The Canadian tornado hit the fruit stall accurately. Do tornadoes often appear in Canada?

Yes, there are often tornadoes in Canada. In addition, Ilia, southern Manitoba, camping in Malu County and so on are all vulnerable to tornadoes. Recently, a video filmed a couple in Haines Zhangkeshen, Canada, buying fruit at a fruit stand and suddenly encountered a tornado. The strong wind swept up a lot of sand on the road and blew away the fruit and cash on the booth. The stall owner said it was too helpless. Some netizens joked that when a tornado rolls these fruits into the sky, it will inevitably drop the fruits in other places.

First of all, it is extremely destructive.

A tornado in Canada will inevitably cause immeasurable losses to the affected areas. The damage to buildings caused by tornadoes is quite serious. Under the attack of tornado, the roof of the house will be blown up. Once the roof is swept away, the rest of the house will disintegrate and disperse with the wind. If humans are attacked, they will be killed or injured. The wind in the center of the tornado is very strong. Once the house is attacked, it will be completely destroyed in an instant. At present, buildings in many cities often have fragile structures such as glass curtain walls and iron roofs. Once encountering tornadoes, they will cause fatal injuries, falling from the sky and hitting pedestrians.

Second, signs of tornadoes.

One sign of a tornado is that before it appeared, the sky was usually dark, thundering and stormy, with green clouds and roaring sounds. There are two general meteorological conditions for tornadoes: first, there is quite warm and humid air in the lower atmosphere. Before the tornado appeared, the weather was particularly hot and humid, and people felt heavy and depressed. Second, the middle air in the atmosphere is dry and cold, forming a powerful potentially unstable air. With these two conditions, when weather systems such as low pressure, front and typhoon approach, a large amount of unstable energy in the air can be triggered to be released continuously, forming a tornado.

Third, avoid tornadoes.

The best place to avoid tornadoes is underground, so choose basement or windbreak cellar as shelter at home. Don't wait until you see the strong wind, it's too late. Don't go to some houses built of wood and iron or damaged buildings to prevent the buildings from collapsing and the roofs from being blown away by the wind, which will be even more dangerous at that time. If you drive on the road, pull over immediately, fasten your seat belt and keep the engine running. At the same time, keep your head under the window and cover your head with your hands and blankets.

When a tornado comes, it is best to choose a room in the north or northeast. The room facing east and west is more dangerous, and the room facing east tornado is safer because there are no weak and fragile links such as doors and windows. If there is nowhere to escape, close the door and window of the room facing the tornado and open another window, so that even if the tornado blows into the room, it will quickly go out from the other window, which can reduce the injury. If you are outside, don't coincide with the route from the tornado, and choose to run at right angles to it. If it is an empty wilderness, choose a low-lying place to squat and hold your head. If you are driving, you should leave the highland or bridge deck, drive to a flat and low-lying place, and stop to avoid it. If you have time, people should get off, because tornadoes can easily overturn the car.
