Chinese call this natural phenomenon "iron ring of winds", but South Americans and Europeans - a typhoon.The air in this case is not an intangible and fluid, because it is already quite solid matter, striking out like a military projectiles!So, in this article we will learn what a typhoon and how it is formed.
eyewitness
Every man who had the imprudence unsuccessful dive into the water by jumping from a great height, knows that even such a liquid substance, like water, can be so solid that causes significant pain body.That typhoon works on the same principle: the air during this tropical cyclone becomes firm like a wall.
What is a typhoon?In the chronicles describing cases of collision of people with these tropical cyclones, there is a story that best characterizes it.An experienced master mariner described this element with the following words: "Typhoon - it is not the wind, it is a wall.It is made of iron. "This is understandable: the wind blowing at a speed of 200 km / h, will be 4 times more powerful air flow, the speed of which - 100 km / h.Why is that?All because of the energy of the moving mass, increases in proportion to the square of its speed.
Many people do not know firsthand what a typhoon.Eyewitnesses describe the horror atmosphere prevailing inside the cyclone.According to them, around the air becomes completely invisible and extends above the ground kind of braid."It's not the storm, it is - a real national disaster!" - Notice the surviving witnesses of violence of a natural disaster.According to them, the powerful "iron" wind uprooted huge trees not only, but also grass.
What is a typhoon?Determination
Translated from the Chinese "Typhoon" - a "strong wind" and in Greek - "Typhon" (mystical monster embodying wind, hurricanes and storms).This element - a type of tropical cyclone, typical of the north-west Pacific.The greatest decrease in air pressure at the surface is observed in the center of the typhoon.
Where they occur, these cyclones?
According to reports seismologists and meteorologists zone most active of these tropical cyclones, which accounts Unfortunately, one third of the total number of various elements on the planet, located between the coast of East Asia (in the West), the equator (in the south) andline change the date (in the east).Seismologists calculated that most of all typhoons formed is from May to November.Nevertheless, in recent years, the disaster occurs erratically, and regardless of the season.
Scientists recall that was particularly devastating typhoon season, which took place in 1991.Then, off the coast of Japan rioted several cyclones.This element from time to time directly affects the borders of our country.For example, to the coast of the Far East typhoons casts after their main blow was adopted by Japan, Korea and the Ryukyu Islands.At risk are the Kuril Islands, Kamchatka, Sakhalin and Primorye Territory.
rise to elements
So above, we learned that a typhoon (definition for kids - big wind swirls), now let's look at how it is born.The basis for the emergence of a tropical cyclone is quite heavy seas.Fuel to the fire adds a concomitant loss of a large amount of precipitation.It is that time is characterized by the change of the monsoon in the eastern and southern seas of Asia (from Arabia to Japan).
It should be noted that any wind coming to the Earth from space, in particular due to increased solar activity.While some of them are people favor (cool, moisture) other sowing catastrophic failure (storms, tornadoes, tornadoes, hurricanes).According to most meteorologists, favorable conditions for the emergence of a tropical typhoon edge occurs during heating of the surface sea water to a temperature of 30 degrees Celsius.
As emerging tropical cyclone?
What is a typhoon in terms of its origin?This, of course, is gradually developing hurricane.Yes, you heard right, it is a hurricane!Upon heating the water surface is increased evaporation, which in turn, absorbs thermal energy.At this time, warm air comes into contact with the upper cool air masses in the atmosphere reigning.All this provokes clouds turning into rain.Precipitation, in turn, is forced to give a large amount of heat energy to the surrounding atmosphere.
All these atmospheric phenomena lead to a strong thrust up and absorption of new masses of moist air from the water surface.When the above cycle is repeated, the intensity increases by several times, which leads to a kind of giant air pump.This is a powerful mechanism of a hurricane.Joined together two elements - wind and water.At this time they acquire the terrible and destructive force.
Typhoon - is nedouragan?
Scientists do not quite understand what the typhoon.For children, it is characterized by a strong wind swirls / hurricane.But for scientists to determine the boundary between the two cyclones is currently not possible.Why is that?The fact that the meteorologists still do not understand the conditions under which hurricanes occur in the Pacific, and it is precisely Pacific cyclone is called a typhoon.
Typically, this element is carried by a narrow strip of land and has a truly destructive force.Tropical Cyclone kills tens and hundreds of lives, not to mention huge material losses.Typhoons jokingly called nedouraganami.Of course, something in common they have: in the first, as second, the mass of air moving around the center, which in turn serves as a center with the lowest atmospheric pressure.
motion path and speed
What typhoon (photos are presented in an article) from the point of view of its trajectory?As we have seen above, this is a chaotic cyclone.Note that its trajectory never been and will not be straight.Speed had also changeable.Sometimes, the typhoon is moving fast, and sometimes it takes only a few miles per hour.Sometimes this nedouragan just stops in the middle.Scientists say this is due to the fact that the cyclone does not reach high altitudes in the atmosphere.
In the sea ...
What is a typhoon in the sea?Seafarers referred to the center of this powerful tropical cyclone "eye."Why is that?The closer to the center, the stronger its winds.This provokes a powerful excitement of sea water.The waves propagate in all directions, changing them more and more.Often at the center of the cyclone wind can suddenly subside, and cloud - scattered, but the sea does not cease.Rarely any vessel may, without prejudice to cross the "eye of the typhoon."Normally sailors trying to avoid the central part.
