See mid-latitude cyclone.

A storm center which forms on and then moves along a front.

cyclone that forms and moves along a front, producing by its circulation a wavelike deformation of the front.

a deep low pressure system found in the mid to high latitudes

An extratropical cyclone that forms and moves along a front. The circulation of winds about the cyclone tends to produce a wavelike deformation on the front. An appreciation for the energy of a wave cyclone can be realized by recognizing the fact that an average wave cyclone dumps at least 200,000,000,000,000 (200 trillion) pounds of water on Earth's surface during its lifetime of several days! As a little side note: A wave cyclone in March of 1776 forced the British to cancel a massive amphibious assault at Dorchester heights, south of Boston, where General Washington held a well-fortified position. The storm kept Dorchester heights from becoming a bloody, historic battlefield, such as Lexington, Concord, and Bunker Hill

(Also called wave depression.) A cyclone that forms and moves along a front. The circulation about the cyclone center tends to produce a wavelike deformation of the front. The wave cyclone is the most frequent form of extratropical cyclone (or low). It was the purpose of the wave theory of cyclones to explain its life cycle.

A storm or low-pressure center that moves along a front.

A cyclone which forms and moves along a front. The circulation around the cyclone's center produces a wavelike deformation on the front. May also be call a migratory cyclone or low.
