A historic heat episode will hit Brazil this week with temperatures above 40ºC, including Espírito Santo. The phenomenon will occur mainly in the South, Midwest and Southeast regions of the country, and in some places the thermometers can reach or approach 45ºC.
The alert is from MetSul Meteorologia, which also reports that there will be the possibility of breaking maximum maximum temperature records in some cities and that the marks will be among the highest recorded in decades in some regions.
According to MetSul, the intense heat wave, due to its size and intensity, will recall extreme events of high temperature and dry air that often reach California and Australia.
According to information from Climatempo, the extraordinary increase in temperature will be felt until October 7 in the following states, with different degrees of severity: Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Minas Gerais, Espírito Santo Santo, Mato Grosso do Sul, Mato Grosso, Goiás, Federal District, Rondônia, Acre, Amazonas, Pará, Tocantins, Maranhão, Piauí, Ceará, Pernambuco and Bahia
A large mass of hot, dry air will cover central Brazil for several weeks with extremely high maxima, reaching the highest maximum in Cuiabá since the start of measurements in 1911 at almost 43ºC, MetSul Meteorologia highlights.
It is a giant hot air bubble, a heat dome or “heat dome” in English, in which an area of high pressure at altitude generates sinking (downward) movements in the atmosphere with extreme heat and very dry weather. . The severe drought with low availability of moisture in the soil ends up aggravating the situation and creating a feedback mechanism in which dry weather aggravates heat and heat aggravates dry weather, generating even greater evapotranspiration.
