Oceanic Oscillations Overview: the Pacific Decadal Oscillation (PDO), El Niño/La Niña, Interdecadal Pacific Oscillation (IPO), Atlantic Multi-Decadal Oscillation (AMO) and the Indian Ocean Oscillation (IOO),
The Pacific Decadal Oscillation (PDO):
El Nino/La Nina, which are closely associated with the Atmospheric Oscillation the Southern Oscillation (SO), is the Oceanic component of the El Nino Southern Oscillation (ENSO);
The Atlantic Multi-Decadal Oscillation (AMO):
The Interdecadal Pacific Oscillation (IPO):
The Indian Ocean Oscillation (IOO), which is closely associated with the Atmospheric Oscillation the Equatorial Indian Ocean Oscillation (EQUINOO) and is the Oceanic component of the Indian Ocean Dipole (IOD). The Indian Ocean Oscillation (IOO) is also closely connected to the El Nino Southern Oscillation (ENSO). (Note, the “Indian Ocean Oscillation (IOO”) does not appear to have a well established name within the literature. It might be better as the Indian Ocean Interannual/Decadal Oscillation (IOIDO), but time will sort that out.):
Earth’s Ocean Circulation system is highly complex and is influenced by an array of variables included:
Earth’s rotation results in the Coriolis Effect and;
imparts Planetary Vorticity on the oceans:
Planetary Vorticity manifests as Ocean Gyres;
the Antarctic Circumpolar Current;
and rotation in the Arctic Ocean:
“Vorticity strongly constrains ocean dynamics.”
“The driving force behind Atmospheric Circulation;
is Solar Energy;
which heats the atmosphere with different intensities at the equator, the middle latitudes, and the poles.”
The movement of gases in response to the resultant pressure imbalances cause wind;
which impacts ocean circulation (particularly surface currents) through Ekman Transport:
Solar Energy also causes Evaporation;
that results in moisture transportation through Clouds;
results in Precipitation;
that results in the Water Distribution on Earth;
creates surface Runoff;
and results in rivers:
However, the impact of river flow on Ocean Circulation should not be over estimated, as “The entire global input of fresh water from rivers to the ocean is equal to about 1 sverdrup (Sv).”;
whereas “The water transport in the Gulf Stream gradually increases from 30 Sv in the Florida Current to a maximum of 150 Sv at 55°W longitude.”
Earth’s Orbit & Tilt
Earth’s orbit around the sun creates seasons, which result in the seasonal building and melting of Arctic Sea Ice;
and Antarctic Sea Ice, and:
helps to drive Earth’s Thermohaline Circulation;
This map shows where cold ocean water is sinking;
this one shows where heat is released to the atmosphere;
and this animation is helpful in visualizing the process:
Earth’s rotation in concert with the moon’s orbit around Earth, Earth’s orbit around the Sun, Earth’s Tilt, Earth’s Wobble and the gravity of Earth, the Moon and the Sun, result in the continually evolving Tidal Force on Earth;
which results in Earth’s Ocean Tide;
and impacts circulation, e.g.:
especially when released by volcanoes;
which have been shown to influence Earth’s climate;
including in the infamous Year Without a Summer;
which was partially caused by the 1815 eruption of Mount Tambora;
and is called a Volcanic Winter:
Such an event might have a significant impact on Ocean Circulation.
Geothermic Energy can also warm the ocean through Hydrothermal Vents;
which can be a factor in Hydrothermal Circulations:
Note that the AMO shows an eerily good recent match to the NOAAs plot of the global average temperature:
Very interesting chart, Nik.
This is a magnificent aggregation of categorized data and charts direct from taxpayer funded collection systems and with easy internet-world access for self examinations. That is particularly utilitarian with the rising sea of troubled science integrity, reporting biases, and debate-has-ended mentality of policymakers and advisers. It levels the playing field in the search for truth and integrity in climate science in a parallel to what the internet does for information sharing in pricing comparison for commerce.
Well Huggy @ 51During WW2 in double short time, the cortnuy went to petrol rationing.That forced all but essential travel onto public transport.It was done in the face of a crisis, and with very simple ration card technology.Conclusion: If our pollies and the public really really really really believed climate change was happening, it could be instituted within a month.If our pollies and the public only really really really believed climate change was happening, it could be instituted over a year or two to allow PT operators to buy more buses/trains.If our pollies and the public only really really believed climated change was happening, it could be instituted over four or five years, to allow PT operators and Governments to buy more buses and trains and do the earthworks/stations/tunnels for upgraded PT networks as well as vehicles.If our pollies only really believed climate change was happening, they would at least ACT as if there were a crisis by leading by example.Guess what, petrol rationing alone would probably get us a long way to a decent target .not by 2020 but by 2014. And it was done in the second world war, so zero excuse for not doing it other than for whatever people say, they actually deep down don’t believe and the pollies are picking up on that loud and clear.Oh, and how about smart metering and control of individual power supplies to limit amounts of (fossil) power consumed after a given amount used per day, current is limited to enough to power a (small) fridge and a couple of lights (exceptions for medical needs perhaps)? No techno breakthrough required implementation within a year, ie 2010 and another step to a deep carbon cut target no need to spend a squillion $$ on consultants to siphon off money designing trading schemes and then another squillion $$ on bureaucrats to administer it a circuit breaker goes *pock* once a residence has overdone its limit or they don’t shut off everything except the fridge and a couple of lights. (How about a card based system that allows people to save’ up for parties and concerts and restaurants where they just chip in for extra power)? Also, if there was a card system for everyone, then those who live in small and efficient homes could sell their credits something that would benefit those with smaller homes rather than those nasty big rich people in their carbon hungry McMansions.Oh well, pigs are oiled up and ready to fly!!!!
Anthony: I just downloaded a copy of Who Turned On the Heat by Tisdale. I wanted to comment on one of the applicable posts earlier which started Dec 3rd and ended Dec 8th where Bob provided a link –however posting is no longer active. The message I would have left is that I downloaded his book in PDF format, and have not read it yet but wanted everyone to know that the quality is very good and the hyperlinks to chapters as well make navigation a breeze. This is an area of the sciences that I find extremely interesting and Bob has proven to be especially good at explaining science in an unassuming and informative way.
Thank you Anthony for providing us with an impossibly well run site/information depot for those of us who yearn for knowledge and who seek respectful debate.
Mario Lento: Thanks for the kind words about the book. I hope you enjoy it.
Off topic, I will agree with you and Michael Schumacher. Ayrton Senna was the best F1 driver. And since those cars will never again be as untamed as they were in the 1980s and 1990s, it’s unlikely there will ever be another Senna.
Ah Bob… I don’t remember where I spoke of these race car drivers… but yes – I would have made those statements. As a racecar driver, coach and instructor – I can have an appreciation of the physics and art required to command such beasts.
Bob: I could not put WTOH down last night…! At around 2AM, I started to get tired at around page 100 –I look forward to getting deeper into it soon. It’s an easy read, and you painstakingly answer all of those questions that I otherwise would have been stuck trying to resolve before I could move forward. I’m talking the ride from the start to finish rather than skipping to different chapters. However, I do notice that you made it possible to start at various chapters since each new section includes the summarization of the background needed to appreciate the what the current chapter reveals. Watching your presentation on Anthony’s broadcast certainly helped me with the big picture of what you’re professing.
It seems, correct me if I am wrong, that you are the sole scientist laying out with clarity, the mechanisms behind the energy balances of the oceans and their affect on climate and weather. I look forward to seeing how you connect solar activity with ENSO. I believe the sun affects our climate as can be seen in many correlations and appreciate the extensive research needed to track cause and effect in a way that can shed light based on observation rather than modelling. Your book is answering questions I didn’t know I had… and transfers the principles such that this engineer can own what seems to be going on –rather than parrot hollow statements.
In science and engineering, I have never liked putting too much faith in models except for their use in showing and proving simple well bounded assumptions. I’ve seen too many brilliant, but ideological, engineers model what they want to prove –regardless of the myriad other unknowns that affect the outcome in the real world. I’ve always been good at poking holes in the models where the modeller was so stuck on the tiniest details that they could not or would not see the bigger picture.
One such model failure required me to jump into someone’s race car and within 3 laps turn a lap time 5 seconds faster than he could ever go and 4 seconds faster than his model proved was the limit! His model for lap times was retarded by his belief system. The only way I could make him admit he did not understand enough about traction, slip angles and lines through corners leading to other corners, to make a model to predict lap times was to sit him in the passenger seat of his own racecar and scare the heck out of him (that was the fun part). My fast lap time was actually 4 seconds faster than his model showed was possible, afterwhich I rested my case.
Im no pro, but I imagine you just crafted an excellent point. You certainly comprehend what youre talking about, and I can definitely get behind that. Thanks for staying so upfront and so straightforward.
Why is the link to the Atlantic sea surface temp chart (1979-present) not working? I look at that one very month.
Looks good to me, am I missing something?
