The explanation for this atypical winter is at the south pole. According to meteorologist César Soares, this is because the cold waves were restricted to Rio Grande do Sul.
“We had two strong cold waves that reached the southeast, but the big problem is that throughout this winter we did not have as much presence of the polar air masses because they did not arrive with such power here,” he explains.
“They were more concentrated in southern Brazil, especially in the state of Rio Grande do Sul, and the polar jet could not rise so far to the southeast to favor the transport of these air masses,” said the meteorologist.
