This is a pretty odd request for a VGM forum, but I figured I'd ask it considering how in-depth some of the scientific talk around here becomes due to certain people's professions.

A general interest of mine since I was a child has been weather, in particular bad weather like thunder, lightning, thunderstorms and tornados. Watching the movie Twister for the past few days, I started thinking about getting some DVD's with some actual, factual footage and facts. I was wondering if anyone had an opinion/knew of mini-series that would be up my (tornado) alley?
