Hope this one hasn't been discussed...I'm in a bit of a hurry and wanted to post this before going to school. I was talking to a friend about the southern hemisphere, of which I know nothing, and mentioned the old factoid about the water in the toilets moving in the opposite direction of the water in the northern hemisphere. So, I googled something like "toilet Southern hemisphere" and found a lot of information on the Coriolis Effect. The effect can't occur over small areas, e.g., toilet bowls, but my question is what are the applications of where the effect actually does occur? Are there tornadoes in the southern hemisphere? Here's one pasting of something read last night:

Fred W. Decker, professor emeritus of oceanic and atmospheric science at Oregon State University notes, however, that the Coriolis effect may actually have little to do with the behavior of real-world sinks and tubs...

Just wondering,
