The direction of
that spin depends on what hemisphere of the world the hurricane is brewing in. A
hurricane's spin and the spin's direction are determined by a super-powerful
phenomenon called the "Coriolis effect."
The particles
heading away from the equator are traveling at higher speeds than the ones
closer to the poles. Because the globe is spinning, air and water therefore
don't follow a straight path north or south. Instead, anything traveling
northward in the northern hemisphere gets pushed toward the right.
Particles
traveling from the equator to the south experience a similar curve in the
opposite direction. It effects things like wind, ocean currents, airplanes,
missiles, but doesn’t effect toilets or sinks.”
(In case you were wondering, that would be better referred to as
“ambient swishing.”)
