A much warmer Arctic:visual proof

   

December 19 2016 NOAA HRPT (darker),  December 18 1987 USSR Meteor IR.   Huge differences starting with surface temperatures,  a good +10 C warmer in 2016,  plus numerous features of wider open water.


 

GONE: #1 Famous ice bridge between Canada and Greenland,  a documented 

historical location used by Inuit dog teams likely for Centuries   Part of an ancient migrating route going back millennia #2  almost completely frozen Nares Srait.

#3 NE Ellesmere NW Greenland steady ice sheet,  virtually always surviving the summer.  

#4  The Big Lead,  a phenomena requiring very consolidated sea ice,  strongly frozen together mainly by very thick sea ice.  #5 Tidal leads.,  closely linked to tidal waves during greater tidal height variations.  They froze easily and disappeared quickly by drifting snow.  #6 Ice next to Spitsbergen, 

a mere small portion of the huge habitat dwelled by Polar Bears .  #7 Smith Sound Polynya  narrowing, a very important wildlife zone for Belugas, Narwhals, some sea birds and Bowhead whales.   Vaster ice span gradually push wildlife to a narrow area always open despite coldest weather possible.   Lately many whales get trapped by later refreeze of sea ice. 

NEW:   #1 Beaufort sea open very late in Darkness.  #2 very open Smith Sound,   #3 Thin sea ice leads radically not symmetric to tidal waves #4  Big lead not showing at all.  #5 narrow Straits much more open along with very thin ice very dangerous to walk on.  

A strict numerical sea ice extent interpretation may suggest  less change between the pictures presented separated by 30 years,  but there is much more than enunciated above,   the biggest one is clouds,  looking carefully at 1987, we see clouds barely surviving the very cold dryer environment.   These clouds lazily hung out with very little injection of moisture from the Northern oceans.    Winter was really set,  called "mid-winter" for a reason.   WD December 19, 2016 

Polar vortex spin off vortices, North Pole Cold Temperatures are Southwards well away from the Pole

~Polar vortex is the entire spinning of the Polar lower troposphere like a cyclone
~Vortices created within, sometimes one , two 3 or 4. Move about.

"A polar vortex is an upper level low-pressure area, that lies near the Earth's pole. There are two polar vortices in the Earth's atmosphere, which overlie the North, " Wikipedia

Not only 2,   there can be many vortices. This article from science alert is very good:

http://www.sciencealert.com/it-s-official-the-polar-vortex-is-back-with-a-vengeance

When there is an incursion of warmth towards the Arctic Ocean, like at the moment the vortices are pushed Southwards:



Northwards of Green delimited zone is the Polar Vortex of the entire Northern Hemisphere as expressed by NOAA 500 mb heights map December 15, 2016. Consisting of 3 vortices centers in dark purple, note to the right of each smaller vortex there is a Northward flow of air, to the left a Southward flow, yes it is cold in North America  however very opposite warm NW Europe. When a TV meteorological presenter says the "Polar Vortex" is back, he or she means a single smaller vortex part of of the entire Polar Vortex system. There is apparently no single word for 'vortice', hence the confusion of using Polar Vortex. Another way of presenting the case would be to say that the Polar Vortex is weaker, hence less circular, oblong and segmented by severe warming near or towards the North Pole. A single segmented vortex usually wraps the jet stream stream around it:



December 16 2016 CMC 250 mb chart. Blue trace my own. Within the blue trace is the center of vortices, there lies a surprise, it is the Cold Temperature North Poles. The coldest air possible.



CMC 500 mb chart December 16,2016. Although ideally the temperature of the entire troposphere is found by a 600 mb chart (they are rare,  can't find). We can clearly read -51 C close to Great Whale river Northern Quebec,  this is the center of the coldest air in the Northern Hemisphere,  note Ellesmere 1500 miles North, -30 C.    At center of CTNP the winds are weak to none, similar to center of hurricane but on a mega monster scale.

It may said that it is colder further South than the Arctic, these are the days when winter builds up over the continents, the Arctic Ocean atmosphere being much warmer affects the weather every where Southwards,  the term Polar Vortex should be explained more correctly because this implies a Colder very expansive Polar region,  in fact its warmer at the North Pole devoid of any sun light whatsoever.WD December 16,2016

Dramatic Arctic Warming captured with ice extent and temperatures: Area under the DMI 80 temperature curve biggest in 2016 in direct relation to substantial daily open water area.

Average Arctic Ocean surface temperatures have a close relation to either sea ice or open water total areas.  

These three measurable geophysical parameters are inseparable,  they cause and effect each other to vary.   The easiest one to immediately visualize is open water,  dark, but warm especially in winter.

Sea ice extent variations by Cryosphere Today depict a steady
downward trend,  except of course for 2016 with numeric data calculation problems.
Obviously absent sea ice is replaced by open sea water.   The large 2007 and 2012 variations depicted above are largely due to favorable melt or compaction conditions as caused by Arctic Dipoles or rather large Cyclones mixing sea ice with already open water huge sea waves.  

    Visualize the graph year by year,  mentally calculate the area under the red curve with respect to green,  I calculate every year above 0 except for 2004.      

The period of greater demise for Arctic sea ice started in 1998,  if we integrate the space under the DMI 80 N temperature red curve vs average in green,  we may get a correlation with respect to open water extent.  Note 2013 the last year with expansive sea ice after minima, the red closely hugged the green more often.  Note the years 2016, 2012, 2007 and 2006 being particularly ocean blue with a largest integrated temperature areas matching open water extent  or are very well reversely proportional with their lowest sea ice extents.  2004 temperature area integration is close to 0 which coincides with 2004 ice extent being pretty average.   The pre 1998 curves appear to have a consistent integration much closer to 0 or less:

      The integration of the space under the red DMI temperature curve with respect to the average should be close to or below  zero for every pre 1998 year,  considering when temperature is below average the calculated area is negative.

        What we may conclude from these mental integrations: there's a hard road back to normalcy for sea ice to rebuild,   if not an irreversible downward extent trend particularly demonstrated by a very large,  the largest under temperature curve integrated area in 2016,  indicating much more open sea water,  it is exceptionally foreboding.  WD December 13, 2016

From warm year to warmer: A different icescape world in 5 years

Sea ice greatest feature is the recent memory it encapsulates,  it is planet Earth's graph  displaying not only daily but more monthly/yearly trends:

  2011 December 6 (darker),  2106 December 9 NOAA IR North Pole captures.   2011 has very long tidal leads, despite a warm winter then,  these occur mainly during Lunar events sometimes in combination with winds.   A sign of sea ice consolidation,  a more congealed cohesive sea ice pack.
2016 has Myriads of very small leads interspersing countless thinner broken up sea ice pans.  A much more fluid ice pack,  not really amenable for mega lead formations.   The more frozen areas of 2016 pack has some much smaller mega leads.  We are very close to winter solstice, if this badly broken up sea ice pack continues till Maxima date,  2017 summer sea ice prospects look very bleak.  The badly broken up sea ice state is deeply intertwined with a feedback loop enticing Cyclones to persist over the long night Arctic Ocean, these keep the sea ice from accreting normally,  keeping the pack loose.   This long night may be the starting time when sea ice extent variations simply will stay down year round.

The "Perfect Storm" 1 month late minus the hurricane merge

"Here we are in the graze of winter"

John Mellencamp

  Once upon a time,  there was a season for scary combinations of weather systems merging,
the time was October 31 1991:

       Winter's moved in,  what they call an "Arctic blast",  changed the configuration of the entire North American weather map.    Very bitter cold.  This in part created the Perfect Storm of Andrea Gale fame, ode to the fishermen of NE coast who braved it.  

     2016 has same winter blast,  much weaker,  is a coming 40 days late:

ECMWF  portrays coming High pressure "Arctic dome"  originating mainly from Alaska,

a pale shadow of former self, while the Arctic Ocean is currently dominated by a Cyclone which just  kicked out a budding mega cold "dome" forming,  the by-continental merge of cold air zones was cut in two,  leaving Alaskan build up to come down the Rockies path.  However, on the East coast of North America,  a huge Cyclone system will blossom December 9-10 not unlike segments of the Perfect Storm of 91,   but minus Hurricane Merge,  December  being well past hurricane season,  the last one Nicole streamed by Mid-October 2016. 

       Fortunate merge-less system unlike in 1991,  when winter was winter, long lasting and coming early each October, now we have  a different world, again all facing a warming,  all regions bracing for different weather.  Unknown combinations await.  WD December 5,2016

  Last 30 days (from December 7) NOAA temperature anomaly.  North America is not as cold as old November's use to be.

   We have an "Alaskan Cold Dome" slowly moving South,  looking very similar to the 1991 chart above,  40 days late from the Perfect storm date.  Winter is starting late.   CMC 0600 UTC 12/08/2016.   WD  December 8, 2016.

Late one sided winter start, example of what thick sea ice did regularly months earlier, and what happens later when less sea ice is looser pack

We follow here the progression or regression of the first dominant Anticyclone to cover the Arctic Ocean.  In the Past , Siberian cold continental air easily invaded  and teamed up with the other side 

of the world cold dark clear air massive buildups,  the beginning of cold dark winter didn't take long to be felt by millions once they merged.  Now we see first hand the further demise of  early winter:

 CMC Surface analysis November 25 18:00 UTC,  November 26 00, 06 and 1200.   With real cold air in Siberia, normal -45 C, but warmer every where else in the Arctic.  Some North Atlantic Cyclones now repulsed towards and warming the Urals, this was the settled view for years starting in October.    We now have a push block situation,  the Pacific Cyclone is pushing Northwards,  the latest North Atlantic Cyclone blocked and stalling towards Greenland.
For weeks,  there was no wide spanning Highs over the Arctic Ocean.  Now we can surmise the numerous leads amongst thinner sea ice finally freezing.  I watch carefully how strong or enforced this North Pole High will be.  The cold gathered in Siberian darkness wages the spread of winter from darker lands favoring radiation to space.  In Northern Canada,  the Pacific and Atlantic Cyclones continue the warmth initiated by the great sea ice dispersion event of early September just past. WD November 26,2016

   Next day November 27  show a retreat of the High whence it came,  back positioning because Cyclones have influenced the jet stream favoring their return to the Arctic Ocean,  made easier by the warmth still present,  the jet stream is bent along the Eastern Greenlandic line easing the return of North Atlantic Cyclones.WD November 28,2016

   November 28 key Cyclone position Northeast Greenland is a slingshot for the next one to the South, North Pacific Cyclone conspires to do the same,  the Siberian High is much thinned but still resisting the perimeter assault.WD November 29 2016

November 29 Push and Pull is in,   the Cyclone NW of Canadian Archipelago coast has severely weakened the Siberian High,  all while partner from the North Atlantic did the same.    Not really apparent,  the High pressure SE of Greenland has injected tremendous heat Northwards abetting
the push to destroy the Siberian Antiyclone.  Again the Cyclones have hanged about Arctic Ocean locations which warmed the most over summer past.  Coup de grace is about to finish the Siberian cold,  the NW archipelago Low will pull in the Atlantic Low ,  soon the entire Arctic Ocean will be back to clouds and Low pressure warmth.  WDNov30,2016

  Gone, the once proud High pressure zone spanning the entirety of the Arctic Ocean vanished Day November 30.  Ever present Arctic heat has encouraged warm air Advection not only from the seas,  but from Northern Canada.   This is quite unusual,  even 2012 had no such event in Early December darkness.   The temperatures of the entire Troposphere in 2012-13-14 -15 spanned much colder all over the long night.  Americans and Canadians don't know yet how warm this winter is setting up to be.  But they already have had a very warm start of winter,  no sign of industrial planetary sized cold air production even in Eurasia.  Every location is geo-meteorologically linked.  Here again suggests warmest influence from the oceans.  WD December1,2016

Unprecedented Arctic Ocean surface Air warming and computer modeling, are they integrating the sea ice current morphology?

First the unprecedented warming bit.   Autumn early winter 2016 outclasses all others.  DMI North of 80 surface temperature s easily beat 1998, 2007 and 2012 by very wide margins.

We should apparently use this model to predict the next season minima with 66% confidence:

Fall 2011 DMI really didn't give a hint of the coming 2012 summer season melt. 2006 fared quite well,  2015 not so bad.   

ECMWF 500mb animation,  next 7 days along with 2 other models,  GFS and CMC ,  all agree that the incoming Cyclones from the North Atlantic will not happen.  Note the lack of steady position of the 500 mb Lowest thickness.   500 mb  is used here to find the coldest column of air about .    If the 500 mb lowest height was around Southern Greenland,  there would be great flow Northwards.  

CMC surface analysis November 24 1800 UTC,  Culmination of a High mainly built from the Southern Siberia which had -40 C a couple of days ago.    The battle is on,  will the incursion of Cyclones to Pole stopped?  The temperatures at such places as Franz Josef and Spitsbergen are very invitingly warm.  Sea water temperatures of the North Atlantic  are still very High,  over the sea ice,  clouds but clouds despite the 1033 mb High.  Let's see if the great dispersion of sea ice, at  minima 2016,  has finally its impact faded to more normal icescape weather.  WD November 24,2016

Arctic Ocean air in total darkness enormous warmth, even in clear skies with partial North Atlantic air advection.

~Only one thing does that: ocean heat.

CMC Nov 21,  1800 UTC,  Surface Analysis.  Total darkness, varied in location -4 C to -20 C Arctic Ocean temperatures are extremely warm as a whole.  In particular Buoy 48276 ,  -12 C 85 N 90 W,  a place where -30 C is common at this time of the year.    What we see there is a great number of leads, where once was the densest thickest sea ice,  the engine that spurred winter to roar is now mainly  cooled from the South,  the only advection there is cold from land.    The 1024 mb High is not conducive to warming in darkness as well.  The only thing left is the warming from thinner sea ice and these leads,  which under clouds, or making clouds, keep the surface air on top of sea ice warm.

 NOAA HRPT November 21 1500-2200 UTC IR animation.     The warmest air as seen on surface analysis was below denser clouds,  but the open air has absolutely no other heat source but from the Ocean.

          2016 November great Arctic Ocean anomaly is a "dry run" of what an open long night Arctic Ocean would look like.  Cooling in Darkness would take place over Canadian Islands and Greenland,  this bends the Jet Stream Northwards on the East side of Greenland,  effectively driving warm air Cyclones to the North Pole.     In today's current situation,  multiple leads amongst thinner sea ice don't freeze over as rapidly compared with vast extent of older much thicker ice causing deeper quicker freezing and the build up of Anticyclones.  The current flow from the North Atlantic  slows the onset of a normal winter considerably.   The new presence of multiple leads dispersed throughout the Arctic Ocean,  as opposed to in parts as during previous recent warm years,  is similar to a wide open Arctic Ocean,  much tamer now,  but driving the circulation to keep the leads open,  or in the future, to maintain sea water wide open.  WD November 21, 2016  

Dispersed, emaciated, heat diminished sea ice barely holding together as once upon a time. 1988

28 years ago,  Mid-November 1988,  sea ice was fierce,  consolidated,  encouraged the build up of winter.  Its ice was expansive ,  all the way to Spitzbergen,  North of Ellesmere it was the world
of the big lead,  a lunar phased tidal break up,  it was also the time of the famous ring barrier,  a cousin of the big lead,  between Northern most Ellesmere and North-Western.     1988 IR picture above was bitter cold white,  signifying a normal -30 C or colder.  2016 note day after , November 18,shows the ravages from a warmed planet.  The Big Lead does not form because sea ice is extremely de-consolidated.  One Japanese North Pole expedition the following year,  was on ice, just off Ellesmere,  a huge sound was heard by all,  like thunder for hours,  very scary noise.  It was the Big Lead,  opening,  freezing and closing up again within 2 days.  The well equipped expedition shortly thereafter encountered a wall of broken up sea ice shingles, 10 meters above the ice plane, 1 Kilometer wide along the course of the coast for as long as eyes can see.  It took them 1 week
to get through the big lead wall,  1 kilometer a week speed.    2016 offers no such icescape.

    November 17 1988 IR NOAA capture,  note sea ice temperature as white as the land features.  Meaning ,  winter was normally huge,  spread out From Russia to Canada.  A completely different world of weather.

November 18, 2016,    whatever is cold is over Ellesmere and Greenland,  with very little sea ice freezing as much as 1988.  Cyclones dominate the Arctic Ocean.  Spitzbergen is surrounded by open water,  the strait between Northern Ellesmere and Greenland has loose pack ice,  no tidal ring forming.  WD Novenber 19,2016.

2016 Warmest mid-November Troposphere

  Day November 14 ,  2012 through 2016,  a snapshot in time at 600 mb (close to the average temperature of the entire troposphere).  2016 easily exceeds 2012 in warmth,  note where the
densest sea ice should be,  North of the Canadian Arctic Archipelago,  2016 warmest by 10 to 12 C.
It is an undeniable reflection of the state of sea ice,  swamped by mainly Atlantic cyclones,  which have dramatically slowed the refreeze,  but a stronger presence of thicker sea ice with less leads do the opposite,  repulse Cyclones.

  The year  for Nov 14 with the lowest expansive Arctic Ocean Pressure was again by far  2016.
