Imagine the earth is one huge skating rink. You're at the North Pole and decide to skate down to the equator. You might think that you would travel
in a straight line, but your path would in fact be curved, because of the rotation of the earth.
Air moves towards low pressure systems and away from high pressure. They might normally travel in a straight line but instead get spun by the
earth's rotation. Called the Coriolis Effect.
