# Barriers in the Atmosphere: Arctic Oscillation (3)

Barriers in the Atmosphere: Arctic Oscillation (3)

I want to continue with the Arctic Oscillation / North Atlantic Oscillation. First, however, here is the link to my August presentation. Also here is a link to the GLISAclimate.org project workspace where I collected together the materials I used in the presentation - Arctic Oscillation: Climate variability in the Great Lakes.

Here are the previous entries in the series:
Behavior
Definitions and Some Background

This blog is mostly a setup for the next one. (And yes I did notice that the IPCC AR-5 report was released, but I don’t have anything different to say about it than many of my more able colleagues. I’ll get to it.)

In the talk that I linked to above, I used a couple of diagrams that the audience told me worked very well. I am going to try them out in this blog. In the previous blogs I used the CPC Climate Glossary to give the definition of the Arctic Oscillation. “The Arctic Oscillation is a pattern in which atmospheric pressure at polar and middle latitudes fluctuates between negative and positive phases.” This definition does not really do much for me. It’s one of those definitions that I imagine if I ask 10 atmospheric scientists to tell me what it means, I will get 12 answers. Therefore, I will draw a picture.

Figure 1: Adapted from Jim Hurrell – This picture is a schematic representation of the positive and negative phases of the Arctic Oscillation. In the positive phase the pressure is low at the pole and high at middle latitudes. This is the positive phase because if you calculate the difference between middle and high latitudes it is large. In the negative phase the pressure is not as low at the pole and not as high at middle latitudes. This is the negative phase because if you calculate the difference between middle and high latitudes it is small. The refrigerator suggests that this is like opening and closing the refrigerator door (see Behavior).

This figure helps me with the definition. I want to focus on the low pressure at high latitudes, which in this figure is drawn idealistically at the pole. In reality, it is likely to wander off the pole, a fact that will be important in the next blog. When the pressure is low at the pole, then there is a stronger vortex of air circulating around the pole. When the pressure at the pole is not as low, then there is a weaker vortex. In both cases, strong or weak vortex, the air generally moves from west to east.

For clarity, vorticity is a parameter that describes rotation in a fluid. A vortex is a feature in a fluid dominated by vorticity – that is it is rotationally dominated. Tornadoes and hurricanes are weather features that we often call vortices; there is an obvious circulation of air in these features. In the Earth’s atmosphere at middle and high latitudes rotation is an important characteristic of the flow, due to the rotation of the Earth. The reason air moves in the west to east direction for both the weak and strong vortex cases of Figure 1 is that the rotation of the Earth is important to the flow.

In Figure 2 I have set up an even more idealized figure. I also provide this link to a Powerpoint animation, that I am not smart enough to incorporate into the blog. In the animation I have five slides that clarify the point that I make in Figure 2.

Figure 2: A vortex and a ball. In the center of the figure is low pressure, meant to be an analogue to the vortex over the pole in Figure 1. Parcels of air move around the low pressure system. If it takes the same amount of time for a parcel farther away from the low pressure center to go around the vortex as a parcel nearer the center, then the parcel farther away has to go faster because the distance it has to go is longer. That is why I drew that arrow, saying that air moves “faster” at the outside edge of the vortex.

To set my point a little more, imagine you are on a bridge overlooking a running stream. If you drop a stick in the water near the edge where the water is moving slowly, then if the stick drifts towards the more rapidly flowing water, it is carried downstream at the edge of the fast moving water. It does not cross the core of fast moving water – this jet of water. In fact the jet is something of a barrier that keeps material from crossing the stream. Material is transported downstream.

Back to Figure 2: Imagine that you want to roll a ball into the center of a vortex. As the ball gets to the edge it gets caught up in the flow and pulled around the edge. It does not roll into the center. Look at the this link to a Powerpoint animation to get a better idea of what’s going on.

Now go back to Figure 1. The vortex in Figure 1 is also a barrier. The southern edge of vortex is a jet stream. Air on the two sides of the vortex often has different characteristics. Intuitively, there is colder air on the poleward side. 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 air on one side is largely separated from the air on the other side. In the next blog, I will describe the difference between the strong and the weak case and its relevance to weather, climate and, perhaps, climate change.

 By 2047, Coldest Years May Be Warmer Than Hottest in PastIf greenhouse emissions continue their steady escalation, temperatures across most of the earth will rise to levels with no recorded precedent by the middle of this century, researchers said Wednesday. Scientists from the University of Hawaii at Manoa calculated that by 2047, plus or minus five years, the average temperatures in each year will be hotter across most parts of the planet than they had been at those locations in any year between 1860 and 2005.To put it another way, for a given geographic area, “the coldest year in the future will be warmer than the hottest year in the past,” said Camilo Mora, the lead scientist on a paper published in the journal Nature.

 Has The Media Failed Us In Climate Change Reporting?SXSW Eco Panel Highlights Media's Climate Change Coverage, Or Lack ThereofHow can the media do a better job reporting on the rapidly growing problem of climate change? Some of the country's leading climate journalists are coming together at this year's SXSW Eco festival in Austin, Texas to try and answer that question.John Metcalfe (The Atlantic Cities), Kiera Butler (Mother Jones), Suzanne Goldenberg (The Guardian), Phil Plait (Slate) and HuffPost's Kate Sheppard will join moderator Chris Mooney to discuss the current state of climate change coverage in the media, or lack thereof, as the Obama administration ramps up discussion of the global issue and news outlets paradoxically scale back environmental coverage.HuffingtonPost.com

 As climate changes, animals move fast to escape the heat.Australia is already feeling the effects of climate change, with record-breaking temperatures not just over summer, but over the past 12 months as well. Research suggests that such events are many times more likely thanks to climate change.The IPCC fifth assessment report on climate science found evidence for climate change is unequivocal. The impacts of increasing frequency and intensity of extreme weather events on people and our environment are real and undeniable. But what’s happening to our animals and plants? Our research in Queensland is starting to give us some clues.Read more at uknowispeaksense...

 Quoting 144. Naga5000:Bravo L.A. Times. They will not be publishing letters from climate deniers. Link" I’ll concede that, aside from my easily passing the Advanced Placement biology exam in high school, my science credentials are lacking. I’m no expert when it comes to our planet’s complex climate processes or any scientific field. Consequently, when deciding which letters should run among hundreds on such weighty matters as climate change, I must rely on the experts — in other words, those scientists with advanced degrees who undertake tedious research and rigorous peer review. And those scientists have provided ample evidence that human activity is indeed linked to climate change. Just last month, the Intergovernmental Panel on Climate Change — a body made up of the world’s top climate scientists — said it was 95% certain that we fossil-fuel-burning humans are driving global warming. The debate right now isn’t whether this evidence exists (clearly, it does) but what this evidence means for us." - Paul Thornton (Letter's Editor for the L.A. Times)From the LA Times link -Simply put, I do my best to keep errors of fact off the letters page; when one does run, a correction is published. Saying “there’s no sign humans have caused climate change” is not stating an opinion, it’s asserting a factual inaccuracy.Exactly, a policy all journalists should use.

 Quoting 150. RevElvis:Up to Five Billion Face ‘Entirely New Climate’ by 2050 - From Climate Central's Andrew FreedmanSnipDr. John Abraham has commented on this paper at SkepticalScience:Global warming – a world of extremes and biological hotspotsAn article just published in the journal Nature has helped advance our understanding of climate extremes and how the Earth of the near future will differ from our world as we have come to know it. We all know that as the climate warms, we will see more extremes – extreme heat and drought, storms and flooding – depending on where you live.Regardless of the cause, it would be useful for policy makers and city planners to know when the future climate will depart from its normal variability. How much time do we have to act? A decade? A century?This very question was the focus of the recent paper. The authors (Camilo Mora and colleagues at the Department of Geography, University of Hawaii) used the complete set of available climate models to calculate the year when the Earth's climate will move beyond what we have experienced in our recent past. In other words, in what year will the climate become more extreme than the year of the most extreme events we have witnessed in the last 150 years?They looked at seven different climate variables, including temperature, precipitation, and ocean acidity. According to their results, the climate of the Earth will depart from its normal variability about 35 years from now (in approximately 2050) under business as usual human activity. On the other hand, if we take seriously the threat of climate action, we can push that date by some 20 years.But this global average threshold is only part of the story. The authors recognized that climate change will occur more rapidly near the poles (for instance, temperature changes will be greater near the poles than in the tropics). However, the present climate in the polar regions is already more variable, and biologic systems and humans living there are more adapted to climatic shifts.Read more...

 TEPCO Workers Remove Wrong Pipe Get Splashed With Radioactive Water"A day after TEPCO workers mistakenly turned off (post #64) cooling pumps serving the spent pool at reactor #4 at the crippled nuclear plant comes a new accident - 6 workers apparently removed the wrong pipe from a primary filtration system and were doused with highly radioactive water. They were wearing protection yet such continuing mishaps and 'small mistakes' are becoming a pattern at the facility."Slashdot.org*editFukushima has 'new leak of radioactive water which may have entered the Pacific OceanTEPCO spokesman Masayuki Ono told an urgent news conference Thursday that the overflow occurred at a tank without a water gauge and standing on an unlevel ground, slightly tilting toward the sea.Experts have faulted TEPCO for sloppiness in its handling of the water management, including insufficient tank inspection records, lack of water gauges, as well as connecting hoses lying directly on the grass-covered ground.dailymail.co.uk

 Up to Five Billion Face ‘Entirely New Climate’ by 2050 - From Climate Central's Andrew FreedmanMap of multi-model mean results for different greenhouse gas concentration scenarios of annual mean surface temperature change in 2081– 2100.Credit: IPCC Working Group I. The mean annual climate of the average location on Earth will slip past the most extreme conditions experienced during the past 150 years and into new territory by between 2047 and 2069, depending on the amount of climate-warming greenhouse gases that are emitted during the next few decades, a new study found. The study, published Wednesday in the journal Nature, used a new index to show for the first time when the climate — which has been warming during the past century in response to manmade pollution and natural variability — will be radically different from average conditions during the 1860-2005 period.The study shows that tropical areas, which contain the richest diversity of species on the planet as well as some of the poorest countries, will be among the first to see the climate exceed historical limits — in as little as a decade from now — which spells trouble for rainforest ecosystems and nations that have a limited capacity to adapt to rapid climate change.According to the study, conducted by a team from the University of Hawaii, about 1 billion people currently live in areas where the climate will exceed historical bounds of variability by 2050. This number would rise to 5 billion people under a business-as-usual emissions scenario, which is the emissions path the world is currently on.Even more strikingly, the study found that the oceans, which have absorbed about half of the manmade carbon dioxide (CO2) emissions since the dawn of the industrial revolution 250 years ago, exceeded their historical bounds of pH measurements back in 2008.ClimateCentral.org

I really do not think that you want to see the big picture. I think you are doing everything within your means to not see the big picture, Yoboi!What is wrong is that there are too many people that will refuse to look at the evidence of agw straight in the face! Their ideological and theological mindset prevent them from looking at the actual evidence! You are afraid of increased taxes, but yet you show no fear of the costs that will be associated with adaptation? This will be only for the species that are even capable of adapting. You are afraid of government control now when in the near future every democratic government is likely to fall to mob rule, in the not so distant future?Here is a new prediction for you to ponder, Yoboi. 'Uncomfortable' climates to devastate cities within a decade, study says . The study, unfortunately, is behind a pay wall . I am frustrated, beyond belief, when such important papers are behind a pay wall! Now this is a study that makes a prediction concerning the fairly near future. Should this prediction validate then it will already be too late for mitigation to have any effect. If you are still a young person, Yoboi, I think it is quite possible that you reach a time when you suffer the lies that you believed in that are fostered by the denial industry.We have all tried to show the the scientific evidence and you have repeatedly, and with full intent to do so, actively searched for every piece of psuedo-science you could find to post! I am through with trying to show you the scientific evidence that is readily available for all to see. Like they say, you can lead a horse to water, but you can't make it drink!Bye, Yoboi.Corrected spelling and grammar. .. Sorry,I was a bit rushed.

 Natural Variability Is Localn everygreen in denial land has been that natural variability covers all climate change. All of those econometrician types, and some of Eli's favorite crazy aunts are fond of this, but they are lumpers. There is no single natural variability. The tropics, of course, are the region with the most species, the most biodiversity, a hell of a lot of people, and an almost unchanging climate. Why do the bunnies think that the tropics have the most species, the most biodiversity and so many people? It is a lot easier dealing with a constant climate than one that varies all over the place. For one thing you don't have to change your fur with the seasons. The flip side is that nature in the tropics is not so well structured to deal with even small changes. While variability is low, human climate forcing driving the system beyond its usual local limit is dangerous. Of course, high latitudes are vulnerable exactly because climate variability there is so high. In that case one worries about damage that is hard to reverse from large excursions (things don't always break the way you want). If there is a really warm summer, and the permafrost goes really non perm, it's hard to dig the Alaska oil industry out of the muck. A paper to be published tomorrow in Nature The projected timing of climate departure from recent variability by Camilo Mora and friends at the University of Hawaii that makes an important contribution by recognizing this issue. Well, it does come from Hawaii, one of the places with the most constant climate on earth. They examined historic climate using 140 years of data for the past, and Earth System Models for the future (You want data from the future? Sorry, that is not currently available). They define exceeding natural variability at any position as exceeding the limits of the 140 year data record for various periods of time. For reference RCP45 is an emissions scenario that brings the CO2 mixing ratio in 2100 to 538 ppmVHere we present a new index of the year when the projected mean climate of a given location moves to a state continuously outside the bounds of historical variability under alternative greenhouse gas emissions scenarios. Using 1860 to 2005 as the historical period, this index has a global mean of 2069 (+18 years s.d.) for near-surface air temperature under an emissions stabilization scenario and2047 (+14 years s.d.)under a ‘business-as-usual’ scenario. Unprecedented climates will occur earliest in the tropics and among low-income countries, highlighting the vulnerability of global biodiversity and the limited governmental capacity to respond to the impacts of climate change. Our findings shed light on the urgency of mitigating greenhouse gas emissions if climates potentially harmful to biodiversity and society are to be prevented.The years when variability will be exceeded forever on an annual basis are shown in a) below, and on a monthly basis in b) below. Eli directs your attention to the summers in the Indian subcontinent and Southeast Asia.Mora et al., also looked at evaporation, transpiration, sensible heat flux, precipitation and surface pH of the oceans. he projected timing of the ocean’s climate departure was pushed forward to this decade when pH was considered alongside sea surface temperature. Global mean ocean pH moved outside its historical variability by 2008 (+3 years s.d.), regardless of the emissions scenario analysed.li wonders if Richard Tol would agree that this paper explicitly endorses the IPCC consensus?

 New video reports from Heligoland, the only really German high-sea island:Published by Deutsche Welle English, October 9, 2013Three huge wind farms are being set up 23 kilometers off the island of Heligoland -- in the middle of the North Sea. So Heligoland is undergoing a revamp: to become the world's "first offshore service island" and serve as a base for people involved in the construction and maintenance of the wind farms.Mayor Jörg Singer has invested heavily in the project and incurred debts: the expansion of the harbor alone is costing islanders 8 million euros. Many here say the money would be better invested in promoting tourism, Heligoland's main source of income for decades. Our series looks at the controversial changes taking place on the picturesque island of Heligoland.

Inhofe a speedy recovery & Thanking Modern Science for catching the problem early & undoubtedly saving his life!Hmmm... as a Senator he has great health care coverage (plus he gets paid during the shutdown).
