Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe gales, … See more The term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the … See more Surface pressure and wind distribution The windfield of an extratropical cyclone constricts with distance in relation to surface level pressure, with the lowest pressure being found near the center, and the highest winds typically just on the cold/poleward side … See more There are two models of cyclone development and life cycles in common use: the Norwegian model and the Shapiro–Keyser model.

WebExtratropical cyclones are cyclones that form outside of the tropics. They form in mid-latitude zones, typically between 30 o and 60 o latitude.
