Understand how the Yakecan cyclone was formed, which hit southern Brazil

The southern region of Brazil was affected throughout the week by the arrival of the subtropical cyclone Yakecan. The storm has already lost strength, but the Civil Defense remains with alerts for the coastal regions of Rio Grande do Sul, Santa Catarina and Paraná.

Cyclones are systems of low atmospheric pressure in which the winds move so that there is convergence from their center. The term is a generic name used to describe the phenomenon that forms in these areas.

Usually, these cyclones arise mainly over the oceans, generally in tropical regions (between the tropics of Cancer and Capricorn), they can last several days and travel long distances, becoming, in some cases, very intense.

In a press conference on Monday (16), Marcia Seabra, Meteorology coordinator at the National Institute of Meteorology (Inmet), said that the difference with this storm is that it will move towards the continent and arrive on the coast of Rio Grande do Sul. .

Every cold front, like the one that hits Brazil, has an extratropical cyclone associated with it. In the case of the Yakecan, in particular, it detached itself from the front that accompanied it and changed its category — to subtropical, because it was in the extreme south of Rio Grande do Sul, she said.

Yakecan rating

The name Yakecan means “sound of the sky” in the Tupi-Guarani language, and was named following the Maritime Authority’s Norm for Maritime Meteorology (Normam) – which names atypical cyclones (subtropical and tropical).

According to Miguel Ivan, director of the National Institute of Meteorology (Inmet), “when the Navy names a cyclone it is because it has relevance and can impact people’s lives”, he said.

According to Inmet, the passage of a cyclone is not a reason to panic, but it is necessary to be careful. “The Yakecan is a situation of care and attention: 100 km/h of intensity is a lot. Wind at 100 km/h is very strong”, said Ivan.

Also according to the representative of the institute, winds with speeds of up to 120 km/h are classified as a tropical storm. Above that, they are classified as a hurricane.

According to Climatempo, the wind driven by the storm reached 107.6 km/h in the Siderópolis region, in southern Santa Catarina – the highest intensity ever recorded by the Santa Catarina Environmental Resources and Hydrometeorology Information Center (Ciram).

Storm starts to lose strength

Although the storm is already losing strength, the cyclone continues to drive a drop in temperatures across the country. Weather warnings involve risk of heavy rains, cold waves, gales and low temperatures.

On Tuesday, the 17th, a fisherman died in Porto Alegre (RS) after the boat he was in capsized after the wind.
