Throughout its existence, mankind has ever faced with such natural phenomena against which is not able to resist.Although the current level of technological progress, humanity can not afford to control the tornado, typhoon, tornado.The characteristics of these elements are shown below.
One of the natural hazards considered a tornado.He recalls a storm cloud that descended to the ground for a kind of "dance".Its scope is generally up to 400 m, rarely can reach 3000 meters. For many, a mystery, the difference between a tornado tornado.That we are to find out.

Causes tornado
Mankind has not yet been able to understand how tornadoes are formed and tornadoes.Their appearance is associated with the process, when the wet warm air is very close to the cold dry.However, their contact should take place over the cold land or water.Warm air is between low temperatures.
Due to the fact that the process of formation of a tornado is a kind of chain reaction, is a destructive natural phenomenon often compared to the atomic bomb.
Because of the interaction of cold and warm currents formed trunk, which cools and descends.Behind him down and discharge area that draws in everything in its path.
natural hazards
All tornado danger lies in its trunk.Depending on the size of their own, it is able to draw into themselves and raise an enormous height of any items.These include humans.Dissolved in the atmosphere, it falls down and ceases all turned over the earth.
If the vortex is unable to drag an object, it breaks it apart.For example, a house standing in its way, probably in ruins, and its fragments will scatter for tens of kilometers.

Classification Fujita Scale
the question that is stronger - a tornado or a tornado, the answer can not be, because it is one and the same phenomenon.There are many classifications of its power, but most adhere to the Fujita Scale.
| Tornadoes, typhoons, tornadoes: characteristics | ||
| code | Wind speed, km / h | Feature |
|
0 | 116 | applied relatively little damage in the form of broken branches and worn-out trees.In many countries, it called the storm wind |
| 1 | 180 | phenomenon able to rip roofs off houses, moving cars. |
| 2 | 253 | Element pulls trees up by the roots. |
| 3 | 332 | clot is able to overturn the train, raise above the ground car. |
| 4 | 418 | Everything is easier car flying in the air, even as the unfortified should be built. |
| 5 | 512 | Element is able to lift into the air almost everything easily tear off the ground pavement. |
| 6-12 | over 512 | exists only in theory, because the wind can reach the speed of sound. |
Interesting facts
So, we've already figured out what to say about the difference between a tornado tornado is not quite true.Such natural phenomena occur around the world, bringing death and chaos.However, there are cases that can be attributed to the curious.

- In 1940, in the village of Meshchery with thunderstorm rain fell, consisting, in addition to water, of old coins made of silver under Ivan the Terrible.To explain such a miracle is possible that exhausted their energy tornado gives all that sucked in yourself.Maybe he took the treasure, buried not too deep, and after going a certain distance, began to weaken, and gave it to rain upon the earth.
- In 1923, Tennessee element destroyed the walls, the ceiling and the roof of a residential house and took them up.At the same time he remained seated at the table the family who lived in it.All of them have got a fright.

- stay away from windows;
