Cyclone
In meteorology, a cyclone can refer to one of several different meteorological phenomena. Due to ambiguity most weather forecasters avoid using the term cyclone without a qualifying term.
The term normally refers to a wind and rain storm associated with a region of atmospheric low pressure. The cyclonic winds rotate around a common center. Rotation is counter-clockwise in the northern hemisphere, or clockwise in the southern hemisphere. The rotation is caused because air moving between the tropics and the poles is affected by the rotation of the earth. The storms are termed Hurricanes, typhoons or tropical cyclones, depending where they form and how strong they are.
In North America, a tornado may also be called a cyclone. This usage has gone out of favour in recent years as professional weather forecasters have avoided using the term in this way.

In industry, a cyclone may refer to any of a number of different types of vortex separators. These devices use rotational effects and gravity to separate mixtures of solids and fluids. Because of different densities the heavier material is flung to the outside edge of the vortex while the lighter material is concentrated in the centre of the vortex.
Applications include:
- Removing dust from air
- Separating oil and gas
Cyclone is a dialect of the C computer programming language.
