Imaginez être si proche d'une tornade que vous pourriez en voir l'intérieur—et en sortir vivant ! C'est exactement ce qui est arrivé à quelques personnes courageuses (et très chanceuses). Elles ont décrit l'intérieur de la tornade comme un mélange de chaos et de calme, avec des débris tourbillonnant partout et un silence étrange, presque paisible, dans l'œil. Un homme a même dit que cela ressemblait à une "énorme machine à laver de destruction" autour de lui. Par miracle, ils ont réussi à s'échapper avec des blessures mineures, ce qui semble presque impossible étant donné la puissance des tornades. Leur histoire est un rappel de la puissance brute de la nature—et pourquoi il vaut mieux garder ses distances avec les tornades ! 🌪️ Animation créée par Sympa. ---------------------------------------------------------------------------------------- Musique par Epidemic Sound https://www.epidemicsound.com Pour ne rien perdre de Sympa, abonnez-vous!: https://goo.gl/6E4Xna ---------------------------------------------------------------------------------------- Nos réseaux sociaux : Facebook: https://www.facebook.com/sympasympacom/ Instagram: https://www.instagram.com/sympa.officiel/ Stock de fichiers (photos, vidéos et autres): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru ---------------------------------------------------------------------------------------- Si tu en veux encore plus, fais un tour ici: http://sympa-sympa.com

FunTranscript
00:00In June 1928, a certain Mr. Keller almost lost his life in a terrifying natural disaster.
00:07He was outside with his family when he noticed a cloud in the shape of an umbrella that seemed to be approaching them.
00:13He felt a sense of anxiety. A tornado was probably forming in this place.
00:18Indeed, in a blink of an eye, three huge clouds in the shape of a funnel were heading towards them.
00:24After having led his family into the underground shelter, Keller decided to take another look.
00:29And what he saw horrified him and hypnotized him at the same time.
00:34The tornado was just above his head. But inside the swirling cloud, everything was strangely calm.
00:41The man perceived a strong smell of grass. He had trouble breathing.
00:45He raised his eyes and saw a circular opening just above him.
00:49It was between 15 and 30 meters in diameter and about a kilometer high.
00:54Keller clearly distinguished the walls of the cloud in rotation.
00:57Constant flashes were zigzagging from side to side non-stop, illuminating the scene worthy of a horror movie.
01:04Many smaller tornadoes were forming and detaching from the cloud.
01:09A deafening whistling could be heard.
01:12The next moment, the tornado passed over Mr. Keller's house and destroyed those of his neighbors.
01:20Mr. Keller is not the only person to have seen a tornado from the inside and survived.
01:25But the other survivors were not so lucky.
01:29In 2019, Chris Tuveng, from Dallas, Texas, one day went to a pizzeria without knowing what to expect.
01:37As the pizzas were not ready, he decided to wait a little while.
01:41It was a big mistake.
01:43A powerful tornado fell on the mall where the restaurant was located and dragged him outside the building.
01:49He managed to hang on to a column and prayed for his life.
01:54But what human strength can resist the terrifying power of a tornado?
01:59Tuveng was lifted into the air and thrown onto a truck parked in front of the restaurant.
02:03He tried to hang on to the hood, but there was nothing to grab.
02:07Finally, he managed to hang on to the front left tire and stayed there until the nightmare stopped.
02:13The tornado that Chris survived was measuring, at its base, 13 football fields wide and its gusts reached 225 km per hour.
02:22Eric Simmons climbed into his truck to protect himself from a tornado in May 2019.
02:27Once inside, he looked through his windshield.
02:31Vines seemed to grow along a closure.
02:34It was moving in a strange way.
02:36He felt like he was losing his head.
02:38That's when it all started.
02:40Suddenly, all Eric could see was the wind.
02:44The darkness was total.
02:46Then a layer of roof flew over him and broke into the air.
02:50The rear windshield of the truck also broke and projected glass shards on our man.
02:55A tree in front of him was raised like a twig and the closure was dragged over the truck.
03:01Simmons felt the back of the vehicle lift up.
03:04He saw electric lines exploding under his eyes.
03:07Even if the visibility was bad, he could still see the lightning.
03:11All this lasted about 45 seconds, but it seemed to him that an eternity was running out.
03:17When the road was cleared, Eric got out of his vehicle.
03:20But he could barely walk after the shock he had just suffered.
03:23He couldn't talk either.
03:25It was one of the most horrible and traumatic experiences of his life.
03:29According to him, the reason for his paralyzing terror was that he had not received any training,
03:34that he had not been warned and that he could not defend himself against what was happening to him.
03:39Later, he discovered that the tornado that had almost cost him his life
03:43had a speed between 138 and 177 km per hour and was between 68 and 91 meters in diameter.
03:52A tornado is an air column in rotation that touches the ground.
03:56Sometimes it is connected to the base of a storm.
03:59The wind speed inside tornadoes can reach hundreds of kilometers per hour.
04:04It is therefore not surprising that they have enormous devastating potential.
04:08They tear down cars, roots, trees, destroy buildings, etc.
04:14The problem with a tornado is that it is not always easy to see it coming.
04:18The wind, however violent it is, is invisible.
04:23The first sign of its approach is often the famous rumbling,
04:26which recalls the noise of a train of goods on the move.
04:30There are other sounds indicating the arrival of a tornado,
04:33but the human ear cannot perceive them.
04:37When you see the cone of a tornado,
04:39it means that it has already formed a condensation funnel composed of water, dust and debris.
04:46The most destructive tornadoes are born from rotating storms that are called supercells.
04:52Luckily, meteorologists are able to spot such storms
04:56because they have a well-defined appearance on the radars.
05:00Experts estimate that it is the difference in temperature
05:03that determines the probability of formation of a tornado.
05:07And yet, we still don't know a lot about this process.
05:11For example, the questions of why and where tornadoes are most likely to occur remain unanswered.
05:21Tornadoes are measured using the improved Fujita scale.
05:25The scale ranges from 0 to 5 depending on the damage caused by the tornado and the wind speed.
05:31EF0 is the weakest tornado,
05:34and EF5 is a tornado that you will never meet, I hope.
05:41The EF scale peaks at 290 km per hour.
05:45Solid-structure houses are lifted from their foundations
05:48and transported over long distances before being reduced to rubble.
05:53Cars are thrown into the air over 100 meters away,
05:58and steel-frame constructions are seriously damaged.
06:03Despite the terrifying power and ferocity of tornadoes,
06:07authorities report that even the worst of them have a survival rate of 99%.
06:14But this does not mean that you should not take all the possible precautions
06:18to avoid finding yourself inside one of these monsters.
06:21Do not approach doors and windows.
06:24Take refuge, if possible, in the center of your house
06:27and use pillows, blankets and mattresses to protect yourself from flying debris.
06:32If you are stuck outside during a tornado,
06:34crawl up to a ditch, cover yourself and protect your head.
06:38There is a phenomenon just as frightening as a tornado,
06:41but which is formed in the water.
06:43Turbulences appear when water at high flow hits an obstacle or another current.
06:49The water then begins to swirl in a descending spiral,
06:52dragging all objects, animals and even small boats that are nearby to the bottom.
07:00A tornado can also form when a gulf suddenly appears created by the collapse of a cave, for example.
07:06The water then invades the hollow structure and creates a swirling current,
07:10similar to the one you see when you remove the cap of a bathtub filled with water.
07:15While some tornadoes are small and brief,
07:18others can reach enormous dimensions and be driven by constant currents.
07:23The most dangerous of them are the maelstroms.
07:27If you enter such a swirl, your chances of going back to the surface are slim.
07:32The constant movement of the water and its attraction force disorient you and prevent you from breathing.
07:39This is what happened to Stuart Fullstone when he found himself trapped in a swirl.
07:44His first reflex was to swim, but this idea proved to be unfruitful.
07:49The images filmed by the camera fixed on his helmet
07:52show that the man remained underwater for nearly three and a half minutes.
07:57He was probably dragged all the way to the bottom of the river.
08:00There, the attraction force weakened a little and finally released its grip.
08:05The man was lucky. A kayaker spotted him in the water and brought him back to the surface.
08:11The depth at which a swirl can drag you can vary.
08:15It depends on its power and its size.
08:18Fortunately, all people trapped in a swirl have not survived and have never come out of the water.
08:24The diversity of the ways in which swirls form means that they can sometimes appear unexpectedly.
08:31Impossible to predict anything, you are not warned.
08:35The best way to stay safe is to wear your life jacket at all times when you are in the water.
08:42If you are dragged into a swirl, try not to move in the same direction as the water flow.
08:47Aim for the outer edge rather than the center of the swirl.
08:51If you are lucky, its force will project you upwards. There have been precedents.
08:56If you cross a swirl by boat or kayak, do your best to prevent your boat from filling with water.
