Do cyclones spin clockwise or anti clockwise in the southern hemisphere?

Answer:
Most spin clockwise, but not all of them. Tornadoes are on the margin of the scale at which the Coriolis Force operates, so under certain conditions tornadoes can rotate against the weak Coriolis Force that exists at the mesoscale. I believe the percentage of tornadoes that do this is around 10.
