Shpoop

I've always held this as a widely regarded truth...after all, there is a Simpsons episode about it! But I have a page-a-day calendar called "Fact or Crap?" and the question today pertained to this. I almost didn't look for the answer, knowing what it would be, but it turned out to be Crap! This is what it said:

"There is somethign called the Coriolis force, which, in short, is what happens when air flows from high to low pressure under the earth's rotation. This deflects wind to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The effect is noticeable, however, only for large-scale motions, such as weather conditions."

I can't say im fully convinced...has anyone here studied this formally and have the answer?
