A new extratropical cyclone hit the country last Wednesday (27), with winds between 35km/h and 45 km/h in the coastal area of Santa Catarina and the state of Paraná.
According to information from INMET (National Institute of Meteorology), the phenomenon moves quickly towards the high seas, but until night in the South region.
During its training, the phenomenon caused strong winds over Rio Grande do Sul, with 89.3 km/h in Bagé, 85.0 km/h in Erechim, 80.6 km/h in Palmeira das Missões and 77.8 in Porto Alegre.
According to information from Nottus, new instabilities must organize themselves between the interior of the continent and the . On Friday (29), these new areas advance between Rio Grande do Sul and Mato Grosso do Sul, causing some rain showers.
There is also a risk of lightning and gusts of wind up to 55 km/h following the rain, but there is no risk of storms.
What is the difference between a cyclone and a tornado?
According to Inmet, the extratropical cyclone is a common phenomenon in Brazil and occurs from the collision between a mass of cold air and a mass of hot air. Its scale is much larger, and its intensity varies depending on the occurrence of strong winds, storms and microexplosions — high-speed discharges of cold air that, upon reaching the ground, generate significant damage at the point of impact.
smaller, characterized by the presence of the so-called “funnel cloud”. Due to its intensity and rapid formation, it is also considered difficult to predict, generally identified only minutes before it occurs. Therefore, Civil Defense reinforces the importance of the population remaining attentive to the alerts issued by the agency.
Inmet also highlights that every cold front is associated with a cyclone. However, this system does not always form over the continent and cause a tornado. Generally, this phenomenon has a greater influence on maritime conditions.
