– a strong atmospheric vortex over land, characterized by exceptionally high repeatability.
Tornadoes occur quite often, but to foresee where exactly it will occur next time, it is impossible, and so the tornado has to “chase”. The mobile laboratories used in such chases are too fragile and destroyed before they manage to reach the center of the tornado and begin to study it.
It was not yet possible to obtain a tornado in a laboratory under controlled conditions: an experimental installation measuring hundreds of meters would be required for this.
The tornado is still an obscure atmospheric phenomenon, surrounded by many myths and misconceptions.


Usually, when a tornado comes, there is a time to hide from adversity.

In fact, it is not always possible to guess that a real hurricane has come, since it can start with hail or heavy rain. In the wooded area, in the mountains or in the city, very often danger is seen when it is already inevitable. It is also necessary to know that some tornadoes do not have the appearance of a typical column that descends from the clouds. The arrival of the tornado is accompanied by strong winds, carrying the fragments of everything that they found on their way.

My car can go much faster than a tornado.

In fact, the average speed of the tornado is 40-65 km / h, and some are moving at an even faster rate. Even if your car can move faster than a tornado, this does not mean that you have to continue your journey, because the tornado moves in a variety of directions. If you are on the road and see a tornado moving in your direction, turn off the path of its movement and take a refuge.

If there is no other way to take refuge, then the car will become a more reliable refuge than a trailer or a country house.

In fact, this is not always the case. This topic is hotly debated in North America. If there is time, you can jump into the car and take cover there. In the case of a tornado of low power, the car will provide reliable shelter from objects carried by the flow of wind or rolling on the ground. It is best to fasten your head and bend your head as low as possible. However, do not forget that a stronger tornado can destroy the machines that are on its way.


About the tornadoes you can learn enough in advance to have time to warn the population, thanks to Doppler radar.

Doppler radars recognize the formation of precipitation and wind accompanying a storm, and allow meteorologists to detect signs of an approaching tornado. But the tornado approach can be affirmed with certainty only when the tornado is in sight. If meteorological services warn of the approach of a thunderstorm, then there is a possibility of a tornado.

Settlements located near rivers, lakes and mountains are well protected from the appearance of a tornado.

Actually, there is no such place, which would be completely protected from the tornado. They can cross water surfaces and even form above water. Thunderstorms tend to become less intense over large lakes, but they can also grow into tornadoes when reaching the shore. It should be noted that in most cases tornadoes do not occur near water streams.

A sudden pressure surge accompanying a tornado can blow up a building. Hence, you should open all windows to balance the internal and external air pressure.

Most of the material damage is caused by the wind and objects that it carries. Because of this, it is necessary to avoid open windows and hide in secure places, away from doors, windows and outside walls. With a tornado, every second counts and you need to hurry to go to the shelter. It is necessary to close tightly and strengthen the windows so that rain, hail and wind can not get into the room and cause damage.

Tornadoes are more likely to occur in the area where trailers and mobile homes are located.

Mobile homes are not able to attract a tornado, but they are the most vulnerable due to their design.

When a tornado needs to hide in the south-west side of the basement.

This assertion is not proved. It proceeds from the belief that tornadoes usually come from the southwest, and that objects carried by the wind will fall to the opposite side of the basement. But in fact, a tornado can appear on either side and the objects that it carries can fall anywhere. In general, tables, stairs, mattresses and other objects with sufficient weight are well protected against tornadoes and objects carried by them.


Highways are a good shelter from a tornado.

This statement appeared after the show of one series in the early 1990s. In fact, freeways are able to attract a tornado and are therefore a particularly dangerous place. In recent years, many people have been seriously injured or killed trying to hide from the tornadoes on motorways. On the contrary, it is necessary to go to a pit or a deep hollow, where there is no risk of automobile collisions. However, be careful not to drown and be flooded with water.

The bigger the tornado, the more destructive it is.

The appearance and size of the tornado can be deceiving: apparently innocuous natural phenomena can be more destructive than others, have a more intense wind force, and more impressive externally, on the contrary. The Fujita scale, which serves to determine the severity of a tornado, is based not on their size, but on the destructive force.

Tornadoes never hit big cities.

In fact, tornadoes are not afraid of cities: for example, Winnipeg was struck by a tornado 12 times, of which one person perished once. Regina was struck 18 times, and after the tornado in 1912, 28 deaths were recorded. In Edmonton, 18 tornadoes visited, one of which in 1987 was the most deadly (27 people were killed).

If the storm is heading east, then the threat is over.

The truth is that most thunderstorms go from west to east, but sometimes they can change their direction to the opposite. The tornado that hit Nipava (Manitoba) in 2000 moved from east to west for 10 kilometers before it subsided.
