# Wobbles in the Barriers: Arctic Oscillation (4)

Wobbles in the Barriers: Arctic Oscillation (4)

This is a continuation of my series on the Arctic Oscillation / North Atlantic Oscillation. Links to background material and previous entries are at the end.

In the last entry I suggested that if you were on a bridge overlooking a swiftly flowing creek then you would notice that twigs floating in the water did not move across the current. They are carried downstream along the edge of the current. The purpose of that comparison was to demonstrate how fast-moving, concentrated flows have the effect of isolating one side of the creek from the other. This is true in the creek, and it is also true about jet streams in the atmosphere.

One way to understand the Arctic Oscillation is to think of it as the variation of an atmospheric jet stream. For the Arctic Oscillation the jet stream of interest is the southern edge of vortex of air that circulates around the North Pole (see previous entry). Air inside the vortex often has characteristics different from air outside it. Intuitively for the Arctic, there is colder air on the side toward the pole. If you look at trace gases, like ozone, they are different across the edge of the vortex. The takeaway idea is that the edge of the vortex is a barrier. It’s not a perfect barrier, but the air on one side is largely separated from the air on the other side. In this blog, I describe the difference between a strong and a weak vortex – which is the same as the difference between the positive and negative phases of the Arctic Oscillation and the North Atlantic Oscillation.

Figure 1: This figure is from the point of view of someone looking down from above at the North Pole (NP). Compare this perspective to Figure 1 in previous blog. This represents a strong, circular vortex centered over the pole, which encloses cold air, represented as blue. The line surrounding the cold air is the jet stream or the edge of the vortex.

Figure 1 shows an idealized schematic of the North Pole as viewed from above. This is the strong vortex case, when there is exceptionally low pressure at the pole. Low pressure is associated with counterclockwise rotation in the Northern Hemisphere. This direction of rotation is called cyclonic. This strong vortex case is the positive phase of the Arctic Oscillation. During this phase, the vortex aligns strongly with the rotation of the Earth, and there are relatively few wobbles of the edge of the vortex – the jet stream. I drew on the figure two points, X and Y. In this case, the point X is hot and the point Y is cold. It is during this phase when it is relatively warm and moist over, for example, the eastern seaboard of the United States.

Figure 2 compares a strong vortex and a weak vortex. In both cases, the circulation around a central point is counterclockwise or cyclonic. However, in the weak vortex case, the vortex does not align as strongly with the rotation of the Earth and there are places where the edge of vortex extends southwards. The vortex appears displaced from the pole; it is not centered over the pole.

Figure 2: Examples of a strong, circular vortex and a weak, more wavy vortex. See text for a more complete description.

Whether the vortex is stronger or weaker is determined by the atmospheric pressure at the pole. In the winter, an important factor that determines the circulation is the cooling that occurs at polar latitudes during the polar night.

What determines the waviness or wobbles at the edge of this vortex? The structure at the edge of vortex is strongly influenced by several factors. These factors include the structure of the high-pressure centers that are over the oceans and continents to the south of jet stream. One could easily imagine a strong high-pressure center over, for example, Iceland, pushing northward at the edge of the vortex. This might push a lobe of air characteristic of the middle latitude Atlantic Ocean northward. Since the edge of the vortex is something of a barrier, this high-pressure system would distort the edge of the vortex and, perhaps, push the vortex off the pole. This would appear as a displacement of the vortex and its cold air over, for example, Russia. If the high grew and faded, then this would appear as wobbles of the vortex.

Other factors that influence the waviness at the edge of the vortex are the mountain ranges and the thermal contrast between the continents and the oceans. The impact of mountains is easy to understand. Returning to the creek comparison used above, the mountains are like a boulder in the stream. The water bulges around and over the boulder; the air in the atmosphere bulges around and over the mountain ranges. The Rocky Mountains in the western half of North America are perfect examples of where there are often wobbles in the atmospheric jet stream.

Figure 3: This figure is from the point of view of someone looking down from above at the North Pole (NP). This represents a weak, wavy, wobbly vortex displaced from the pole. The vortex encloses cold air, represented as blue. The line surrounding the cold air is the jet stream or the edge of the vortex. (definition of vortex)

Figure 3 shows an idealized schematic of the North Pole as viewed from above. This is the weak vortex case, when the low pressure at the pole is not as low as average and the pressure is much higher than the strong vortex case of Figure 1. This weak vortex case is the negative phase of the Arctic Oscillation. During this phase, the alignment of the vortex with the rotation of the Earth is less prominent, and there are wobbles of the edge of the vortex – the jet stream. In this case, the point X is cold and the point Y is hot. It is during this phase where it is relatively cool and dry (but potentially snowy) over, for example, the eastern part of the United States.

These figures help to explain the prominent signal of the Arctic Oscillation discussed in the earlier entries (specifically, this blog). That is, when the vortex is weak and wobbly, then there are excursions of colder air to the south and warmer air to the north. This appears as waviness and is an important pattern of variability - warm, cold, warm, cold.

The impact of the changes in the structure of edge of the vortex does not end with these persistent periods of regional warm and cold spells. The edge of the vortex or the jet stream is also important for steering storms. Minimally, therefore, these changes in the edge of the vortex are expected to change the characteristics of how storms move. Simply, if the edge of the vortex has large northward and southward extensions, then storms take a longer time to move, for example, across the United States from the Pacific to the Atlantic Oceans. In the positive phase of the Arctic Oscillation they just whip across. In the negative phase, the storms wander around a bit. A more complete discussion of this aspect of the role of the Arctic Oscillation will be in the next entry. (Note use of dramatic tension and the cliffhanger strategy of the serial.)

 IPCC’s New Estimates for Increased Sea-Level RiseRecently released sea-level rise findings from IPCC project greater increases than earlier forecast, but continuing uncertainties persist, and drawing direct comparisons with past estimates is difficult.Estimates for higher sea-level in coming decades are one of the major “take home” messages from the newly released IPCC report.Projected sea-level rise had been a particularly controversial aspect of the 2007 IPCC Fourth Assessment Report, with many scientists decrying the absence of modeling of dynamic ice sheet movements and arguing that models had underestimated historical sea-level rise. As a result, many had expected treatment of sea-level rise to be the focus of much attention on the new report, and that has been the case.Understanding why sea-level rise now is forecast to be greater, and why substantial uncertainties remain, requires examining the different causes of sea-level rise and the different ways of estimating future sea-level rise using both physical models and evidence from Earth’s geologic past.Global sea levels have increased fairly steadily over the past 130 years, with some acceleration evident over the past few decades. The figure below shows observations both from tide gauges (from 1880 to 2009) and satellites (1993 to 2013), with measurement uncertainty reflecting incomplete coverage of tide gauges shown in grey.......Latest Sea-Level Rise Estimates Still Too Conservative?Despite the higher sea-level rise projections in the latest IPCC report and improved ability of models to reproduce historical rates of sea-level rise, some respected scientists maintain still that even the new AR5 numbers are too low.Their argument primarily boils down to two different approaches: process models, which use climate models and physics to estimate sea-level rise, and semi-empirical models, which include evidence of past sea-level rise (mostly during the last ice age) to help determine the relationship between temperatures and sea level. Process models tend to produce lower estimates, empirical models higher ones.The recently released IPCC Working Group I report discounts empirical models, saying that “Many semi-empirical model projections of global mean sea-level rise are higher than process-based model projections (up to about twice as large), but there is no consensus in the scientific community about their reliability and there is thus low confidence in their projections.” Researchers like Potsdam University Professor Stefan Rahmstorf, who have worked with semi-empirical models, argue that a wholesale discounting of these approaches is erroneous, and represents an overly conservative approach from the IPCC.For now at least, it is still unclear just what exactly future sea-level rise will be, as uncertainty ranges remain large. At the same time, it is clear that the best estimates of future sea-level rise are considerably higher now than they were just five years ago. The level of sea-level rise by 2100 will mostly depend on which future emissions scenario societies follow, and it’s clear that significant efforts to reduce future emissions, coupled with well thought-out adaptation efforts, can significantly reduce future sea-level rise and its damaging impacts.

Can you understand how some could interpret that to mean your plea wasn't offered in good faith?At any rate, I doubt the "insults, speculation, bullying and insinuations" will ever stop here or in any public forum, mostly because those words mean different things to different people. If someone barges in here and says, "You climate change sheeple are socialist liars," is it "bullying" when a half-dozen people deride that commenter for such an inane sentence? If someone states for the 75th time that the planet is cooling as it enters an ice age, is it "insulting" to suggest that person lacks knowledge? If a person quotes from and links to denialist article after denialist article here without ever responding, is it "insinuation" or "speculation" to suggest that he's following to a 'T' the professional denial industry playbook?Many of us will continue to ridicule the ridiculous. So if folks wish to avoid that ridicule, they should stop saying ridiculous things.

 Escaping the warmth: The Atlantic cod conquers the ArcticBremerhaven, 17 October 2013. As a result of climate change the Atlantic cod has moved so far north that it’s juveniles now can even be found in large numbers in the fjords of Spitsbergen. This is the conclusion reached by biologists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), following an expedition to this specific region of the Arctic Ocean, which used to be dominated by the Polar cod. The scientists now plan to investigate whether the two cod species compete with each other and which species can adapt more easily to the altered habitats in the Arctic.Read more >>

 Nuclear Waste Lurks Beneath Arctic IceLarge-scale Soviet nuclear tests, dumping of spent fuel and two scuttled nuclear-powered submarines are a major source of pollution in the Arctic ocean, a Russian research institute has said.There are 17,000 containers and 19 vessels holding radioactive waste submerged in the Kara Sea, as well as 14 nuclear reactors, said a report passed by Russia to the Norwegian authorities in 2012, according to Bellona, an environmental group that acquired a copy of document.As the Arctic thaws under the influence of global warming, oceanic currents in the region could strengthen, carrying the radioactive material to other continents, Alexander Shestakov, head of the Global Arctic Program at WWF, or World Wildlife Fund, said.The sinking of nuclear material and scuttling of ships used to be widespread practice. Of particular worry now is the Soviet nuclear submarine, K-27, scuttled in 1981 in the Kara Sea. The boat, equipped with two nuclear reactors, was filled with bitumen and concrete before being sunk, according to the Russian Nuclear Safety Institute, to ensure that it would lie safely on the ocean floor for 50 years.That period is nearly up. Last year, speakers at a joint seminar with Bellona and state nuclear company Rosatom warned that a nuclear reaction could occur on the K-27."Before that, no-one knew about the danger," Igor Kudrik, a nuclear safety expert at Bellona said.

 Now that were talking...Remember when you posted that JB said "Karen could be a monster"? You never did reference that post Here's a blast from the past to refresh your memory.329. PensacolaDoug 8:41 PM GMT on October 06, 2013 +1 Quoting 278. Neapolitan:Do you have references to show us which credible scientists said that? There was some hypothesizing of the possibility of fewer storms forming overall due to warming, but stronger storms for those that did form. But no one that I can recall actually proclaimed that as fact. I could be wrong, though...At any rate, 2013 has been--so far at least--one of the most extreme hurricane seasons on record in the Atlantic. I'll be very much interested to hear over the next few years to what that might be attributed...Speaking of references. Can you show us where JB said Karen could be a monster? Or is that asking too much? You know, holding you to same standard you want to hold everyone else to. TIA

And in the midst of this important work; humiliating and shaming the same short-list of trolls on the same short list of subjects day-after-day-after mind-numbing day.Sock puppet for science? Why that would be blasphemy.Watching folks wallow around in the mud is much more entertaining though. Thanks, guys/gals/puppets(?)

Without context and previous experience, it would probably jump out to most that a person responded for someone else. Technically, we are all posting behind internet handles to provide some sort of anonymity (although I chose mine back when I had others with a full name), so it's not always straight-forward to prove who is who.I don't agree with Doug on much - it shouldn't come as a surprise - as I think he sometimes comes in here with vague accusations and doesn't get specific. Katrina was directly caused by climate change, anyone?But what I will say is that a situation like this could, at least to some, beg the question. Even though we disagree with him often, I'm not sure that it warrants people piling on the insults. This particular post was probably one of the least-nice ways to convey disagreement. Contrary to many other times, he did actually provide the "proof" he was referring to specifically. How many actually double-checked to see if they were real? I did, and they were right there.I'm not in a place to explain it one way or the other, but maybe we can try to play nicer.If it does turn out that the comments at the Rood and Masters blogs are being pummeled by sockpuppet postings, and somebody exposes it I will be the first to apologize to Doug. It's my understanding that the current brouhaha is over a single first versus third person pronoun issue - a likely typo or brain-fart. Is there more to it than that?

As for the piling on and the insults, I'm a big boy. It wasn't unexpected. I just consider the source. I'm thick skinned.

 Quoting 708. Xulonn:What makes you so think that? The frigid Arctic air might come down to the mid-latitudes and freeze the heck out of the U.S. and Europe, and be warmer up there than normal.Is your statement your "belief" or is there some science behind it? History ,my friend. Science has nada to do with it.

 It’s about Ownership. Why Germany Kicks Butt in Renewable Energy.Cleantechnica:Germany is racing past 20% renewable energy on its electricity grid, but news stories stridently warn that this new wind and solar power is costing “billions.” But often left out (or buried far from the lede) is the overwhelming popularity of the country’s relentless focus on energy change (energiewende).How can a supposedly expensive effort to clean up the energy supply be so popular?1. It’s about the cost, not the priceMost news stories focus on the cost of electricity in Germany, which has some of the highest rates per kilowatt-hour in the world. But they don’t note that the average German electricity bill – about \$100 a month – is the same as for most Americans. Germans are much more efficient users of energy than most, so they can afford higher rates without having higher bills. (Note to self: check out options for energy efficiency).2. It’s about visionGermany doesn’t just have an incremental approach to renewable energy, but a commitment supported by 84 percent of residents to get to 100% renewable energy “as quickly as possible.” A few U.S. states have renewable energy visions (e.g. 33% by 2020, 25% by 2025) that approach Germany’s, but they’re mired in the notion that despite enormous savings to society in terms of health and environmental benefits, renewable energy shouldn’t cost any more today than conventional, dirty energy on the utility bill. Germans have taken the long view (about energy security, price volatility, etc).3. It’s about ownership I lied in #1. Support for Germany’s renewable energy quest isn’t about cost of energy, but about the opportunity to own a slice of the energy system. Millions of Germans are building their retirement nest egg by individually or collectively owning a share of wind and solar power plants supplying clean energy to their communities. Nearly half of the country’s 63,000 megawatts of wind and solar power is owned locally, and these energy owners care as much about the persistence of renewable energy they own as they do about the energy bill they pay. Not only do these German energy owners reduce their own net cost of energy, every dollar diverted from a distant multinational utility company multiplies throughout their local economy.

 Quoting 705. overwash12:I say that ice held up pretty good this summer,gonna be one hell of a winter up there!What makes you so think that? The frigid Arctic air might come down to the mid-latitudes and freeze the heck out of the U.S. and Europe, and be warmer up there than normal.Is your statement your "belief" or is there some science behind it?

 Quoting 706. Xulonn:To believe that both handles belong to the same person would require a high level of incompetence and no ability to think critically. There may be some sockpuppets on the side of science, but they are rare and not at all like like the horde of rabid cockroaches that emerge from the denialist cyberverse to infest the world of AGW/CC blogs....The identity of one commenter at an internet blog isn't going to change the science - nor are multiple denialist sockpuppets at other sites going to change the science...
