An extratropical cyclone. Extratropical cyclones are centers of low atmospheric pressure that form in medium and high latitudes, outside the tropics, due to the contrast between a cold air mass and a warm air mass. They are associated with a cold front and their winds are weaker and shorter than tropical cyclones.
