Scientists have found a destructive & # 39; freak wave & # 39; Has entertained, and he is a strange acquaintance



On the Norwegian fringes of the Dreppan oil platform, workers expect the waves to boil things at large. But in 1995 at 3 O'clock on New Year's Day, a monster struck. It makes history.

At an altitude of about 26 meters (about 84 feet), it was a kind of wave that you can expect once in a century. Actually comes out of nowhere that was really a wandering part. Now researchers have hard evidence of the forces involved in the wave formation.

A team of engineers from Oxford and Edinburgh universities crossed the waves in rounded pools in an attempt to create a full storm.

"Measurement of the droppenar wave in 1995 was a symptomatic observation that was researched in the physics of freak waves for many years, and Oxford University engineer Mark McAulister says that only folklore settles in the event of a permanent world of their world.

"By reducing the dropper wave in the lab, we have stepped in a step to understand the possible methods of this phenomenon."

The evil waves that shoot the droppers are really literal legends. As far as the navigator travels into the oceans, different water levels from the blue are reported.

Buce is measuring up to 19 meters in the seafront of the sea deep sea, while the ships can experience waves at an altitude of about 30 meters.

But stigma raises for more naturality than their size. Unlike the types of sworn affidavits imposed by hurricanes and trends, these waves are born from anarchy to interfere with wave patterns, and are crushed without warning.

The 1995 dropper wave was the landmark; Its kind has been recorded by the first scientific instrument, which has been the subject of investigation for the past two decades.

There are two principles of describing responsible physics for rumors, but those best accounts for the dropper are unclear. So researchers created a small version of monster wave under laboratory conditions to verify which types of ripples are really impressive.

In the circular of the 25 meter (82 ft) diameter test tank at the Flowwave Ocean Energy Facility facility in the UK, the team planned their experiment, which was scorching scent from different corners to form a stand-out wave.

They have found the beams of waves passing through 120 degrees, which can force to occasionally pop up huge. Without the crossover, environmental conditions limit the maximum wave height.

You can check the movement of the waves in the following clip:

"This laboratory observation not only gives light on how a famous droppin wave can come, but also focuses on the nature and importance of breaking down the ocean's transit," said Tone van Dan Bremer of Oxford University, a senior researcher of the study.

But to the researchers, it seemed unwanted as well as the classical picture of the famous Japanese artwork.

If you do not know much about Japanese artist Katsushika Hokusai, you may have probably seen his work. 1830 Woodblock Great wave off Kanagawa The broken wave is one of the world's most famous depictions. From T-shirts to mugs, everything looks to hang the wall, it has become a statue.

It is impossible to see how Hokusai actually saw the waves of such tragedies or told them, and thus created the ultimate artwork based on this impression.

In fact, it has been suggested that the artist represents a moment in the history of Japan, because the nation was standing on the banks of the nation by Western culture. A separate wave in the open ocean will be a perfect metamorphosis by changing Japan.

Deliberate intent, artwork still works perfect to describe the horrific nature of evil waves as destructive, destructive forces of nature.

Dropper oil platform was lucky. In order to withstand greater waves than the 1995 New Year's Day disease, it suffered only small losses.

But many other structures and boats are not so lucky, because obscure encounters due to death and destruction.

Studies like this provide a long way in highlighting the magnitude of the tragedy to highlight the more potential situations and hope that coastal travel becomes more safe.
