Scientists have created a devastating "birth wave" in the lab, and it is strangely familiar



At the Draunner oil rig off the coast of Norway, workers will expect the big waves to shake things from time to time. But at 15:00 on New Year in 1995, the monster hit. She made a story.

On top of nearly 26 meters (about 84 feet), it was the wave that could be expected once in a century. The real confusing part was that it came from nothing.

A team of engineers from the universities of Oxford and Edinburgh sent waves, crossing into a circular pool, in an attempt to create a perfect storm.

"Draperner's wave measurement in 1995 was an initial observation that initiated many years of research into the physics of waves and transforming them from ordinary folklore into a reliable phenomenon from the real world," said engineer Mark McAllister of Oxford University.

"By recreating Draunner's wave in the laboratory, we have moved a step closer to understanding the potential mechanisms of this phenomenon." As seafarers descend into the ocean, there are reports of isolated mountains of water rising from the sky.

Bums measure waves up to 1

9 meters in the loneliness of the deepest oceans, while ships are known to encounter waves nearly 30 meters high.

But the fraudsters are distinguished by their spontaneity more than their size. Unlike those that rise from storms and currents, these waves are born of the chaos of the disturbing waves that are noticed without warning. the first of its kind to be recorded with scientific instruments, which has been the subject of an investigation over the past two decades.

There are two theories describing the physics responsible for fraudsters, but which of these best reports about Drawner is unclear. That's why the researchers built a miniature version of the monster wave in the lab to check what kind of waves create something really impressive.

They found banks of waves crisscrossing at 120 degrees, which could make the casual giant appear. Without this crossover, environmental conditions impose a limit to the maximum wave height.

You can check the motion of the waves in the clip below: "Not only that this observation lab sheds light on how Draunner's famous wave has emerged, but also highlight the nature and importance of wave formation in crossing the marine environment, says senior research investigator Ton van den Bremer of Oxford University, the scammer's wave mirrors actual fraudulent waves photographed on the open sea, making the team confident that they are on the right track [19659003]

But for a researcher they also looked unusual as a classic image of famous Japanese artwork

Even if you do not know much about the Japanese artist Katsushika Hokusai, you have probably seen his work .. The wood of 1830 The Great Wave of Kanagawa ranks among some of the world's most famous images of a breakable wave, appearing in everything from t-shirts to cups to walls, it becomes an emblematic image. It is impossible to say whether Hokusai has actually witnessed such fraudulent waves or he has heard them described, and thus created the last work of art based on these impressions.

In fact, it is supposed that the artist is a moment in Japanese history, as the nation was on the brink of being overwhelmed by Western culture. Breaking the isolated wave into the open ocean will be the perfect metaphor for changing Japan. Aside from intentions, the work still does a perfect job of illustrating the terrifying nature of unfair waves as unpredictable, destructive forces of nature. 19659003] The oil platform Draupner was lucky. Built to withstand waves bigger than the New Year's scammer in 1995, it suffered only minor damage.

But many other structures and ships were not so happy with homeless meetings that caused death and destruction. this time a long way to clarify the conditions that make the fraudsters more likely and hope to make ocean travel much safer.
