Greetings,
The same wind against current produces waves effect occurs on the east coast in the Gulf Stream. If there is ANY north aspect to the wind AT ALL you don't go out! Meaning WNW through ENE.
I have heard one theory that suggested a rogue wave sank the Edmund Fitzgerald in Lake Superior.

Greetings,
If one accepts the Peregrine soliton hypothesis it stands that rogue waves can appear in ANY body of fluid, water included due to the double spatio-temporal localization.

The trouble is as far as i know there are no semi conductors, jetties or lens in the middle of the ocean to create the conditions for the formation of a wave. Need less talk, pretty pictures, and more data to answer this question
It seems plausible to have wave sets converging from two or more directions being refracted by a gyre, or a 'lens' of current changes, which then concentrates whatever combined (freak) waves that form.
Previously I had always imagined wave sets which combined but did not vary in their direction. That's the bit that made sense to me.

Mr. 45. Peregrine soliton - Wikipedia, the free encyclopedia Read the link and you may become less of a "dummy" on the subject. "Main Properties" should give you a better understanding.
Waves entering a bay would dissipate as they spread out, as opposed to open ocean waves being concentrated by a gyre 'lens'...right?
wouldnt the jetties, entrance, sea bottom act as a lens? I'm thinking of a bay with a narrow entrance
Yes, but the waves would be from one direction, and would release their energy along the shore.
Heller's point was that, rarely, current conditions or an ocean gyre could focus the energy of several large wave sets into an area of ocean during a storm. Normally these wave sets would cross each other as they normally do, but under these conditions their energy would be concentrated, making freak waves possible.
That's the way I'm reading it...
and that is why i thought of a narrow bay entrance with the jetties which would focus this energy. No open coast line here to dissapate the energy The wave sets approaching from slightley different directions focused by the jetties and lifted by the out going current.
Oh, now I get what you mean...that would be jumpy for sure!
There is a tear drop shaped island here where the waves cross after being bent by the shoreline. After passing the island they cross at about a 30 degree angle, then bounce off a cliff on the mainland about a mile away which makes for 4 sets of waves all crossing at once. They aren't really waves after that...they just jump into existence, throw their tops away in an explosion of spray, then disappear. Crazy!
Scale our scenarios up to open ocean size and conditions, and it paints an ugly picture.

Wave action is a killer as we all know and vessels which are out there day after day suffer terrible unseen damage. Given the issues one must accept some risk, but that risk, especially with the now over sized vessels has to be viewed in a different light. I applaude the Chinese for no allowing the VLBC to deliver iron to its ports/ We should ban similar vessels, oil, container or bulk, using our ports. Bill.
