Extratropical cyclone: A storm that forms outside the tropics, sometimes as a tropical storm or hurricane changes. See table below for differences between extratropical and tropical cyclones.
Extratropical Cyclone - a cyclone in the middle and high latitudes often being 2000 kilometers in diameter and usually containing a cold front that extends toward the equator for hundreds of kilometers ...
EXTRATROPICAL CYCLONE Any cyclone that is no longer tropical in origin. Generally considered to be a migratory frontal cyclone found in the middle and high latitudes.
Extratropical cyclone
A cyclone (low pressure system) that possesses a cold core. Any low pressure system that forms outside the tropics is extratropical.
EXTRATROPICAL CYCLONE
Any cyclone not of tropical origin. Generally considered to be a migratory frontal cyclone found in the middle and high latitudes.
Extratropical cyclones lie somewhere in between tropical cyclones and mid-latitude cyclones, drawing a portion of their energy through the evaporation and condensation of ocean water, ...
Extratropical Cyclone- A cyclone that forms outside of the tropics.
Evaporation- The change in a substance from a liquid or solid state to a gaseous state.
Eye- The roughly circular area of relatively calm weather at the center of a hurricane.
Extratropical cyclones that form on the downwind (lee) side of a mountain chain. In the United States, they frequently form on the eastern side of the Rockies and Sierra Nevadas.
Leeward
The side away from the wind. Compare windward.
EXTRATROPICAL CYCLONE - Is a very large scale weather system that develops in the mid and upper latitudes outside the tropics, hence the name "extratropical".
the belt of extratropical cyclones.
The trade winds from both hemispheres converge towards the doldrums and a zone of low pressure, the equatorial trough, that girdles the earth.
Wave cyclone An extratropical cyclone that forms and moves along a front. The circulation of winds about the cy clone tends to produce a wavelike deformation on the front.
Storms range in scale from tornadoes and thunderstorms to tropical cyclones to synoptic-scale extratropical cyclones.
Cyclogenesis and Cyclolosis "Cyclogenesis" and "cyclolosis" are terms used by meteorologists to refer to stages of an extratropical cyclone or low pressure system.
mesoscale - Pertaining to atmospheric phenomena having horizontal scales ranging from a few to several hundred kilometers, including thunderstorms, squall lines, fronts, precipitation bands in tropical and extratropical cyclones, ...
Comma cloud: A features of extratropical cyclones observed in satellite pictures where the cloud system resembles the comma punctuation mark.
Condensation: Change from water vapor to liquid water.
extratropical low (sometimes called extratropical cyclone, extratropical storm)—Any cyclone that is not a tropical cyclone, usually referring to the migratory frontal cyclones of middle and high latitudes.
EXTRATROPICAL- A low pressure system that did not develop in the tropics. Extratropical cyclones have a baroclinic energy regime. Extratropical can also be in reference to a tropical system that is losing tropical characteristics.
Subtropical Cyclone: A non-frontal low pressure system that has characteristics of both tropical and extratropical cyclones.
Storm
(1) An atmospheric disturbance involving perturbations of the prevailing pressure and wind fields, on scales ranging from tornadoes (1km across) to extratropical cyclones (2000-3000km across). (2) Wind with a speed between 48 and 55 knots.
south or southwest along the Atlantic seaboard and Great Lakes; these are especially common during the spring months.

of the atmosphere, especially affecting the Earth's surface, and strongly implying destructive and otherwise unpleasant weather. Storms range in scale from tornadoes and thunderstorms to tropical cyclones to synoptic-scale extratropical cyclones.
Also, because cyclones are nearly always accompanied by inclement (often destructive) weather, they are frequently referred to simply as storms. See tropical cyclone, extratropical cyclone; compare trough.
This generally occurs when there are significant storms, such as tropical and extratropical cyclones.
