In the northern hemisphere, the vast majority of tornadoes (more than 95 percent) rotate counter-clockwise–the same spin as a low pressure system. At low levels, air spirals into a tornado in a large ...

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 ...

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, ...

Venus rotates clockwise, opposite most planets, a phenomenon called retrograde rotation. A day on Venus is longer than its year, and the sun rises in the west. Scientists believe a collision or ...
