Strong typhoon, tornado, high temperature and high humidity city

In the tornado corridor in the midwest of the United States, more than 1, tornadoes break out every year. There, tornadoes with a speed of 5 km/h go crazy. As long as you walk in here, you are likely to die because of deadly weapons thrown by tornadoes, heavy hail from the sky or extremely hot lightning. Therefore, it is best to travel without going to the tornado corridor, which may be the most dangerous place in the world.

The tornado corridor extends from the Rocky Mountains to the Appalachian Mountains. On average, there will be 1 tornadoes here every year, and the wind speed will reach 5 km/h, and all the farmland, houses, people and livestock passing by will be destroyed. The Interstate 44 between Oklahoma City and Tulsa is called the "I-44 Tornado Corridor", where more than 1 million residents are used to the annual tornado season. Every spring, when the dry cold air from the Rocky Mountains passes through this lowland plain and meets the humid hot air from the Gulf Coast, tornadoes arrive as scheduled.

Since 189, more than 12 tornadoes have hit Oklahoma City and its surrounding areas. On May 3, 1999, a tornado swept through the area around Oklahoma City, which razed 1,7 homes and damaged 6,5 buildings. Most areas along the same road in the northeast of Oklahoma City are also often hit by tornadoes. In Tulsa, a small town with a population of 59,, there were 69 tornadoes between 195 and 26. In addition, Tulsa is built on the Arkansas River, which is a plain alluvial by a series of streams, and it is also vulnerable to floods in the bad weather of heavy rain. Three large-scale floods in 1974, 1976 and 1984 caused hundreds of thousands of dollars in losses.

in December, 21, American scientists discovered that many places in the southern States of the United States may be more prone to tornadoes than Kansas. By counting the incidence of tornadoes per square kilometer in 48 states in the United States except Alaska from 195 to 27, P. Grady Dixon, a geoscientist at Mississippi State University, and his colleagues determined that in some areas of a large area in south-central Mississippi and central Arkansas (areas indicated by orange and crimson in the figure), at least one tornado passes through 25 miles every year. This ratio is similar to what happens in tornado hot spots on the great plains. Compared with many places that are traditionally considered to be located in the center of the tornado corridor, some places in Smith County, Mississippi, which is the most severely affected area in American history, have a higher probability of tornadoes by about 35%. The research team pointed out that expanding the tornado hazard map including these areas will raise public awareness and increase efforts to reduce the losses caused by tornadoes.
