What is a hurricane: briefly about the terrible phenomenon of nature

What is a hurricane? How does it differ from a storm, a typhoon, a strong wind, a tornado or a tornado? Why do hurricanes have such destructive power? Is it possible to predict the birth of a hurricane, to avoid a collision with it? Let's try to understand.

What is a hurricane?

Hurricane is a very strong wind, the speed of which exceeds 120 kilometers per hour. If it reaches 180 kilometers, then the hurricane is considered very strong. It can be tropical and has nothing to do with the tropics. The first are formed, as the name implies, over the tropics. Tropical cyclones that arise over the Pacific Ocean are often called typhoons. They are accompanied by a low pressure area. Hurricanes appearing over the Atlantic are often called cyclones. Non-tropical hurricanes can occur elsewhere on the planet, but the reason for their occurrence is the same: the difference in temperature and atmospheric pressure in different layers of the atmosphere. The most dangerous are hurricanes, which form near the coast. They, sweeping at a furious speed, are able to sweep entire cities out of their way. What is a hurricane? This is a terrible danger that a person has not yet learned to prevent. These are hundreds of dead, a ruined economy, and destroyed cities.

Hurricane Katrina

It happened in August 2005 and remains so far one of the Most destructive. It began to form in the Bahamas and in a day's time reached such strength that it got the fifth, the highest category, not yet reaching America. This means that the wind speed exceeded 280 kilometers per hour. Not all technical devices can move around the ground at this speed. Having reached the United States, "Katrina" dared New Orleans, destroyed 1836 Americans. More than 700 of them lived in New Orleans. In the area of the hurricane there were 4 staffs at once. They announced an emergency, evacuated the population, but could not prevent the destruction: people do not yet have such skills. The damage Katrina inflicted on the US amounted to $ 125 billion. What is a hurricane? This is, as the experience of New Orleans has shown, the rampant crime. On the ruined city, looters freely moved, who plundered shops and miraculously survived buildings. Several shellings of the city hospital were registered. Truly a hurricane is a terrible test for people.

How does a hurricane form?

The photo above shows how warm air and cold masses are encountered. If the temperature of the water in the tropics exceeds 27 degrees, then the probability of a hurricane is increased many times. Faced with each other, air masses of different temperatures form a low pressure region, which becomes the birth point of the hurricane. The speed of its development and movement can be affected by the rotation of the Earth. Observing from the outside of the weather, scientists have learned to predict where exactly there is a threat of a hurricane. But they can not calculate its strength or the exact path of the movement. It is good, if the governments manage to evacuate the population of those places that can be destroyed by uncontrollable elements. And if not?
