Hurricanes spin counterclockwise (like all low pressure centers in the northern hemisphere) because of the Coriolis Effect. Because the equator rotates faster than other areas of the Earth's surface, ...

Tornadoes do occur in the Southern Hemisphere, albeit at a greatly reduced frequency than in the Northern Hemisphere, primarily because it includes the U.S., which hosts about 75 percent of the ...

Usually, tornadoes in the U.S. rotate counterclockwise. Coriolis force, imparted due to the Earth’s rotation, causes air around low centers to circulate counterclockwise in the northern hemisphere.
