Heat wave in Brazil: find out what it is and its consequences

One heat wave should reach Brazil in all regions this week, according to MetSul Meteorologia. The biggest Expected temperatures will be between 40º C and 45° C.

Although the week is already starting with heat, the forecast is that temperatures will increase from Thursday (21).

There are fifteen states that should be affected by the air mass warm. One of the capitals that will have the highest temperature will be Cuiabá (MT), what can reach 43º C maximum on Thursday (21) and Friday (22), according to forecasts from the National Institute of Meteorology (Inmet).

The condition is a "situation of high danger due to the severity of the expected heat and which will require attention from the authorities". The level of exceptional heat could be harmful to health and life, with a greater risk to the vulnerable population, such as the sick and elderly, warns MetSul.

What is a heat wave?

The heat wave is an atmospheric phenomenon in which temperatures rise abnormally compared to to the maximum temperatures already recorded in the place, says Geography professor Paloma Guitarrara in this article.

A mass of hot air is responsible for causing this increase in temperature. The relative humidity of the air can be changed with this process, explains the educator.
