Part of speech:
A large-scale system of winds that spiral in toward a region of low atmospheric pressure. A cyclone's rotational direction is opposite to that of an anticyclone. In the Northern hemisphere, a cyclone rotates counterclockwise; in the Southern hemisphere, clockwise. Because low-pressure systems generally produce clouds and precipitation, cyclones are often simply referred to as storms. &diamf3; An extratropical cyclone is one that forms outside the tropics at middle or high latitudes. Extratropical cyclones usually have an organized front and migrate eastward with the prevailing westerly winds of those latitudes. &diamf3; A tropical cyclone forms over warm tropical waters and is generally smaller than an extratropical cyclone. Such a system is characterized by a warm, well-defined core and can range in intensity from a tropical depression to a hurricane.
When warm air rises, the atmosphere is considered unstable. When the air is cooler than the surrounding air, it will sink and the atmosphere is said to be stable.

Allowing movement or action only at a low speed:

Characterized by speed of motion; rapid; swift
Coming, occurring, or accomplished quickly:
A violent cyclonic storm occurring in the western Pacific Ocean.
A circular, spiral, or helical motion in a fluid (such as a gas) or the fluid in such a motion. A vortex often forms around areas of low pressure and attracts the fluid (and the objects moving within it) toward its center. Tornados are examples of vortexes; vortexes that form around flying objects are a source of turbulence and drag.
