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.)

Al Gore, carbon hypocrite

• 8:52 am, May 12th, 2013

Since Al Gore has been trashing Canada, again, while on his latest book tour, today I will trash Al Gore.
Let's begin:
1. While preaching energy austerity for everyone else in order, he claims, to save the planet from man-made climate change, Gore personally lives a luxurious, jet-setting, carbon dioxide-consuming lifestyle, including multi-million-dollar homes and never-ending, first-class, globe-trotting. Telling others to "do as I say, not as I do" - is the classic definition of a hypocrite and it describes Gore to a T.
2. While constantly denouncing the evils of the fossil fuel industry, Gore recently sold his Current TV for $500 million (including a reported personal profit of $70 million) to Al Jazeera, the international news service funded by the oil-and- natural-gas-rich Arab emirate of Qatar. See the definition of a hypocrite, above.
3. Gore compares Canada's oil sands to an "open sewer," despite knowing full well the single greatest driver of man-made climate change in North America today, if the theory of anthropogenic global warming is correct, is America's use of coal, particularly to generate electricity. By contrast, Canada's use of coal is relatively insignificant, given that, unlike the U.S., most of our electricity generation comes from hydro and nuclear power, which do not emit greenhouse gases. Even prominent Canadian climate scientists who are no fans of the Stephen Harper Conservative government, have acknowledged development of the oil sands is an insignificant contributor to global warming, and that the global use of coal, particularly to generate electricity, is by far the greatest threat to the climate.
4. Gore and Bill Clinton are mainly responsible for the fact the U.S. never implemented the Kyoto accord on global greenhouse gas emissions. After the Clinton-Gore White House agreed to Kyoto in principle, it never tried to ratify it, the legal measure required to bring it into effect. This was due to the fact the U.S. Senate voted unanimously, 95 to 0, to refuse to ratify Kyoto until it established mandatory emission cuts for China, India and the rest of the developing world. Instead of working to build political support for Kyoto, Clinton and Gore adopted the Senate's position opposing Kyoto as their own. That continued to be U.S. policy through the George Bush and Barack Obama administrations, right up to the expiration of the Kyoto protocol at the end of 2012. Hypocritical North American environmentalists and Canadian opposition politicians who constantly denounce Canada for legally withdrawing from the Kyoto protocol in 2011, never mention the U.S., starting with the Clinton-Gore administration, never even joined Kyoto.
5. While Gore routinely bashes the Harper Conservatives, in 2009 he said in Toronto that then Liberal Ontario premier Dalton McGuinty's green energy program was "widely recognized ... as the single best green energy (program) on the North American continent." In fact, McGuinty's green energy program has been an utter disaster, saddling Ontarians with billions of dollars of extra costs on their hydro bills for generations to come, according to Ontario's non-partisan Auditor General, as well as costing thousands of jobs. McGuinty's Green Energy Act took away the rights of citizens to object to industrial wind turbines being rammed down their throats across Ontario. At the same time, the McGuinty government caved in to political pressure and cancelled gas plants in Mississauga and Oakville (also part of the Liberals' green energy program), costing taxpayers at least $585 million, in order to save a few Liberal seats in the last election.
6. Gore's 2006 film An Inconvenient Truth, for which he won the Nobel Prize and an Academy Award, is a train wreck when it comes to scientific accuracy. It wrongly projects massive sea level rises which no credible scientific body supports and constantly confuses "weather" and "climate." It inaccurately blames individual weather events, such as specific hurricanes, on man-made global warming, and misleadingly links anthropogenic climate change solely to such hot weather phenomena as heat waves and droughts. In fact, climate experts say, global warming can also cause record snowfalls and cold snaps. Finally, the movie glosses over the enormous threat to human health and well-being of suddenly moving industrialized economies off fossil fuels, and of preventing developing nations from using fossil fuels to industrialize.
Indeed, the real inconvenient truth about Al Gore is that he is a carbon-spewing hypocrite who has been getting a free ride - particularly from an uncritical Canadian media - for far too long.

Al Gore segment on Hannity's America showing the eco-warrior taking a luxury private jet in late August. Other hypocrisy also exposed.


After long years wading through the knee-deep B.S. with which denialists have covered the place, I've become aware that the number of mentions of Al Gore in any particular denialist passage is inversely proportional to the amount of value or accuracy that passage contains. The passage above cites Gore's name 15 times, plus contains a badly-drawn caricature. I thereby bestow upon it my highest honor:

I think Al Gore is a hypocrite
Sheesh, I know I'm verbose, but that comment was a monster piece of silly claptrap. However, I was able to condense your "monster" comment into 7 words.

Do you have a crush on Mr. Gore that makes you pay so much attention to him? Do you feel good - perhaps even giddy - when you hit the Enter key after such a composition?

And why on earth would you post such claptrap in the comments section of a climate science blog?

Most of the people here who are capable of critical thinking and understanding science very rarely mention his name - except to respond to climate denialists who are enthralled and captivated by him.

And of course, as any intelligent and informed person knows, Al Gore is not a climate scientist. His hypocrisy does not have any impact - or even influence - on the settled science of AGW/CC.

Thanks Daisy. I've got grand master denialist Yoboi on ignore, but I guess those of you who still see his denialist b.s. should have the rest of my comment at the ready to counter his latest cut and paste claptrap. When I fully realized that he never applied critical thinking, and was simply lying about his desire to learn about the hard science that supports AGW/CC, I just gave up on him and used the ignore feature.

I think the concept of scientific uncertainty and the use of error ranges, and the lack of application and use of the concepts of absolute certainty and "proof" is beyond the ability of most denialists to comprehend. I don't mean that as an insult, but rather as an observation.

The academic peer review process is vastly superior to the lack of any critical review and quality standards practiced by the denialist community.

To paraphrase an old saying, "The price of scientific truth and reality is academic rigor and eternal vigilance." Although denialists and charlatans jump on every sign of self-criticism and awareness in the scientific community, and of a lack of perfection in human endeavors as a sign of weakness, hard evidence and truth are on our side. As with AGW/CC itself, the ignorati would see even a 99% confidence levels in rigorous academic peer-review as an indicator of failure, while e=their <1% accuracies are seen as absolute proof of their perspective. Pathetic!

Australia’s Bushfire Season Turns Sydney’s Skies Orange

Australia has been enduring its hottest year on record, and the warm temperatures combined with dry conditions have sent wildfires whipping across the southeastern Australian state of New South Wales. The fires — some of the worst in a decade — have caused a deep haze to descend over Sydney and spurred the deployment of hundreds of firefighters across the region.

All you need to know about Wyatt and Curry in two images:
It looks like Wyatt and Curry is basically an exercise in mathturbation.
It seems that the quality of the "peer-reviewed" papers - like the current one from Wyatt and Curry - from the "pay-to-publish-yourself" are quite inconsistent. Some are quite good and well received - typically from authors who also are published frequently in major traditional scientific journals with rigorous peer review.

However this paper, and the truly awful recent one on "GW has stopped" that caused two of the paid "reviewers" to quit to protect their reputations, seem to be bottom of the barrel stuff.

Unfortunately, bad science, and even outright hoaxes, get published (rarely) in traditional respected academic journals as well, but it seems easier to publish bad science in the "open access" pay-to-publish variety of journals.

Bottom line, simply because something is peer-reviewed does not mean that it is infallible - but the "respectable" traditional academic journals seek to both refuse bad science, and in the rare instance that bad science gets by peer-review process and is exposed - they purge the paper from their archives and acknowledged the errors.

There's a good discussion of this at The Guardian that was published this month. The comments are excellent - mostly by working researchers. I want to read them more thoroughly this evening. I really appreciate their focus on the value of "open access" - the big advantage of the pay-to-publish journals over the "free-abstract, but expensive to buy and read" model of the traditional journals.

Open access is good, but pay (bribe?) to publish can be bad in my estimation. There is too much incentive to publish bad science under the pay-to-publish system, which are - I believe - consists of companies that simply exist to make a profit from publishing - with no grounding an underlying ethic that is based on the advancement of scientific knowledge.

I think this is a very important subject, and hope that some of you will read the article and comments at the above link. I would like to be able to refine my knowledge of this split peer-review system, and be able to discuss it with confidence when the issue of "peer reviewed" science come up here and at Dr. Masters' blog.

From the Vancouver Sun:
Canada’s efforts accelerate a global tragedy of the climate commons

Stephen Harper’s statement that Canada “won’t take ‘no’ for an answer” regarding the impending U.S. decision about the Keystone XL pipeline overlaps inauspiciously with a new study in Nature this week, which projects that, within a generation, known climates in most regions of the globe will be a “thing of the past”.

University of Hawaii ecologist Camilo Mora and his co-authors project that the recent increase in extreme weather events is merely the prelude to the next half century’s “unabated heat wave” as, under a business-as-usual scenario, climate moves wholly outside its range of historical precedence. Wholesale climate shifts will occur soonest in the tropics, where most of the world’s population and much of its biodiversity live. The punchline? Says Mora, “any progress to slow ongoing climate change will require a larger commitment from developed countries to reduce emissions.” Yet Canada’s Prime Minister is leading the charge instead to accelerate carbon emissions from oilsands.

It depends, george. Using a specific event is, of course, nonsensical. However, using that event to point out the upward trend in extreme weather, and pointing out that that is consistent with projections, seems reasonable to me. (I will grant that a lot of such posts fail to do the latter, though.)

From Open Mind:

The ICP report

Many of you are probably aware of a “report” which is intended to contradict the IPCC (Intergovernmental Panel on Climate Change) report. Its authors call it the “NIPCC” report for “Non-governmental International Panel on Climate Change.” It’s supposed to represent the very best that so-called “skeptics” have to offer.

But in my opinion, a much more accurate acronym would be “ICP” report — for “Intentional Cherry-Picking.” You don’t have to look any further than their “Summary for Policymakers” (SPM) to see cherry-picking taken to the extreme. And I do mean, extreme. One of the most obvious, most egregious, and frankly most ridiculous examples is Figure 4 from their SPM. It looks like this:



Here’s what they have to say when referring to this figure:


“… a wide variety of datasets other than the HadCRUT global air temperature curve favored by the IPCC do not exhibit a warming trend during the second half of the twentieth century. See Figure 4.”


Let’s find out whether or not their claim is correct. ...

Grab some popcorn and watch the carnage ensue.

DemocracyNow.org - In part two of our interview with ousted president of the Maldives, Mohamed Nasheed, he describes the battle for democracy in his country after he was forced out at gunpoint in February. To his surprise, the United States instantly recognized the man who took his place, former dictator Maumoon Abdul Gayoom. Nasheed was a longtime pro-democracy activist who was jailed for six years under Gayoom's rule. The coup became news across the globe in part because Nasheed has become an internationally recognized leader in the effort to address the root causes of climate change. The Maldives rise just 1.3 meters above sea level, making his nation and other island states extremely vulnerable from rising sea waters due to global warming. We also speak with Jon Shenk, director of a new documentary about Nasheed's life, "The Island President," which is now playing in theaters.

Nah, I've had enough of the multiple handle nonsense. Today I was accused of being FLWolverine, before it was Neapolitan. MisterPerfect is no CEastwood, he's just misguided, most likely from reading Climate Depot articles. That's enough to drive any man crazy.


Yeah, I wanted to see the list, find out who my sock Puppet is.

MisterPerfect and NRAamy both bragged on Aaron's blog about all the other handles they have. I think they made a lot of the troll handles here. If you google their handles and look back at their old comments it's obvious they're both racist psychos.

Quoting 311. MisterPerfect:


Al Gore IS propaganda.


No one ever mentions Gore here other than you and CEastwood. We really don't care. We discuss the actual science behind AGW, and tend to post published papers on the subject, none of which study Al Gore.


The first article, despite being from the bought and paid for "Climate Depot" doesn't even have anything to do with global climate. However, to the untrained eye, I'm sure it looks like he just "beat" AGW.

re:301

Here we go again... one year does not a climate make. A lot of slick graphics fool no one who can look up the climate trends. And- did you know that there is a whole big world out there? Not just the US? What about the flooding in Alberta, and in Colorado for that matter? Drought in New Zealand? Heat in Australia?

Mister aint perfect. ClimateDepot is a well known hack site that only denier sheep takes seriously.

You have to be a complete crackpot to believe that Newton and Einstein are wrong about gravity.
