Here is the paper that was just submitted with a long title "How does the earth system generate and maintain thermodynamic disequilibrium and what does it imply for the future of the planet" by Axel Kleidon. Is this using long title to make you breathless just reading it a new tactic in the new world science?

And this one:
As the giant wave swelled at Mavericks, Sion Milosky paddled into it. He'd caught more than a few when suddenly the lip of a wave he was riding collapsed on top of him. Milosky went down, and the wave crashed over him -- again and again.
After surfing what some called "the session of a lifetime," Milosky, a 35-year-old Hawaiian known as one of the best big-wave riders in the world, died late Wednesday.
That told what had happened. It was an accident, a tragic accident. It's always sad to hear it. Now hundreds of news articles have written about the tragedy. This SFGate short tribute entitled "Surfer Sion Milosky's death atMavericks underscores ocean's force, attraction" is a good one completes with a video monologue. I would like to just show the following short video showing Sion Milosky in action in his memory:
Fifty-foot waves do not discriminate -- especially those that lurch from the deep open ocean at Mavericks, the region's iconic surf break near Half Moon Bay. From world champion surfers such as Kelly Slater to underground daredevils like Sion Milosky, the waves' raw, violent energy places the life of any mere mortal in the balance.
On Wednesday, Mavericks claimed Milosky, a respected 35-year-old Hawaiian with a wife and two daughters back home on Oahu's north shore. Milosky was a welder by trade but forged his truest identity as a fearless charger in the midst of four- and five-story waves, often at remote outer island reefs in Hawaii.

Here's an AP picture showing the vortex of a whirlpool formed by tsunami waves at a port in Oarai, in the state of Ibaraki. Note that there is a small fishing boat caught in the mid of the whirlpool.
And here is the model output of the case:
Now here's the NOAA issued graphic of Tsunami wave heights as it travelled across the Pacific basin.
Our prayers are with all the devastated good people there, may God help them rebuilt their life in earnest blessing and for those lives lost may they all be rest in peace.

While cleaning and sorting out my old emails I came upon a set of emails that re-reading them still give me some personal thrill and satisfaction. That was a few month before I retire from my active duty in April 2007, I received this email:
Dear Mr. Liu,
I am a 5th Grade student at Glenelg Country School in Howard County, Maryland. I am doing my 5th Grade Science project on rogue waves. I have read several articles that you have published on this topic of rogue waves. From what I've read I can tell that you are an expert on these freak waves. I was hoping that you would be willing to answer some questions.
My first question is: What is the biggest rogue wave that you know of?
My second question is: Do rogue waves have to occur as a result of an extreme storm or can they occur in calm waters? After a lot of reading on this subject, I am not quite sure I understand if rogue waves must be born of a storm. I know that another type of wave, a tsunami wave, is usually a result of an underground earthquake.
Thank you for your time.
Yours very truly,
Duty bound, I duly responded with pleasure. Here’s my response:
Dear G Cadoux,
I am thrilled to have received your email and knowing that a 5th Grader would be interested in freaque waves. All power to the Howard County school system.
Regarding your first question, I don't have a ready answer for you. I think you can find an answer easily through, for instance, Google search. The size of waves is not that important. When things go wrong, disastrous damages do not necessarily be caused by very large waves.
Your second question, however, is a very good one. Freaque waves can happen during storm *and* during calm conditions. At the present we do not know what was really causing the occurrence of freaque waves. There are a number of speculations that can lead to freaque wave generation one way or the other. But only speculations. When a freaque wave happen unexpectedly, which can happen any time at any place out there, with or without people around to see it, any number of speculations on their occurrence may or may not be applicable. You are correctly pointing out that Tsunami is caused by earthquakes, which is totally different from freaque waves. Although many adult media types still frequently mixed them up in their reporting.
I am not certain if I have answered your questions. If not, please feel
free to ask me again.

She had a fellow up:
Dear Mr. Liu,
I am thrilled that you answered my questions about freaquewaves. You have answered my questions very fondly and the answers are very important, and also very interesting.
I do have one more question, this question is not on my report but I think it is important. I was on the internet watching a video about a fishing boat on DEADLIEST CATCH DiscoveryChannel, and this man left his video camera on and a rouge wave hit his boat. The rogue wave that hit his boat was as tall as a five storey
building. Have you ever recorded a rogue wave bigger in any way?
Thank you for helping me with my research and it has helped me a lot and sounds very interesting.
And I responded with this
The freaque wave case you saw on the TV show "Deadliest Catch" is obviously true. Waves higher than that one are known to have happened. Not being a sea-going sailor myself, I have not personally seen or experienced any. Waves can do damage not necessarily by its size. Sometimes a few meters high wave can cause disaster at the wrong place and the wrong time. The research on freaque waves is a young field, no one has any substantive answers yet. Mostly speculative. We don't know where or when it will happen or why. We only know that it will happen somewhere, sometime, somehow!

That was the end of my communication with Gabbe. But a couple of month later I received this:
Dear Mr. Liu,
My husband and I would like to personally thank you for responding to our daughter's questions about rogue waves. We are not sure how she came to select this topic for her science report but it proved to be very interesting. Your name frequently appeared in her research so we encouraged her to contact you. You are obviously an international expert on this topic. The fact that you took the time to address her questions was such an encouragement. Thank you again!!
By the way, she received an A++ on the paper. Her science teacher found the subject matter fascinating.
Now here’s my reply:
Dear Mr. and Mrs. Cadoux,
Thank you very much for your email. I am delighted to hear that Gabbe received A++ for her paper on rogue waves. Please extend my heartfelt congratulations to her.
There are plenty of activities in a research scientist’s life that’s routine and predictable. But communication with a 5th grader on a science topic is definitely not among them. I was truly thrilled to encounter a 5th grader who’s interested in rogue waves. And she asked very thoughtful questions. It was an enchanting experience for me.
Paul C. Liu
Gabbe should be in high school by now. I am certain she'll be happy and successful where ever or whatever she chooses to pursue. All the sincere best wishes to her continued success. Life's happiness and satisfaction sometimes simply come from just doing one's job and be ones own self!

Now for the freaque wave watchers, pay attention around the 2:40 time mark:
They characterized their beach wedding as "unlucky" and a news article even called it "disastrous' but I think they are in fact really very lucky, it's all happened manageably, no major mishaps. Especially when they went back to the beach for the pictures two days later on a nice day and encountered that freaque wave and both of them being swept on the beach. They are very lucky because that's all that had happened. Plenty of unlucky stories also happened that way. I saw a good numbers of Youtube beach weddings had took place, some even involved children. I guess Coast Guards are duly notified and be ready for anything that might happen. I sincerely appreciate Kathleen and Bryan chose to share their experience with us strangers. All the best wishes and lifelong happiness to them. I certainly would not advise any of my love ones to do something like that no matter how adventurous and well prepared they are at any circumstances.

Never thought of freak waves until Father's Day 2008 when we received a call in Alaska that our son Jeremy had an accident. He was working with Youth With a Mission in Australia and he was at the beach that day showing his friends where he wanted to propose. The boys went down to walk on the rocks when a freak wave washed them in...our son Jeremy was never found.She referred me to a website called onetwentyone.com for details. I actually blogged here two years ago about Jeremy's case shortly after it happened when Jeremy was still considered as missing and the search was still ongoing. Here's my comments made at the time:
The same familiar plot again: walking along coastal rocks when a freak wave washed them away!My misgivings are still the same: no one in the academia and the governments seem to really concerned enough on providing resources to learn more about the happenings even when tragedies happen so frequently. I wish to thank Mrs. Earnshaw for reminding us this tragic case. I was intrigued by the website called "onetwentyone". It is in fact an important part of Jeremy's story:
The Australian police had already told the parents to “prepare ourselves for the inevitable, that he probably is not alive”. Let our best wishes and prayers be with the parents, miracle can happen and hope it can happen to this family.
Walking along a beach or coastal area is the most enjoyable thing and it can be peaceful and tranquil. Why can't we make it stays that way? We can explore Mars and go to the Moon, but no one cares to do something to make our beach and coast safer for human life. Why?
Jeremy had made numerous trips to Australia since 2003, working with the youth and studying at the Newcastle Youth With a Mission base. As part of his training, Jeremy participated in a mission excursion, working in orphanages in Cairo, Egypt. Before he left for Cairo, Jeremy decided to put a tattoo on his chest of Philippians 1:21, "For me to live is Christ, to die is to gain.”I am sure that Jeremy is in a much better place now and he'll be continuously pray for us!
