Sweltering heat acts like a pot lid trapping heat, meteorologist tells CNN

MetSul meteorologist, Estael Sias, told CNN this Monday (18), that the suffocating heat that hits Brazil this week acts like a pan lid.

The forecast, according to Estael, is that, until the middle of next week, the country will go through a prolonged period of dry air that intensifies as the days go by.

“[O calor] creates the mechanism of feedback, in which dry air heats the atmosphere more and the atmosphere ends up leaving the air drier. It forms a real heat dome. We have to imagine it as if it were a pan lid holding this heat on the surface and each day that passes keeping this air dry”, explained the meteorologist.

The forecast indicates that a suffocating heat wave will hit the Southeast region this week, bringing high temperatures and firm weather, according to Climatempo.

It shouldn’t rain in Vitória, Belo Horizonte, Rio de Janeiro, and most of Minas Gerais. In the Triângulo Mineiro, in the interior and in the metropolitan region of São Paulo, lots of sun and high temperatures, but with rain showers in the afternoon. In the capital of São Paulo, thermometers must exceed 32 °C.

The suffocating heat bubble is expected to hit, above all, the states of Goiás, Mato Grosso and Mato Grosso do Sul, as well as Paraguay.

“We believe that this is the most critical region in terms of temperature marks and with potential for records, perhaps even breaking that record from 2020, which we had 44.7 °C in Nova Maringá (MT)”, he stated. Estael.

The expectation, according to the meteorologist, is that the Southeast and Central-West regions will record higher temperatures than those that will be seen during the summer.

“The summer is rainy in the Southeast and Central West, so it is unlikely that we will have higher temperature marks in this region in the summer than now,” he declared.
