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.
The sweet gale.
A severe, rotating tropical storm with heavy rains and cyclonic winds exceeding 74 mi (119 km) per hour, especially such a storm occurring in the Northern Hemisphere. Hurricanes originate in the tropical parts of the Atlantic Ocean or the Caribbean Sea and move generally northward. They lose force when they move over land or colder ocean waters.
A violently rotating column of air extending from a cumulonimbus cloud to the Earth, ranging in width from a few meters to more than a kilometer and whirling at speeds between 64 km (40 mi) and 509 km (316 mi) per hour or higher with comparable updrafts in the center of the vortex. The vortex may contain several smaller vortices rotating within it. Tornadoes typically take the form of a twisting, funnel-shaped cloud extending downward from storm clouds, often reaching the ground, and dissolving into thin, ropelike clouds as the tornado dissipates. Tornadoes may travel from a few dozen meters to hundreds of kilometers along the ground. Tornadoes usually form in the tail end of violent thunderstorms, with weaker funnels sometimes forming in groups along a leading squall line of an advancing cold front or in areas near a hurricane . The strongest tornadoes, which may last several hours and travel hundreds of kilometers, can cause massive destruction in a relatively narrow strip along their path. The causes of tornado formation are not well understood.
Allowing movement or action only at a low speed:
A storm with high winds or violent gusts but little or no rain. Winds with speeds up to 241 km (149 mi) per hour have been recorded during windstorms.
A violent storm with high winds, esp. one accompanied by rain, hail, or snow
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.
