Hellish power of tornadoes

Hellish power of tornadoes

For pilots and scientists the National Oceanic and Atmospheric Administration "U.S. flight" eye "(quiet area) violent storm has become a part of their risky work on tracking tropical storms. But the 15 September 1989 the share of the crew of NOAA 42, flying in from hurricane Hugo Antshskih Island to Charleston (South Carolina), has fallen more than they had expected when I took the course of his plane "Lockheed Orion" directly to "Oka" giant storm .

Once NOAA 42 pierced the wall "eye" just a few hundred feet from the calm center of the storm, as the air forces captured the violent, threatening to break it into pieces. One of the four engines failed and courageous "Orion" fell. He was able to correct and return to the "eye", when the sea surface to be only 200 meters.

Later, in analyzing this terrible adventure, the scientists concluded that NOAA 42 zaletel in Baroque atmospheric anomaly - in the tornado, which could not detect, as it to the traditional representations of weather stayed in the wall "eye" Storm Large-scale and the devilish disguise its power .

Tornado in rolling orbits which have the most violent winds on Earth, capable in an instant to destroy everything he touches. During the XVIII and XIX centuries, more than a dozen times in the middle of the day and the sky above New England chernelo and preachers promised close to doomsday. Fortunately, these so-called dark days were not harbingers of divine retribution consequence of the vagaries of the weather.

Weather was not lost its ability to sow fear in the hearts of people. Before the terrifying power of the wind may seem insignificant most destructive weapon of war. Hurricanes sweep through the coastal regions, the estimates are on their way, a tornado korezhat landscape. A sudden gust of wind can knock off the land's largest aircraft.

With all the modern technologies are equally dependent on the mercy of a furious wind, like their distant ancestors. Weather not only a little predictable, but also possesses inexhaustible reserve of tricks and surprises.

Vehemently tornadoes so suddenly and immensely that survivors can rarely remember the details of the incident. However, May 3, 1943 a retired army captain Roy C. Hall went with his family from the "eye" tornadoes and gave a clear description of the vortex that devastated his home in McKinney, Texas, about 50 miles north of Dallas.

As soon as the storm began, Hall closed the wife and children in the bedroom. And then the outer wall of the room with a terrible roar tumble into the interior. But the worst had yet to go. Shrill shriek of wind suddenly verse. "It was just so - and then wrote the Hall - as if I laid ears on the palms, the sound isolation, apart from an unusually strong shock pulse in the ears and head. That feeling I had never felt ".

And freezing silence in this house shudder highlighted strange blue siyaniem.V the same instant Hall dropped by ten feet, and he was under the debris of the wall so suddenly that did not remember how it fell. He vykarabkalsya from the rubble, pressed to his daughter and waited for four years, when his house, which is not kept on the foundation, claim away.

And then it brought intimidating vision. "Something initially committed sinuosity from top to bottom, and then froze in complete immobility, apart from a weak pulsation top down - he wrote later, Hall. - It was a curved line request concavity to me, the bottom outline located almost horizontally ...

It was the lower end of a tornado. At this point, we came in the tornado! "Hall looked up. What he saw looked like opaque, with a smooth surface of the wall thickness of about four meters, the surrounding columnar cavity. "It resembled the inside of enamel riser, - recalls Hall.

- It extends upward for more than three hundred meters, a little shake and slowly dish in the south east. At the bottom, the bottom appeared to circle in front of me, was a crater about 50 meters across. Above it has expanded and, apparently, was partially filled with a cloud of bright, flickering, as the fluorescent lamp ".

Rotating chute swung and Hall saw that the entire convoy was as if drawn from a variety of huge rings, each of which move independently of the others, and caused a wave runs from top to bottom. When the crest of each wave reached the bottom peak of the crater make sounds resembling click whip.

Hall watched in horror as the peak of tornado, referring to a neighboring house, destroyed it. According to Hall, "if the house is dissolved, the different parts of his claim to left, like a spark of emery circle".

Soon the tornado continued its journey to the south east. Family Hall withdrew from changes almost intact. At the cost of losing the house they received from the "eye" huge storm a rare opportunity to look at the brutal violence of nature in the midst of his proyavleniy.Tornado famous not only brutality, but also comicality.

Cradling winds speed reaching 200 miles per hour, can be stuck a straw in the trunk of the tree and make wood chips pierced sheet steel. At the same time, strong internal vortices, hidden in the tornado, probably responsible for the fact that some items are subject to destruction, while others remain unharmed. A bottom-up air flows can serve as a pillow: it happened that people flew in the air, only to then sit quietly on the ground amidst fierce storms.

Here are some of the amazing incidents in the life of a tornado. Tornado destroyed the town in 1974, Xenia, Ohio, completely destroyed the house of a farmer, with all that it was, but spared two fragile object: a mirror and a box of Christmas decorations.

April 11, 1965 tornado shoot for a large part of the Middle Western United States. One of them in Cleveland, Ohio, has raised a teenager out of bed, made to the window and landed, unharmed, on the other side of the street. And he was never muffled in a blanket. Another tornado in Dunlop, Indiana, drew eight distorts the baby from the house and put it on the ground nearby.

In Grand Repidz, Michigan, a man moved with its own verandah on the chest schepok - all that remains of his house soseda.10 June 1958 in El Dorado, Kansas, a woman vyshvyrnulo out of the window. She successfully landed 20 meters from the house. Next to her record fell to record the song "bad weather".

May 25, 1955 in Yudolle, Kansas, a powerful gust of wind Fred Daya vydernulo of shoes and throw on a tree, where he peresidel storm. Not far from the husband and wife came out of giving them the security of a bedroom, and found that all the other rooms at home claimed.

Jun 23, 1944 tornado quickly suck dry the West Fork River in West Virginii.Vskore after March 18, 1925 through Illinois shoot tornadoes, the land fell page of the magazine "Litereri Digest". It was a photo and description of tornadoes in 1917.
