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.

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 ...

Mike Moss: It is true that large scale low pressure systems in the Southern Hemisphere have winds that spiral into them in a clockwise manner, as opposed to the counterclockwise flow around lows in ...

As bizarre as Venus appears today --- a hellish cloud-cloaked world of extraordinary surface pressures and surface temperatures not fit for man or beast --- it is also one of only two full-sized ...
