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.

Dark Horizons, latest cutting edge refraction analysis

~ New equipment allows to capture horizon with sun as low as  -11 degrees below A.H.
~Very latest data suggests 2016 has exceedingly thin sea ice.

        A series of observations on the ground and within the air itself may help explain surface based thermal inversions,  of which a significant player is sea ice and snow cover.

        Darkness offers ideal thermal flux studies,  largely because inconsistent rapid changes by clouds and sun radiation from varying elevations can change the thermal balance quickly.  Without the sun,  we can literally see how thick sea ice is because the only heat source is mostly from the Ocean even if covered by ice and snow insulation.    If sea ice is thinner,  more heat escapes from  it by conduction, convection and IR rays.   But the very top of sea ice surface can have the same temperature but was never observed warmer than surface air,  triggering a prime optical refraction rule: - top of sea ice is always colder or equal in temperature to surface air- ,  as observed in all observation captures so far,  this is just as so in darkness as well.

     It is also known that the upper air temperature profile maximum point increases in altitude in direct proportion to how cold the lower atmosphere is.  The higher the warmest air layer  altitude is on a given upper air profile, the lesser it can influence the surface temperature below,  the steeper the surface based inversion usually becomes, in optical response the horizon rises.    Warmer oceans than air right above always cause the surface to air interface to be adiabatic,  freezing of sea ice surface marks the beginning of a different lower atmospheric profile,  isothermal at first,  then progressively after, surface based inversions start to dominate and eventually persist all winter  except for advection from long night Cyclonic intrusions.
 

November 11 2015 (darker image),  had about 1 arc minute higher horizon elevation compared to 2016 November 15.    As such,  Nov 2016 had warmer temperature -20.3 than 2015 -24.5 C.  Photo captures were done with older telescope (darker image) and more powerful  newer telescope (brighter image).    So far, all comparisons with previous years in brighter very early February captures suggest a very thin sea ice at present.  WD (Nov 15,2016).     

Creeping Northwards winter faces the new world order of open water

~The fight is on,  but Darkness will make winter win.

   18 z CMC Nov12 2016,  the flow of warmed air over open water meets the coldest of this winter yet from Siberia.    There has to be cooling in darkness, especially over land areas.   And so it happened.  In the not so distant past the Arctic Ocean the Arctic Ocean was solid frozen at this moment,  winter easily spread Northwards making a much more fierce winter core for the rest of the Northern Hemisphere.     Now winter gets isolated,  its basic macro geometry has changed.

  1045 mb High with temperatures as cold as -36 C meets the ice free Oceans,  but its the one from the North which shapes or stalls it.  Up to 15 degrees or more warming.  Bending and shaping the anticyclone.   On a wider planetary scale,   the climate is altered significantly from a past which wouldn't have this open water at all.  Again as of last decade or so,  winter has started within the Northern Continents,  as so, within the last dozen years,  all kinds of strange weather came about,  this year will be weirder because the causation from lesser thinner sea ice is bigger than ever.

Not enough North Pole Old multiyear sea ice to make Arctic Siberia normally bitter cold

  Imagine a parcel of air moving like a box on a very long transpolar conveyor belt 2 meters above sea and ice.  In the box there is a thermometer.   This is how we can judge how effective sea ice is in cooling warm air coming from the very warm North Atlantic:

CMC 12 UTC November 6, 2016 surface analysis.  Demonstrates a meek cooling over sea ice of about 14 C over a very long distance by way of the North Pole (1200 Nautical Miles).  Then after,  the remaining Pacific sector open water warms the parcel more than +12 C.  Rendering Northeastern Siberia unusually warmer  than Central Siberia,  where winter has started in full.

Astounding Dark Arctic Night heat

    The main feature of the last 2 days was abnormally warm Arctic Ocean surface temperatures.    But look further at this NOAA animation capture.   There is a lot of clear air in complete darkness,  not that clear air is totally moisture free:

    Closer to 0 kg of precipitable water per meter square, over the greater Arctic appears to be quite normal;

     The Arctic +5.91 C anomaly is dwarfed 3 times by the Arctic Ocean surface air anomaly,  yet again without a complete massive cloud cover in total darkness.   This leaves mainly one source,
the Arctic Ocean itself,  it means that there is a supply of steady heat from a badly broken up sea ice very slowly consolidating to new ice the multiple thousands of heat giving water leads seen above.WD

Big Lead story..... It is not there...... Instead we see a great deal of fracturing as expected from a much warmer October Arctic Ocean.

   October 27 2016 NOAA IR HRPT Northern Ellesmere Island Canada.  Finally a clearing after more than a month of clouds.  The densest sea ice of the Arctic world appeared de-compacted,  disassembled by a massive dispersion event,  looked more like new ice just freezing interlaced with thousands of leads.    Speaking of which,  the Big Lead footprint is glaringly absent,  it may last for weeks after it opens, but not much of a sign of it here.  This is clear evidence of laterally decompressed sea ice.  The big lead is a construct of very dense sea ice, it occurs during the coldest days of winter as well as summer,  what is needed for it to show is a strong Tidal event.  Usually during the full or new moon periods.  This picture was taken during a near new moon phase.  Of interest is also Kennedy Channel,  clogged with broken up sea ice flowing with the Tidal driven current.

    NOAA HRPT IR  with different darkness setting than above,  November 13 2012.  2012 densest sea ice then was much more consolidated,  fracturing a whole lot less,  there was some CAA open water shoreline open water that froze (bottom left),  but the big lead(s) was prominent,  a sure sign of stronger compaction .  Kennedy Channel was much more open,  again a sign of a stronger consolidated pack.

         What we have just observed  was the result of a complex chain of events which essentially rendered early winter densest pack ice much weaker, laced thousands of leads giving away heat enough to foster lingering Cyclones to keep the Arctic Ocean mostly covered with clouds.  A few days ago, the coldest air was from the center of Canadian Arctic Archipelago,  and lesser over Northeast Russia merged. Just before, EX Hurricane Nicole pushed a segment of the North Atlantic jet stream deep towards the North Pole,  to the South of the stream was an Anticyclone which helped consolidate Higher pressure over Center of Arctic Ocean making join the 2 coldest air zones from the continents.

        We now see how bad the densest sea ice is,  in effect a broken up shadow of its former self,  a collage of thousands of pieces just freezing together at this time.  Sea ice dynamics are now drastically different.  Expect the unexpected from this time onwards.  WD October 28, 2016.

Remnants of a Hurricane Nicole facilitated Anticyclone under its Northward Planetary wave alteration

   Following up on previous article about PTS Nicole pushing the Jet Stream Northwards,   SFU animation  jet continued flowing Northwards all the way to the  North Pole,  quite extraordinary event.  It seems a Hurricane system more complex than just a mere strong Cyclone.   Because to the South of the displaced Jet Stream Wave there was a High Pressure system:

The Jet stream wave had Higher pressure to its South,  while there was remarkable dominating
Lower pressure over the Arctic Ocean,  the Cyclone dominated Arctic had a significant circulation makeover,  NOAA Daily composites October 21-24 2016.

Ex Hurricane Nicole appears to have displaced the jet stream Northwards

~Is not the first time an Ex-hurricane affected the jet stream...

   Now that formerly Hurricane-Tropical Storm Nicole approached Greenland,  something caught my eye:

SFSU jet stream animation October 14-18, 2016,   usually marking  Low pressures to the North of the main jet stream.   However hurricane Nicole exhibited some unique features which are interesting.  

Zoomed  SFSU animation Oct 14-18,  As Post Tropical Storm Nicole approached South East Greenland (end of animation loop),  the Jet stream bent Northwards,  as if the ex-Hurricane was a High pressure rather than a Cyclone.  Note the beginning of this animation small 993 mb Cyclone over Ireland having the Jet stream to its Southern perimeter.
