Many states in the central United States suffered at least 30 tornadoes on the night of the 10th, and Kentucky was the most seriously affected, and the number of victims may exceed 100. US President Joseph Biden said on the 11th that this may be one of the largest tornadoes in US history. The United States is known as the "home of tornadoes" and produces thousands of tornadoes every year. However, according to weather forecasters, tornadoes appear unusually during the cooler months. Victor Gensini, a professor of geography and atmospheric sciences at Northern Illinois University, said the unusually high temperatures and humidity created the environment for extreme weather events at this time of year.
