Winter starts at 11:58 am this Wednesday (21st) in Brazil and runs until 3:50 am on September 23rd. This year, the coldest season of the year will have milder temperatures because of the influence of El Niño. El Niño consists of the warming of the Pacific waters in the Equator region, with changes in the circulation of winds and the distribution of rainfall across the planet. Therefore, this winter, the forecast is for below average rainfall in the North and Northeast regions, and more volumes in the Southeast and South. “Generally, the impact that El Niño causes in Brazil is the reduction of rainfall in the North and Northeast regions, while in the South and Southeast regions there is an increase in rainfall. In the case of temperature, there is an upward trend in much of the country and this increase may increase the risk of fires in central Brazil. This way, we will have a less rigorous winter due to El Niño”, explains meteorologist Danielle Ferreira, from the National Institute of Meteorology (Inmet). But the meteorologist does not rule out the entry of cold air masses and the formation of frost in higher altitude areas in the South and Southeast regions. According to the forecast released by Inmet, the drop in temperature could cause cold days in the states of Mato Grosso, Rondônia, Acre and in the south of Amazonas. Arte/Agência Brasil El Niño The arrival of El Niño was confirmed this month by the Climate Prediction Center of the Oceanic and Atmospheric Administration of the United States (NOAA). The tendency is for the phenomenon to act during the winter. El Niño is characterized by abnormal and persistent heating of the surface of the Pacific Ocean in the region of the Equator, which can extend from the coast of South America to the middle of the Equatorial Pacific. During the influence of the phenomenon, the water temperature rises by 0.5º C between six months and two years. One of the effects it could cause in Brazil is to increase the risk of drought in the North and Northeast and of large volumes of rain in the South. Learn more about El Niño
