Brazil

Twenty-five of Brazil's 26 states have recorded at least one tornado since 1970, the only one without confirmation being the state of Acre. Even the Federal District has experienced tornado episodes, but most of them were landspouts. This is due to the tropical, semi-humid climate present throughout the country, but the southern states, the interior of São Paulo state in the Southeast, and southern Mato Grosso do Sul in the Center-West, are the most recorded, accounting for 95% of the country's tornadoes. This is because they are part of the "Pasillo de los tornados", a region of South America prone to tornadoes due to the meeting of warm, humid air masses from the Amazon rainforest, Gran Chaco, and the Atlantic Ocean, which meet cold, dry air masses from Patagonia and Antarctica, in addition to the hot, dry winds from the Andes mountain range. These areas are also influenced by severe convective storms from the Río de la Plata basin. A Harvard study revealed that the frequency of tornadoes in this alley is not even higher due to the ruggedness of the Amazon rainforest, which reduces vorticity near the ground. Although this region experiences a high number of severe storms throughout the year, this limitation significantly reduces the chances of tornado formation. Possibly, without this obstacle, the region could have a frequency equal to or even greater than that of North America.
