere.

I’ve noticed the phenomenon myself numerous times, but never really stopped to think about the cause.  Pretty cool.
