Well-known US storm chaser plans to come to southern Brazil to watch tornadoes

North American storm chaser and meteorologist Reed Timmer Disclosure/ North American meteorologist Reed Timmer published on social media, on the 9th, that he intends to visit the country. The reason is the tornadoes recorded in Rio Grande do Sul and Paraná. Through the publication, Timmer said that the El Niño phenomenon is boosting the South American Tornado Corridor and that he would come to closely observe with his team, Team Dominator, the climatic event that, according to him, should be recorded again between the end of winter and spring. ?

Understand, in the video below, why RS is among the most favorable regions in the world for this phenomenon to occur. Tornadoes: why RS is among the most favorable regions in the world for the phenomenon Who is Reed Timmer Reed Timmer is an extreme weather meteorologist and storm chaser. He is known for closely monitoring severe storms to record and study the phenomena. To face tornadoes and hurricanes, he uses an armored vehicle adapted to withstand adverse situations. The team also has drones, small aircraft and even rockets. In 2009, Timmer observed a tornado in LaGrange, Wyoming, in the United States, with wind gusts of 155.2 mph, equivalent to 249.8 km/h. All this from inside the phenomenon, using an armored vehicle. Tornado corridor The record of a tornado in the interior of Pedro Osório, in the south of Rio Grande do Sul, on the 6th, marked the second consecutive week with the occurrence of the phenomenon in the state. Before Pedro Osório, municipalities in the Northwest of Rio Grande do Sul had already been hit by a tornado on July 28. The recurrence of tornadoes within a short interval has a geographical explanation. Rio Grande do Sul is part of the so-called tornado corridor of South America. The region is considered the second most favorable on the planet for the formation of these phenomena, behind only the central area of ??the United States. In this strip of the continent, there is a frequent clash between the hot, humid air coming from the Amazon and the cold air masses advancing from the south. When the winds change direction and speed depending on altitude, the storm begins to rotate, forming the rotating column of air that connects the cloud to the ground. "The chance of a tornado occurring in RS increases when you have greater contrast, a hot front, with high instability", says climatologist and professor at the Federal University of Rio Grande do Sul (UFRGS), Francisco Eliseu Aquino. What is a tornado ?? Tornadoes are minor, but very intense, atmospheric phenomena. They generally arise from severe storms in areas with large wind variations. Meteorology can identify when there are favorable conditions for severe storms, but it is not yet possible to accurately indicate the point at which a tornado will form or touch down. ?? A supercell is a storm that has a rotating air current inside the cloud. This type of formation can generate heavy rain, hail, wind and tornadoes. ? The cyclone, in turn, is a much larger system, formed by an area of ??low atmospheric pressure. It can contribute to the formation of severe thunderstorms, but it is not a giant tornado. While a cyclone can be hundreds or even more than a thousand kilometers long, a tornado is usually a few tens or hundreds of meters wide when it touches down. ?Scale: the tornado is smaller and usually hits a narrow range. A storm or cyclone can spread over hundreds of kilometers. ?? Duration: tornadoes usually remain on the ground for a few minutes. A storm can last for hours, while a cyclone can last for several days. ? Intensity: despite being small, the tornado concentrates very strong winds in a limited area. Therefore, it can destroy one house and leave another, located a short distance away, practically intact. What can enhance the formation of the phenomenon In addition to geographic position, global warming and climate phenomena increase the risks. The meteorologist at the Federal University of Santa Maria (UFSM), Maurício Ilha de Oliveira, points out that a warmer environment provides the ideal ingredients for severe storms. The El Niño phenomenon also has an influence. Climatempo meteorologist, César Soares, adds that the higher temperatures of El Niño make storms more frequent in the South, favoring the formation of tornadoes. ? El Niño is a natural climate phenomenon that occurs at irregular intervals, generally every 2 to 7 years. It is characterized by warming greater than or equal to 0.5ºC of the surface waters of the Equatorial Pacific Ocean. This warming alters the circulation of winds and the distribution of heat and humidity around the globe, impacting climate patterns in different parts of the world. Rio Grande do Sul's climate history confirms the trend. The Digital Disaster Atlas points out that, since 1991, Rio Grande do Sul has recorded at least 31 disasters associated with tornadoes. The events directly affected more than 7,600 people and caused around R$68 million in material losses.
