The second week will see an extratropical cyclone in the southern region, bringing colder days and more rain.
The cold weather and rainy It should continue into the second half of November in most of Brazil. Due to the influence of factors such as la niña Temperatures are not expected to rise as much as expected just before arrival (due to the cooling of surface waters in the Pacific Ocean, which changes the climate around the world) and the formation of extratropical cyclones. summer.
Temperatures have been rising again in most areas in recent days. southern region and southeastbut it should fall again soon. In the south, an extratropical cyclone is expected to form next Sunday, the 16th, with heavy rain and severe weather expected during that time. rio grande do sul and santa catarina.
Marcelo Cerci, Operations and Modeling Coordinator at the National Natural Hazards Monitoring and Warning Center (Semaden), emphasizes that predictability for a given weather system for more than two weeks is difficult to achieve.
“Weather models may even indicate that three star systems will form (during the remainder of this month). However, reality is likely to be very different from predictions as they are unreliable,” he points out.
Cerci emphasizes that basically all cold fronts in Brazil are usually somewhere in the tropical cyclone range. atlantic oceanoften happens quickly. “Cyclones are not uncommon, but the opposite is true,” he says.

Another effect of La Niña is increased rain and cloudiness. northeast The heat eases in the second half of the month.
Abnormal weather such as tornadoes, Destroyed the city of Rio Bonito do Iguacuin parana stateit may happen again, but it is difficult to predict in advance. “Weather events of great intensity and magnitude are very complex. Rigorous research is therefore needed to improve predictive tools, with the aim of predicting and mitigating social and economic damage,” Carvalho concludes.
