A tornado occurred in Kaiyuan City, Liaoning Province. Why can tornadoes occur in urban areas?

Tornadoes do not necessarily form in open areas. Even in urban areas with high-rise buildings, once the atmospheric stability is particularly poor, or because of geographical factors, tornadoes may occur. Once there is a tornado in the city, the level will definitely not be particularly small. In this case, you should immediately hide in the building, and be sure to close all the doors and windows at home, so that the atmospheric pressure inside the house is completely isolated from the atmospheric pressure outside the house, and the loss is minimized.

A tornado with the magnitude of 1 1 occurred in the United States. This tornado happened in the middle of the city. If I remember correctly, the tornado happened in Detroit, which was in a period of rapid development, dense population and high-rise buildings. The tornado appeared without warning and quickly formed in ten minutes, causing great damage to Detroit.

In later research, scientists found that the atmospheric pressure on the day of the tornado was very unstable, and people were frightened by the undulating road map. It is impossible to predict this situation in advance, and this kind of problem often occurs only in a few seconds. According to the current technology, it takes at least a period of scientific research to predict tornadoes.

After the tornado, our first task is to avoid it and never run along a straight line. In the absence of transportation, you must find a shelter, so as to avoid the damage caused by the tornado, because every place where the tornado passes will lift some debris nearby to the sky and then fall heavily to the ground. In this process, in order to prevent the sundries from falling on us, we must hide in the building.

Tornadoes move very fast and have a particularly large radius. In this case, people's legs can't run away from the tornado. If there is any means of transportation, they should leave this place quickly. If there is no transportation and no suitable shelter at present, you must run sideways to get rid of the tornado.
