The phenomenon is caused by low atmospheric pressure, which generates clouds with rain and strong winds. An extratropical cyclone forms in areas where there is a contrast between warm and cold air masses. Usually, when it hits a region, it also brings a cold front with it.
Extratropical cyclones are common events on the Brazilian coast, formed in the Atlantic and more frequent during the fall and winter seasons. The lower the atmospheric pressure, the stronger the winds and storms caused and influenced by the phenomenon.
