'Rogue waves' reported by mariners get scientific backing

"In the next phase of research, a project called Wave Atlas will use two years of "imagettes" to create a worldwide atlas of rogue wave events and carry out statistical analyses, ESA said."

Predicting rouge waves would be invaluable.

These threads seem to be coming in waves!

[Experiment 6-2-6]

I remember a rogue wave. Came off our stern, and the poor sailor who was the stern watch was waist deep in water.

My squadron had a ship head into Japan to have repairs done, and two sailors went to the stern to do some maintenance. Rogue wave came, the railing didn't keep 'em onboard. They retreived one sailor with a broken arm. We spent two days searching, but never found the other.

This is very interesting.

Apparently it defied the "conventional scientific wisdom" and wasn't believed, until now, when they have irrefutable proof.

I wonder what is causing them.

Cowabunga, Dude!

Old salts talk about a Devils' Wave at Monterey. The waters are calm. Then, out of the blue, a giant wave appears and destroys fishing ships. There are mysteries in the sea yet uncovered. FReegards....

[Arthur Wildfire! March]

One possible cause is underwater earthquakes. Gasses could cause pressures. Large, deep underwater caves could cause periodic pressures as the water streams around inside them at different lunar cycles. And God-knows-what.

To see them from Satellites they must be huge.

"Wonder what's causing them.."

I recall an article in Reader's Digest about 30 years ago..
A cadet training vessel, a sailing ship, was capsized at sea by what was believed to be a rogue wave..

The theory has been around a long time that it is "convergence", that waves can meet, and add their strength together..
With the proper conditions, the additive affects create these big boomers..

Another article I read on this subject noted the large waves that precede hurricanes, and pointed out that ocean currents and even weather fronts can contribute to abnormally large waves.

Still plenty to learn about the world we live in, let alone the universe..

My first cruise to the Mediterranean, on a navy destroyer, saw swells up to 100 or more feet. No damage and no reports of damage to other ship in the sixth fleet. We never saw that kind of water again.

Isn't that what you get when Tammy Faye Baker entered a room?

Normal waves in the ocean are caused by when wind blows across the water's surface. The wave height is determined by wind speed, fetch, duration, and the water's depth.

Here is a wave machine. Play with it to see how high you can make a wave.

The prevailing theory holds that freak waves can result when strong, high storm waves slam headlong into a powerful current traveling in the opposite direction. The interaction can push together the storm swells, so that their frequencies superimpose, creating one tremendously powerful wave that can reach a height of 100 feet or more.

97 feet was my best effort.

[CollegeRepublican]

Yeah, that is as high as it goes. I wish it would let you have more variablility in the wind speed. Like increasing it to 75 knots or so. Similiar to Hurricane strength winds.

[Doctor Stochastic]

Also here.

The theory of singular waves has been around for many decades. This article points out more observations (more that can be seen from ships, that is.)

Not a ping, just a catastrophism topic added to the catalog.

"Rogue waves" have been the anecdotal cause behind scores of sinking's of vessels


I thought it was Sea Monsters.
