The Built World

Walking the streets in my now apparently abandoned neighborhood for an errand after a few weeks of sheltering in place in Oakland, I had the eery experience of navigating and inhabiting empty city. While I knew the pavement, I almost felt no longer familiar with the streets that afternoon. There was the sense that no one knew the state of affairs about reopening, and many were just puzzled about how to proceed: as a few young kids skateboarded up Shattuck Avenue, profiting from the lack of cars, some odd improvised bicyclists were on the sidewalk. The absence of interaction was a weird pause indeed, giving an eery sense of the timelessness of space, as if the time/space fabric by which I had long seen the neighborhood was suddenly out of whack. While no visible destruction had happened or occurred, the disembodied nature of the inhabited world was drained, even as it was filled with sunlight and birds, giving me the eery sense I had had when I looked at the machine-read maps of building footprints, “Every Building in the United States,” whose section situating Bay Area buildings hung on our refrigerator wall, like a scary map of the archeological ruins of a future Baedecker Guide to the ruins of San Francsico.

Had the designers of te interactive webmap of machine-readable imagery Microsoft had assembled intended the eery effect of describing the inhabited world as a ghostly ruin of lived life? The relegation to place-names to a very secondary status in the image of the overbuilt landscape seems to lie on the edges of the black blocks of built space that is was the basis for the AI map distilled from aerial photographs, and parsed as black and white data. If its form seems oddly ghostly, the reduction of the monochrome paper map reveals shades of grey that fade into rare open spaces, where one’s visual attention seems at first drawn, before one returns, with hopes for some sense of recognition, to the built spaces that one knows, and the congestion of black that marks urban agglomerations. The black boxes of settlement reveals the crowding of our coasts, the density of much urban housing and indeed of the area of the East Bay where I live, but is also an eerily image of an inhabited landscape selectively organized to omit any sign of living presence–either of “wilderness” or habitat, but anthropocentrically maps the anthropogenic world as if for posterity. For is not the black boxes of building footprints something like a record of the anthropogenic imprint on the world, by now extended across the globe. The building footprint map derived from AI is a rewriting of the ancient notion of the ecumene–the “habitable” more than “inhabited world”–or οἰκουμένη, which sought to encapsulate the inhabited regions as the ones that entered human comprehension: is it a removal of the humanist object of the map, now mediated through machine learning?

If the ancient geographers discussed the οἰκουμένη as the “habitable world” from the frozen north to the scalding sub-equatorial lands that seemed to “balance” the inhabited regions, as if what merited human attention and contemplation was that region that permitted settlement: the turn to a record of imperial administration in the Roman Empire–and of religious unity in a ‘civilized’ world–introduced the governmentality of the control over the inhabited world, that by the Renaissance had become an enticing image of national incorporation and political ties, that became intellectually articulated in the post-Cold War as a global ecumene of imperial cultural dominance and integration incarnated in European inheritance of political institutions, science, technology, and economic forms as a world system: the association of a global integration whose exponent in historical texts was perhaps William McNeill’s Rise of the West (1963) had withered away by the time of the data-driven map of inhabitation, as we have become increasingly aware of mapping the human impact on the world–an image in which the building footprint map might be placed.

It is hard to discuss intentions in a map that was organized by AI, but the ledger size newsprint that covered almost a full side of the refrigerator, hanging on magnets, assembled a flyover of the ruins of a future world, a snapshot of each and every building in the area. The result is a poor excuse for a “wall-map” of the region of Northern California. It seems more of a memento mori of the prosperity Silicon Valley once enjoyed from a future world, registering the intense economic growth that fueled the housing bubble along the San Francisco Bay, in an unintentional snapshot of the explosion of paved space and housing across the coastal margins of what was once one of the more “edgy” areas of the United States: entertaining the imagined future might have created the perverse pleasure of hanging it in my kitchen, long before COVID-19 struck, a celebratory if slightly morose record of the world in which we once lived.

But the sidewalks were empty and sun intense; storefronts often boarded up. The streets were no longer places for salutation or recognition, even if I greeted a familiar mailman on my way home: as if no time for social niceties remained I walked down the sidewalks and into empty streets, rarely negotiating margins of safety, or distancing with a few folks on foot, noticing with a cringe the large number of homeless who stood out against the stark streets, closed storefronts, and empty stores.

They were, as it were, always there. I had been cutting myself off from the surroundings, as I never thought I would. As I had been sheltering, thoughts going global as I was following updates about the pandemic, this was a stone’s through from my home, so many had none. Looking down Adeline Street, at the still tents of homeless encampments that may have multiplied, I felt new distance gaping between us, as the very streets I had walked down regularly seemed to have been forgotten while sheltering indoors, the stores now empty, their windows recently boarded, few driving in the streets where one might walk without danger. The eery absence of population was a scene from The Last Man, momentarily interrupted by an isolated airplane, the first seen in days, flew overhead: I felt like I was on a filmset, more than where I lived, a tracing of life past.

If we were sheltering, what was place, anyways?, I wondered with the footprint map in mind. Empty streets looked like nothing more than an apocalyptic reimagining of the neighborhood, drained of inhabitants, save the apparently increasing cluster of homeless tents, looking far more embattled, and more survivalist than ever. If the building footprint map was restricted to spaces where people lived and work, the ghostly anthropogenic substrate seemed to have an eery counterpart in the homeless encampments near my house. The survivalism was evident in the homeless settlement that had in recent years overflowed, expanding to fill in the island of trees where how Steve Gillman’s 2011 public sculpture marked the interurban divide. The public sculpture elegantly if snidely punned on the allegedly dismissive pity saying ascribed to an icon of modernity about her native home–“There’s no There there“–as an entertainment for motorists, or BART passengers, as much as a public art for pedestrian passersby–by broadcasting a literary reference in greenery.

The two words marked the Oakland-Berkeley border by two words, now rusted fifteen years later, as relics of an earlier epoch themselves: the homeless encampment blurred both sides of the dividing line between the cities which had long since melded indistinguishably in the increasingly gentrifying area where I had lived for twenty-odd years.

The erasure of a sense of “here” that was promoted by the public sculpture seemed erased in the AI map, that reduced space to built houses, even as the homeless were the only residents in sight as I walked around the tensely empty neighborhood. I’d long appreciated, if a bit begrudgingly, how the Gateway_Project defined the edge of Berkeley CA took Gertrude Stein’s saying and liberalized it in hight-foot tall powder-coated steel letters, where the BART tracks go underground, intended as “a literary and whimsical welcoming to Berkeley,” where they supposedly read not only Stein’s poetry, but where so many poets had lived–and was a “here” worth commemorating by sculptured letters, a new Fons et origo of the Beat Generation, perhaps, or a dynasty of mid-twentieth century poets–Kenneth Rexroth; Czeslaw Milosz; Allen Ginsberg; Gary Snyder; Frank Whalen; Thom Gunn; Robert Hass–by 2002 recognized as a literary patrimony. Designed primarily for passing motorists, as if few could be imagined to walk nearby, the site built to commemorate a “sense of place” had become a cluster of encampments, as if that was the only place that existed at a time when all remained shuttered indoors–if in 2010, just ten years ago, one letter was covered, by a group of Oakland knitters, to transform it to “HERE/HERE,” peacefully protesting the work as barely concealing an agenda of gentrification.

Jill Posener, on Jill Rants and Raves/June 1, 2010

The collective of knitters who had covered the “T” as if to object to the tired trope with which Oakland was long saddled was the result of a. relatively calm tussle, cast as a border war against gentrification. But the global pandemic had subsumed any distinction of “here” and “there” in a new global: the AI map seemed to be indeed a snapshot of the scale of habitation before the pandemic, a ghostly picture of an earlier time.

As I walked through it, at least, the same North Oakland neighborhood was suddenly, if maybe temporary, rendered ghostly: the built landscape that I was inhabiting was the same world, with fewer inhabitants, and less secure attachment to palce–as if the artificial interruption of indoors life shifted my relation to built space, made it harder to navigate, and shifted the security of place, and indeed removed any sense of recognizability from the built landscape, almost to ask what the civilization was that led to the building of all this paved space.

The unmooring from physical presence was like being dropped, I imagined in a flight of fantasy, to that Microsoft map, so akin as a snapshot to the sort of map of archeological ruins future generations might trace as guidelines of orientation to a lost past, when what was the greatest “here” of antiquity–the city of Rome–was etched by nineteenth century archeologists and antiquarians by the physical plant of what once stood on the site of the ancient Roman forum, only perceptible to the eyes of tourists if they had trained themselves on the map to imagine the ghost-like presence of architectural monuments that had once affirmed the place of Rome at the center of the world at a far earlier time.

Where was here, now, on the AI map? Was the tie I was drawing between the map and the uninhabited neighborhood only the depressive meanderings of a middle-aged crisis? Or was it a global one? West Berkeley and North Oakland had been certainly rendered quite a different place, quite suddenly, and not a comfortable one–still inhabited by ghosts. Stripped of my points of reference or familiarity with my neighborhood, a few dispossessed in the sidewalks, of what wasn’t a nice area of town, I was reminded rather urgently of ongoing part of urban life no longer framed by sounds of traffic, public transport, open businesses and pedestrian sounds, that continued while I was indoors. The degree zero of urban life reminded me of the empty landscape of building footprints that, in a detailed satellite overview that recalled nothing more than the outline of an archeological dig of ancient city, as if drained of motion, and filled with apprehension, in a damn eery way. Was this a pause or a new landscape?

I had only recently been navigating the 2018 building footprint map, “Every Building in the United States,” and aout a year ago, hung the section of the houses of the Bay Area onto our refrigerator wall. The creation of Microsoft that was removed as one might imagine from the ancient notion of an “inhabited world,” comprised of building outlines, a distanced description of the world a declination of mapping human settlements, mediated through what seemed the iconography of an archeological map of a removed time, rather than the actual lay of the land–or, better yet, it seemed to exist in two planes more than ever, and both as a historical record of a snapshot of built space across America, and of actuality. The interactive website of the machine-readable result of aerial imagery that invites one to zoom closely not on landscapes, but a black and white rendering of built space, recalled nothing more than a flyover of the ruins of a future world.

The aerial snapshot of each and every building in its current position had a sci-fi aspect of a record of space drained of nature, biodiversity, non-anthropogenic environments, and life–distilling selectively the extent of built spaces across an otherwise quiet and otherwise uninhabited world: as if the perfect document of the anthropocene, this was the built landscape, removed from and detached from a natural world. This was the built landscape of the region, divorced from the lay of the land, as if a perfection of the GPS contents of street view, without any street traffic or greenspace at all. The stark interactive map of 2018 seemed to be newly present to the space I was negotiating in my mind, even more stripped to its bare bones and evacuate of inhabitants.

The vertiginously uninhabited interactive map peered at onscreen allowed one to look at the nation and soon to whatever spot on the map, suddenly panning and focussing into crisp detail, but lacking all sign of inhabitants, save the names on each street or place. The sense of exploring a neighborhood I once knew may have been an accelerated arrival in late middle age. But the spatially empty landscape of building footprints encountered I opened in 2018, “Map of Every Building in the United States,”was filled with a sense of dread and of testing my own geographical knowledge, scanning to familiar neighborhoods and structure, and matching abilities to recognize the flattened forms against the material structures with which they correlate.  There is no sense of the amount of chemical waste and diesel pollutants in the nation’s largest port, Long Beach, pictured in the header to this post, where pollution has caused ongoing health problem for residents.

Mapping the Wobbliness of the Polar Vortex

Since we use the conventions of map making to endow solidity, or reify, even the most abstract ideas, it is interesting to examine how the ‘Polar Vortex’ has spread across the mass media as both a meme and icon of the current weather patterns of the new millennium.  Rather than map place by a matrix of fixed locations alone, maps of the Vortex offer a visualization of temperature variants that reveal an anomalous weather conditions that track the Vortex as it moves, intersecting with place, across the stratosphere into our own latitudes, tracking not only a “cold front” but, globally, the disruption of the path of the circumpolar winds, or splitting of the vortex from the north pole.  We are most likely to “see” the Vortex as an incursion into our own map, effectively dividing the country (yet again?) this summer into regions of cold and heat.  The currency of visualizations of the Vortex reveals not only a meme, but a model for encoding multi-causational weather maps.  Indeed, the mapping of the divergence from usual temperature range reveals the anomaly of a north-south weather front with the solidity of a national divide, raising deep questions of its forecast of extreme weather throughout the year more than offering something like a “poor man’s vortex.”

PolarVortex2

As the term has gained wide currency as a challenge within data visualization world for throwing weather systems into legible relief, it set a new bar for producing visualizations that are challenging to fully comprehend.  The Polar Vortex is mapped as it moves, as if on its own, across the stratosphere into our own latitudes, condensed in a range of data visualizations of stratospheric or tropospheric low-pressure fronts, in ways that map onto current quandaries of atmospheric and climactic imbalance.   The animated superimposition of weather patterns condensed in a range of data visualizations of stratospheric or tropospheric low-pressure fronts themselves map onto concerns about climate change, and conjure narratives of global atmospheric change and climactic imbalance:  the disruption of the usual harmony of the polar jet stream perhaps maps onto both notable rises in polar temperatures or torrential rains off the coast of Japan, but whether due to a spike in northern pacific offshore typhoons or openings in polar ice cover, the markedly increasing waviness of the vortex has allowed increased amounts of cooler air seep south once again, in an eery echo of last January’s mid-winter chill, that has lead weatherpersons to scramble for clarifying narratives about the return of that green blob.  (To be sure, back in January, the naysayers of climate change parsed weather maps as counter-evidence to global warming, allowing them to indulge in alternate meteorological realities, before they were batted down in two minutes by the President’s Science and Technology Advisor, Dr. John Holdren.)

Weatherman scrambling to gloss

twins-gfs

Offering a marvelous array of vowels and pattern of assonance, with a name befitting a Marvel comics super-hero as much as a weather pattern, the Vortex is a touchstone of climate change and a great case of how we have yet to ken the global as intersecting with the local.   But we have unfortunately trended to oscillate, as it were, in our maps between national weather maps, where the Vortex made such a splash as a newsworthy low-pressure pattern, to maps of patterns in global environmental change, that might better direct attention to changing meteorological realities.

Part of the problem is adopting a point of view on the weather that we are tracking–or of viewing the Vortex as a stratospheric phenomenon around the polar regions, or charting a weather pattern forecast as occurring within our nation’s bounds.  The reprise of the spill of northern air into the upper United States returned the Vortex into national news this July has provided a basis of the latter, to judge by this new visualization that projects the cooling temperatures in the northern United States, as a deep wave in the Jet Stream brought colder air to the Northeast.  Even if the cooling air that arrived was not arctic, the pattern of its arrival to the continental US this summer has prompted some significant debate among meteorologists who have glossed the map in alternate ways, almost entirely still focussing, oddly enough, in a reprise of the mid-January news blip on the Vortex, on the unit of weather in the United States in isolation from a global context.  The anomaly of the “Vortex” has become something of shorthand for a southern swing of cold air from north of the Great Lakes, produced by a decreased disparity between polar and sub-polar continental temperatures that lower the latitude of the jet stream, according to some research that has been endorsed by the National Academy of Sciences, and increased its waviness as the Arctic warms.  The maps serve to embody the increasingly newsworthy weather in the Northeast, reaching down to the southern states as if an invading army as much as a meteorological cold front, placing the anomaly of the displacement of cold air against the screen of an iconic national map on which it has been superimposed.

The map recalls a similar dispersion of circumpolar winds from the arctic into the lower forty-eight already called the “most upsetting” data visualization of the winter of 2014.  The drift of circumpolar winds at stratospheric levels offers a compelling means to understand the arrival into the Midwestern states of cold air once more from the north during the mid-summer of 2014.  Rather than only being a meme of the media, or being coined as a manifesto a group of avant-garde modernist meteorologists who found energy in the abstraction of weather forms, the term tracks the dispersion of the circumpolar whirl usually uniformly swirling about the pole offer both a rogue arrival into our national climate and a sort of emblem of an imbalance of circumpolar stratospheric harmony by pushing down the arrival of winds from the Pacific ocean.

The benefits of shifting iconography to the global are immediately apparent if only because they reveal the divergence of the weather system from a meteorological status quo.  The cycle of wind, usually located in the mid- to upper troposphere, has apparently begun to split or splinter from it usual centers above Baffin Island and Siberia as its air warms, and moves below the arctic regions.  The displaced vortex, which migrates below the arctic circle in the stratosphere, reflects the warming of temperatures at the poles, creating currents able to funnel the figurative migration of arctic air currents to sub-arctic latitudes, even if the air in question this July might more likely be northeast Pacific more than arctic in its provenance.

Displaced Vortex-full color windsEarth.com

The local is, however, far more easily digestible for viewers of The Weather Channel, and the Vortex is shown as an intersection of the global with the regional weather map.  Collating data from divergences or temperature anomalies from a database covering local temperatures in 1981-2010, the spectrum of a “heat map” tracks currents of cold across the backdrop of the lower forty-eight in an easily digestible manner that packed so big a punch for folks trying to puzzle over the freezing over of roads, local lakes, or back yards:

Vortex in States

Once more thrown off-balance, it sends cooler air below the lower forty eight and forty-ninth parallel, making it national news as a dramatic aberration that marked the entry of intense cold.  Data visualizations provide new tools of making the meteorological concept legible in ways that gain sudden particular relevance for audiences familiar with weather maps, for whom immediately powerful associations of shifts in the measurements of regional temperatures will pop out at viewers of a forecast or weather map, forcing them to pay attention to the meteorological imbalances they portend.

Recent global maps of the Polar Vortex offer more than an icon of the transcendence of territorial boundary lines systems, by processing and portraying the Vortex as an expansion and  breaking off of cold air outside the restraints of an arctic air system.

November2013_polar_vortex_geopotentialheight_mean_Large

The dramatic splitting of the arctic jet, due to atmospheric pressure anomalies, was mapped by NOAA in this data visualization of July 2014, of a splintering of the vortex, in apparent response to the warming of our poles, hastened by the diminishing snowfall and ice-cover that create new chilly islands or microclimates on the ends of a warming pole we often seen as lying so far away:

July Polar Vortex 2014

The disruption that results brings the displacement of arctic winds that most often sit anchored around the polar region.  A “weak” polar vortex, interacting with arctic ice-cover decline and reduced snow cover, was some time go modeled as resulting in a meandering arctic jet stream and occasional detachment of a polar weather systems and consequent decline or weakening of pressure gradients of the vortex, and consequent reconfiguration of the arctic jet stream:

N_Jetstream_Rossby_Waves_N

Has something like this occurred?  The dynamic visualization of weather maps in five colors and striking contour lines provide clear tools to visualize its speed and energy, in ways that might even have helped resurrect a term that had languished in meteorological lexicons from at least 1853, when the “continued circular gale” was described as flying “more rapidly and more obliquely . . . carried upward to the regions of the atmosphere above,” as lying in the ambitions of a “great Air Map” but based on the recent 1851 NOAA mapping of “great undulatory beds of the oceans . . . for all practical purposes of navigation.”

great polar vortex

But now we have a recognizable image that can be tracked over a recognizable terrestrial map that concretizes the Vortex in ways that its winds can be understood as extending over a region of truly global expanse.

Tracked in terms of actual temperature anomalies, in the winter of 2014, when newscasters and NOAA (the same agency) mapped the migration of cold air southwards of the pole into our frontiers, far outside the usual path of the jet stream, in a disturbance of the weather systems worthy of national news last January, in a data visualization which tracked a green (or purple) blob whose forced migration of frigid air from the polar regions that disrupted weather patterns with national consequence as it migrated out of Canadian airspace.

Vortex in States

In the dramatically eye-catching graphics of television’s mass-media, as the bulge of purple and magenta of detached low-pressure systems migrate south, crossing the very same borders to which we are increasingly sensitized in our national news media, albeit at tropospheric altitudes no fence or border guards could ever patrol.  Indeed, the map suddenly suggests the increasing vulnerability of our delicate weather systems, echoed by the language with which the Polar Vortex’s “EXTREME COLD” loops invasively southward across our northern border, cutting off Pacific Air:

650x366_01161627_hd31-1

650x366_01161752_hd30-2AccuWeather

The apparent incursion of its jet stream into the bounds of our national airspace, as in this image of cold air migrating across the northern border, results in the proliferation of metaphors all too often violent in tone:  Climate Central may have only adopted the robust rhetoric of sportscasters when it described high pressure systems in quite athletic terms that “block the eastward progression of weather systems, like an offensive lineman protecting the quarterback from the other team,” allowing the air that circulates around the arctic to start “spreading tentacles of cold southward into Europe, Asia, and North America.”  Less dynamically interpreted and understood once cast in global terms, rising temperatures at the poles–the very sites where, we should note, global warming is occurring at a rate twice the global average–displaces the previously concentrated flow of a jet stream of cold air from its arctic abode.

Of course, few seem ready to tie this to the diminishing ice-cover of the north pole, which still seem a leap too far to be made logically. Oddly, the meteorological mechanics of the expanding split-off of polar winds is modeled as an incursion of weather patterns echo the metaphorics of a military situation map of fixed borders, a historic hold-over for national weather organizations like NOAA:  the global image of wind velocities around the pole, depicted below, is oddly absent from what is actually a global phenomenon.

polar-wind-displaced-vortex-2-1-14Earth.net

But we are all too used to interpret and read weather maps with both a sense of voyeurism for our friends and relatives, but from a subjective lens.Despite the adoption of globalized images from our friends at National Geographic, who used Mass FX Media’s animation to visualize circumpolar air flows, and despite the continued live monitoring of wind-flows at “Earth,” the isolation of the nation in the maws of the vortex is so readily discussed as the “most upsetting map of the winter,” as if the migration of the pool of arctic air into the northern United States were best understood as a disturbance of national temperatures.

The similar narrative about the Vortex in national forecasts stands in contrast to the maps of rising temperatures, but create a visual modeling of a meteorological distribution that almost resembles an invasion.  Even though the distribution and speed of the Vortex in summer is usually slow, the polar air however seems to be arriving from across the border with unstoppable velocity, the below global visualization, also based on a similar distribution of deviations from average temperatures craft a similarly compelling large-scale weather pattern–albeit one occurring some 3,000 feet above the earth’s surface–in which, rather than reveal a lack of equilibrium, arctic air dips south across the forty-ninth parallel and past the Mason-Dixon line, confirming its occurrence as a shift of national consequence.

19g70jjap4syugif

Because the “most upsetting map of the winter” tracks the pooling of arctic air into the northern United States created a disturbance of national temperatures into the Eastern United States and much of the central region of the country.

Wasn’t it once more reassuring to understand the polar regions, its topography unknown, as somehow removed from the atmospheric currents than being mapped around the world?

UNEXPLORED POLAR BLUE

The wonderfully protean animated map of disequilibria in the harmony of stratospheric currents of cold polar air within the jet stream opens breaches across national boundaries, albeit at considerable elevation, and also offers a way of tugging at one atmospheric phenomenon to unpack a web of inter-related phenomena.  Unlike maps of habitation or land-surface, the map traces a low-pressure system at high altitudes far above the settled or occupied land, but intersecting with it in ways that conjure a failed ability to contain colder air over the polar regions.  (Taking the iconography of weather maps as transparent, the blogosphere has suggested the adoption of charges of circumpolar intoxication.)

The distribution of stratospheric air whose flow is charted in global map as an irregular anomaly of temperatures’ spread, is perhaps most concretely rendered by the iced-over bodies of water it left in our own upper latitudes.  The striking freezing over of the Great Lakes, covering some 88% of the lakes’ surface area by mid-February, a greater proportion of seasonal ice-cover than ever registered, and surpassing the 82% record of 1996, according to Caitlin Kennedy of NOAA, which render the striking concentration of ice in frozen lakes a concrete map of the local effects of truly polar weather.

GreatLakesIce_610-1

The material manifestation of the cold on the surfaces of those five lakes–all frozen solid, to appearances, save Lake Ontario, seem as concrete a result of the consequences of climactic change one might have in a chart, by placing the ice-covered lakes in a local landscape.

What seemed the displacement of the frigid polar air to the Great Lakes became something like a confusion of the local and the global in the news media that was played out in weather maps.  Of course, the meteorological mapping of this winter’s Polar Vortex in Canadian outlets seemed more the status quo, with most of the country facing sub-zero temperatures:

640x480_currents_ca_temperature_i1

The US “low temperature map” used a slightly different temperature spectrum, but preserved a more alarmist image of anomalous weather conditions even in the National Digital Forecast:

The striking visual by far was from a site located exactly on the US-Canada border, an  eye-catching a frozen Niagara Falls, that icon of liminality:

52d0f434d39a1-1024x614

The distributions that charting the mid-July summer chill newly arrived in the Midwest and much of the East coast of the United States from Canada is less striking, even if it will bring dips of twenty to thirty degrees form the normal.  NOAA omits Canada completely from its prognostications of the arrival of the coming cold, as befits its role as a national agency, and restricts its purview to United States coastal territories, even though it would make the graphic far more credible to offer a greater coverage.  It provides something of a summertime counterpart, however, in which the probability of lower temperatures than usual seem to create a ring about the same lakes, radiating almost to the Atlantic coast:

NOAA POLAR VORTEX

Where is the center of this new system of cold air? With roots in Hudson Bay–where else?–the polar air will be spinning southwards at the upper levels of the atmosphere, spinning southwards toward the United States. There were past migrations of arctic air over Quebec and Maine, back in late January, 1985:

Polarvortexjan211985

The Detroit Free Press even seized on a recent NOAA projection of a similar displacement of arctic air, that locates the center of cool air migrated toward Michigan, forming a pool of air that had descended into the central United States, as if to cast the event as something like local news, even as it suggests the rise of two weather systems:

safe_image.php

The occurrence isn’t strictly polar, or arctic, in its origin.

But the results are the consequence of a sort of distorting decentralization of the polar cold air outbreak that hovers around the arctic circle, running around the pole and allowing or protecting cold air from drifting south, containing cold air or not it its high altitude low-pressure system.  (Of course, the west coast is poised for a dryer and hotter-than-normal week.)  The decline of snow and ice around the Pole, combined with the warming of the wobbly gulf stream, will allow the chilly polar air to spill southwards to the plain states, covering not only Canada but spilling outside the low-pressure system and over to the seaboard, in a sort of nervous breakdown of meteorological model behaviors.

The disturbances of equilibria in our weather maps makes it worthy of more than symbolic note. The increasing variability that the waviness of the outer line of the low-pressure system, or jet stream, related to the declining snow cover in the far north, in the a “warm Arctic-cold continents” pattern, where the compact containment of colder airs was broadly breached.

Jan5_Nov14-16_500mb_geopotentialheight_mean_620

The lack of equilibrium in the stream of polar winds–distinct from the widening polar ozone hole–opens up more of the terrestrial surface to chilling shifts in temperature. As much as the embodying a low-pressure system, the map is a narrative of the disruption of climactic harmony, and view toward the future of weather systems world-wide.  The results of the wavy polar vortex, joined with rising world temperatures, create a map of bizarre spottiness in average world temperatures that is difficult to conceive or map, precisely because its high-altitude distribution is difficult to transfer from a spherical to a flat surface, and because its distribution unfairly privileges the tracking of cold air in ways that seem, misleadingly, to fly in the face of the maps of our overheating world.  This past January, NOAA crafted a digital globe that displayed the distortion of local temperatures distorted beyond the norm, with cold displaced from its polar resting place, resulting in a cognitively useful modeling of a disjointed jigsaw of cold and warm air, where the warmer deviations of global temperatures spick not only over western Russia and Alaska, but at the polar regions itself.

polarvortex_airtempanom_610NOAA Climate.gov

The result is a jigsaw reveals the breaching of cold air from the cap of winds that encircle the polar cap has a enough of touch of biomomorphism to echo ecofeminism; the forcing of warmer air patterns resembles a blurry sonar image of curled-up embryonic twins resting in a womb as if evoking the shape of future weather systems, offering a biomorphic visual metaphor for something like an eery augur of a future holding limited possibilities for an afterlife–and of the unknown future of our planet’s atmosphere.
