Clockwise Vs CounterClockwise

In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth.

It is definition of Wikipedia and it is true.On the other word , direction of clouds movement depends on their location on the earth. Generally speaking If a cyclone forms in northern hemisphere, winds which try to reach to the center of a low pressure incline to right.In southern hemisphere winds incline to left on their way toward the center of a low pressure.Thus , in northern hemisphere, clouds spin around the low pressure center anti-clockwise or counterclockwise, and in southern hemisphere, clouds rotate clockwise around center of a low pressure( depression).

Here is a cyclone over Iceland (Northern hemisphere)





Here is a cyclone over Pacific coast of Chile (Southern hemisphere)
