And what are hurricanes?

Probably, we all have heard more than once that somewhere in our country or outside it there was a severe hurricane and delivered a lot of troubles, breaking power lines, uprooting century-old trees, knocking roofs off buildings and knocking down billboards.

Have you ever thought about what hurricanes are, how they are formed and what strength they have?

Let's try to figure it out together.

Section 1. What are hurricanes? general information

A typhoon or a hurricane is the strongest wind that can blow for a long time at a speed exceeding 32 m / sec.

It is a vortex, whose characteristic feature can be considered a lower atmospheric pressure, observed inside - in the so-called "core".

By the way, in practice hurricanes are usually called tropical cyclones, peculiar mainly to South and North America.

It is believed that the usual storm for us goes into a hurricane in the event that the wind speed exceeds 120 km / h. And with a strong typhoon, it sometimes reaches 180 km / h.

One can not but note the fact that the most powerful and destructive winds, as a rule, occur on the coast. They often not only sweep away everything in their path, but also form huge waves that fall on the shore.

In principle, this type of precipitation is formed exclusively in tropical latitudes and only above the ocean surface. This automatically means that the deeper in the territory of the mainland we are, the less our chances of becoming hostage to the elements.

It is difficult to single out any one reason for the formation of such a strong wind. Firstly, this is the difference in atmospheric pressure or temperature of different layers of the atmosphere, and secondly, the rotation force of the planet also plays a significant role in what is happening.

However, it should be noted that neither a typhoon nor a hurricane is formed until the water surface warms up to at least 27 ° C.

Section 2. What are hurricanes? The most destructive hurricane in US history
By the way, in the USA it is customary for hurricanes to give purely female names. And this is done in alphabetical order, starting, of course, with the letter "A". Every year the situation repeats, which means that after spending some time, an inquisitive person can find out what a hurricane has hit the country at any given time.

In history, Katrina is considered one of the most destructive. According to the special Saffir-Simpson scale, this hurricane was awarded the highest 5 category. The element took place at the very end of August 2005. According to the calculations, the heaviest damage was inflicted on the American state of Louisiana, namely, its capital, New Orleans. In almost a few hours, 80% of the city was under water, almost 2,000 people were killed, and the economic damage as a whole amounted to 125 billion dollars.

Section 3. What are hurricanes? Can they be in our latitudes ?

Based on the definition, on the mainland, hurricanes are rare. And in this there is, perhaps, nothing surprising, tk. Formed on the surface of the ocean, this element, as a rule, in most cases, collapses on the coast.

What we can observe, say, in Moscow, St. Petersburg or Kiev, most likely is called a "squall" or "a wind storm," which, fortunately, is far from the present hurricane.

This is more real for the coastal zones of the Black Sea. For example, the April hurricane in the Crimea managed to cause trouble for local residents, as well as for numerous vacationers. The wind at a speed of 30 meters per second managed to break down trees, destroy the fences of the Shevchenko Park in Yalta, tear down and destroy the billboards.

Fortunately, there were no human casualties.
