What is an extra tropical cyclone

An extratropical cyclone, also known as a mid-latitude storm, is a low-pressure system that develops at latitudes outside the tropics, according to the United Nations Office for Disaster Risk Reduction (UNDRR). They are often associated with cold, warm and occluded fronts and can occur over land or sea.

It is named for the location where the cyclone occurs, which typically occurs at mid-latitudes between 30° and 60° latitude from the equator.

Storms of this type are driven by temperature differences where two air masses meet and create a “front.” That is, they get their energy from horizontal temperature contrasts that exist in the atmosphere, explained the National Park Service (NPS) of the United States.

The United Nations office notes that “the total life cycle of an extratropical cyclone, from its birth (genesis) through its development to its decay (lysis), can occasionally be more than 10 days, although it is more common to range from 2 to 5 days.”
