According to the main measurements of meteorological services, such as that of the National Institute of Meteorology (Imme), foresee that the temperature will achieve extreme figures and reach the 40 ° C. for next Monday, with up to 80% moisture, and with Thermal sensations Intolerable almost 62.7 ° C..
“In fact, It is not fully known why it is so hot in Rio de Janeiro. It is a complex sum of factors that make us have terrible heat, “he said Wallace MenezesProfessor of Meteorology at the Federal University of Rio de Janeiro (UFRJ).
Extreme heat in Rio de Janeiro: main causes
Menezes He maintains that river is a “Urban Heat Island“, product of the greenhouse formed by the asphalt, the emissions of vehicles and the industries, the buildings and the influence of certain Geographical aspectslike reliefs.
One of the biggest problems is High pressureor anticyclone, what Heat the air by compression. That system pushes and compresses the air down and makes it heat and dry in the process, preventing cloud formation and causing dry air to heat up to a much higher speed, product of solar radiation.
What symptoms the body presents and what measures to take in front of the heat
In the famous Carioca capital are expected daily temperatures of more than 36 ° C.measures at the level of the shadow, and a Thermal sensation of more than 50 ° C.. The combination of several days of intense heats, produces that the impact is greater because objects and materials begin to reheat and lift one Extreme temperatureproducing more heat.
Gonçalves fableProfessor of Biometeorology at the University of San Pablo (USP), said the Heat tolerance It depends on one individual to another, but that the risk, regardless of the age and good health of the person, begins when the air temperature exceeds the human bodysome 36.5 ° C..
The forecast of High moisture levels In Rio it is one of the factors that amplifies the Thermal discomfortsince sweat does not evaporate and fails to take the heat that the Body tries to expel. In a little encouraging panorama, the Meteorological services They are not planned in the forecast that falls rain to help reduce the thermometer.
