Monster hot sst from Pacific finishing off broken up sea ice extremely rapidly

~The damage was done my movement of sea ice,  the job of melting is finished off by warmer sst's.

    July 19-July 31 JAXA loop demonstrating the process of total disintegration of sea ice in the Pacific sector of the Pole,  with extreme rapidity.  We note lesser but significant melting everywhere else with open water. 

  Zoomed July 29-31:
  The East Siberian sea ice Peninsula (1.5 million km2 strong)  is in the process of completely disappearing,  when so looses cohesion, as a result,  sea ice scatters and nulls the extent numbers loss a bit,  only to be corrected when every pan of pack vanishes.  WD August 1, 2018

Atlantic front race to 85 North vs Pacific waters massacre

~Central Arctic Basin 2018 is #1 is lowest extent

~ Beaufort sea and CAA make up  400 K difference with 2012, while 2018 has 464, 000 km2 more sea ice than 12
~ Along with other peripheral seas, which will have near 0 extent come mid September,  2018 is technically #1 at the moment.  

   CMC reporting whopping +9 C sea surface temperatures in the Bering sea can only mean one thing:

  We note super fast melting conditions North of Bering sea,  with ripe conditions enhanced by a High pressure Gyre favouring compaction and flow of  extreme warm waters finishing off straggling sea ice pans.  On the Atlantic Front,  we see Fram Strait loosing sea ice rapidly due to no flow conditions, but also a race towards a 85N on the entire Atlantic sea ice shore line.  The NE passage is about to open first, equally as expected in April,  the NW passage is clogged with sea ice but should open partially much later. 

     What about the black spots appearing in waves on the JAXA animation above?  They are open water zones opening closing rapidly as captured 82 N 176 W:

   The JAXA dark spots indicate rapid movement of sea ice sometimes leaving open water gaps which may fill with rubble and slush,  is part of the same process detected North of Alaska about a month ago.  Rapid motion of sea ice may be interpreted as steady sea ice albedo until the slush turns to goodbye waves,  when the entire pack collapses rapidly as occurring North of Alaska at present.  WD July 30 2018

Vast 2018 region of Arctic Ocean sea ice in much worse shape than 2012

~Gyre area sea ice about to totally melt or simply move away very rapidly
~15% extent rule certainly favours 2012 as having similar sea ice extent than 2018 in same region.

July 26 2018 Gyre region sea ice is in a catastrophic state.  We can see the blue ocean overtaking the pristine white sea ice. 

2012 same date same place was in bad shape as well,  but not as terrible as 2018 deep in the Gyre zone.

A closer look:

  In all technicality 2018 has less sea ice than 2012 for a vast area,  but the 15% extent rule makes 2012 similar.   Hindsight being 20/20 ,  we did not know how bad 2012 was until a very strong
early August cyclone came through,  having the benefit of this history, we now know that 2018 is
very much going to overtake 2012 very soon,  at least in this region,  there should be not a lot of sea ice left come late September. WD July 27,2018

Current sea ice extent is getting close to be nearly equal to all time melt year

~After July 23 more than 200K drop,  on July 25 2018  there is a +421,497 Km2 difference in extent between 2018 and 2012.  
~There are ample reasons to believe that 2012 extent will be caught up soon

   2018 Canadian Arctic Archipelago has indeed the lasting ice imprint of very cold Upper Atmosphere as measured by vertical sun disk measurements,  there is no contradiction,  one area
of the Arctic may be quite cold while the majority of its lands and seas much warmer.   Each year varies,  2012 Northwest passage opened very early,  does not look so for 2018.

CAA current July 25 sea ice extent. 2018 trace is in black, 2012 light brown.  There is at least 200,000 km2 of ice to be gone come September/October minima.The current lag with 2012 is about 200K.  

   Record extent drops are primed North of Alaska,  July 22 to 25 JAXA loop suggests at least 200,000 km2 ready to vanish quite soon. 

   Chukchi sea rapid melting is partially masked by counterclockwise flow of sea ice doomed by very warm sea water next to Wrangle Island,  we note to the right,  East Siberian sea rapidly opening up,    not being replenished by Laptev Sea already widely ice free, East Siberian should have very swift drop in extent within next few days.

Bering sea black melt potential

~2018 slow start melt season picks up not only speed but darkness

   From AMSR2 JAXA daily extent melt numbers July 21-22-23-24 in km2/day:

  2018 has a staggering dominating melt pace; 

At the moment, the most significant difference between 2012 and 18 melt can be seen just North of
Alaska, whereas the ice flows clockwise and counterclockwise respectively, the difference being
extensive over a long period of time warmed Bering sea waters in 18 compared to 2012 Beaufort newly exposed sea surface:

We look for "Goodbye Waves" which are pre total melting of ice over a sea surface,
2012 Beaufort sea had then very few, mainly because of sea ice drift movement
dominating an apparent melting, while same date 2018:
Multiple Goodbye Waves signify rapid melting is occurring very likely from much warmed sea surface WD July 24 2018

Beaufort area monster melting at present

~Sudden melting from long in duration rapid movement  of crushed sea ice with multiple leads warmed by sun rays

Last 3 days ending July 22 2018 JAXA extent depiction nothing short of  amazing,  despite partial cloudy conditions extremely fast melting is occurring easily more than 100,000 km2 in a day in this area alone.  As we can see,  with sea ice moving opposite to normal Gyre current. 

Coming with the counter clockwise gyre current is this CMC depicted +9 C sea water,  certain demise for any piece of ice. 

   And ECMWF July 27 forecast runs this water strait towards the main surviving pack.  WD July 23,2018

2012 vs 2018 on three fronts, circulation dominates, 2018 is slushier

The most interesting area is Beaufort to Bering sea:

 July 4 to 20 2012,  there was more open water over Beaufort because the Gyre circulation was largely unaffected by cyclones till August.  Note the ice pans maintaining about 100 km in diameter,  moving clockwise.
Absent Beaufort area 2018 sea ice morphology is largely similar to 2012 same period of days.  Except the circulation is counterclockwise and the majority of  surviving sea ice pans are smaller at about 50 km in diameter,  observe the slushier aspect of the ice as well,  pulverized by greater motion amongst significant open water.

 The Atlantic front difference is fascinating as well,

Atlantic Front July 17 2012,  note the ice shoreline hugging Franz Josef and Svalbard Islands,  
There is at present about a 250 km retreat towards the Pole for the entire Atlantic Front.   
 Chukchi and East Siberian seas has equally a vast difference:
2012 2017 and 2018 July 20 animation ,  2012 is the one with most sea ice,  we note 2018 incredibly warm Bering sea at some points +10 C hot.  And also the counterclockwise flow of sea ice ice right into this warmed sea.  It is a new Fram Strait by virtue of a warmer winter with no sea ice.  WD July 21 2018

2018 vs 2012 what is the difference ? about 200,000 km2 in extent

~Because Hudson and Baffin Bay + Kara sea still have not melted completely

     Kara had a late freeze up South of Novaya Zemlya  in 2018,  but still has some sea ice,  while 2012 close to 0 one day later (selected due to clouds).

Hudson + Baffin Bay with still lots of sea ice compared to 2012,  meaning the large difference is in Beaufort sea,  which as we know,  is flooded still with a continuous stream of sea ice.  WD July 19 2018

Massive Counterclockwise river of Arctic Ocean sea ice floods Beaufort sea

~All while there are at least 2 clockwise gyres or sea ice vortices near by.
We can note that the near entirety of Arctic Ocean pack is turning counterclockwise,  except about Beaufort Sea receiving a gradually thinning pack coming from Russia, before that from the North Atlantic.  There are 2 smaller clockwise Gyres North of Alaska, but the main influx of ridging is towards its shores giving the illusion that this years melt is slow.  In fact as this JAXA June 28 to July 14 animation demonstrates,  the  Central Russian open water pack has vanished because of melting and the Ostrov Komsomolets Islands and Ozera Taymyr Peninsula acting like an ice dam,  and so goes for East Siberian Islands.  Once foreseen switching back to dominant High pressure North of Alaska will return,  the compaction will be ruthless in the other turning direction.  A couple of things to note:  The Normal Arctic Ocean Gyre has been overtaken,  Banks Island no longer creates open water by its circulation,   is extraordinary that Beaufort Sea has open water at all, the source of broken up sea ice appears endless at the moment.  In addition to Beaufort sea,  new Fram Strait's are now in Chukchi and Bering seas,  the North Atlantic sea water not receiving any sea ice can only warm further for extreme melting and be on the ready for when the Gyre driven Transpolar drift resumes.WD July 15 2018 

Viewed from space dark sea ice is toast, but may last a long time

We know the sea ice formed late in Barrow Strait,  this ice was thin at maxima in May (not like overall extent of  all sea ice),  made thinner by extra snow layer. Eventually it disappeared on July 7 2018, but for a persistent thin zone South of the Island, mainly in blackish.  The older in age first year ice has greyer shades.   These surviving sheets should eventually melt and disintegrate.  So did the blacker sheet at about July 12.

    If we compare these mechanics to the larger over all sea ice areas,  we now must look for the tell tell black shade depicting thinner sea ice. WD July 16 2018

Beaufort rapid retreat met by thinning sea ice replenishment

~Super fast 140 nautical miles in 8 days
~10 .8 nautical miles a day

Top of GIF June 25 to July 8 rapid sea ice retreat is met by equally fast pack ice replenishment    But the quick velocity pack is thinning and is running out of replacement capacity.  It has been this kind of melt in this area.

The retreat in Beaufort is met by a contrarian recently created wind current in Bering sea adjoining Alaska. This creates an ever so smaller compaction block as Bering sea is warm.WD July13 2018

Hollowing from within at 80 degrees North, the untold story

~Longitude 147 degrees West
~ Severe movement is destroying the fabric of stable sea ice

    2012 greatest melt in history  , about 80 North 147 West,  more or less stable sea ice which mostly all melted at maxima.

  2012 same date and location there is movement ,  as one big unified sheet.

    Same date same frame capture but 2018,  really broken up sea ice.  This a feauture of 2018 current melt.

     With much more open water barely recognizable sea ice structures  moving individually much faster,  not at all like 2012.  A completely unstable configuration prone to absorbing more sun rays  since there is much more open water.  On record,  the 15% extent  rule makes this nearly 100% sea ice.WD July 9 2018

Sea ice extent analysis should be holistic

~Given the tools we have ,   ie the lack of proper ressources and using archaic meant for another era measuring methods,  we must study sea ice more profoundly.

2012 did not have coldest CTNP over the CAA in 20 years,  therefore a massive ice imprint,  much more significant than 2012,  as we can see,  with 2018 easily 400,000 km2 wide:

2012 sea ice same day looked emaciated and vanished. 

Before we judge 2018 extent magnificent recovery,  we must think of winter past,  when the lower CAA was really seasonally cold or colder.  Despite the entire Arctic Ocean being exposed with warmest weather. WDJuly 8 2018

Possible rudimentary ice thickness measurement mistakes requiring a revision

~We look here at specific sea ice anomaly charts versus actual observations which contradict each other

    First brought up June 10,


    PIOMAS May 2018 ice thickness anomaly map was exposed to have major flaws around Novaya Zemlya Island Russia.   Now we look at the whole region,    Note  all the JAXA July 5 NE passage water  (right) was once in said to be reddest thickest sea ice anomalies portrayed below:                                                                                                                                                                                                                 

                 I would suggest thicker snow layer on top of red sea ice zones as one of possible or the major explanation causing erroneous ice thickness  estimates. WD July 6 2018

Supercomputers are no good at flipping coins. Can't grasp what a CTNP is.

~Supercomputers are perfect,  but without a threshold of consciousness , they need ears and observation skills.

~Missed massive positive temperature anomaly for half of North America.
~Computer shows that it has no cognizance capable of recognizing a Vortex circulation.

Here is one of accuweather's  latest sketch:

   A dangerous ,  certainly multiple record shattering heat wave for North America.  We note especially the green cooler zone North of  the Great Lakes, is where the Canadian Arctic Archipelago CTNP lies (Cold Temperature North Pole,  fancy highly technical description simplification for the Polar Vortex),   which dominated the North American and Northern Hemisphere weather circulation most times since November 2017.  So how come the same super computers long term forecast gave this:

  Amazingly weird Accuweather long term forecast,  seems the model did not realize that the "below" blue zone temperatures was accurate,  and can only be part of a vortex structure strangely mangled winter like,  since Baffin Island can't be warmer like this in summer, when influx is from very cold North Atlantic.  Note the "Above" zones,  at least almost got State of Maine right.  Essentially a Vortex circulation is counterclockwise,  would drag much warmer air towards the Northeast to the South of it.

    NOAA July 2 temperature anomaly,  look at Baffin Island and Western North America.  This is exact picture of what as CTNP would do in summer.  Colder to its Southwest warmer to its Southeast.

   Therefore I would kindly request supercomputer to read my yearly April projection,  should not be that hard,  I read the models crunching's daily,  reading my humble forecast once a year should not be much of an effort...

Note NOAA + ECMWF models also got it wrong,  not only Accuweather but Weather Underground as well, it was foreseen as such:


Please note sensational new methods which enabled me to crack the temperature resolution syndrome:


Also my rudimentary sketches which turned out to be accurate:


    Note to human experts,  is nice to beat the computers at something,  I only win at computer chess 3% at the time.WD July 3,2018

Massive more static ice pans or fast moving broken up sea ice, which ice-scape melts fastest? Answer found in 2007

We first look at 2012 July 2 pack Just North of Beaufort sea:

2012 melted more in place, with extremely large pack ice pans, sign of slower movement.
   Same location July 2 2018, this static image is misleading, the sea ice is moving very fast, compressing in some parts scattering in others. Sun rays are effectively penetrating in the core pack more than 2012. There is a lot of 2018 open water not measured by the 15% rule as well.
   Beaufort sea 2007 end of June till mid July,  pack ice 2007 was more like 2018 than 2012.  But with apparent slower movement.  We know the great sea ice vanishing result in 2007,  which had more extent of much thicker sea ice than 2018 on July 2.  This indicates a strong melt is in the cards for 2018....WD July 3 2018

Velocity driven sea ice, apparent slow incremental melting is about to change suddenly

  Beaufort sea,  there was more open water a while back,  sea ice is constantly replenished until it becomes too scattered which evidently is demonstrated here with JAXA extent June 28,30 and July 1 (the darkest sketch).  Eventually the ice will melt further as it disperses,  it is surely a most effective way of melting sea ice but takes more time to show.     Western entrance of the Northwest passage will show very few clues about this if observed from Banks Island Canada.  Basically one static sheet of sea ice reflects more light than broken up ice pack.  Of course a more static sheet would allow an un-intruded area of sea water to warm further,  but the melting goes slow at the main pack shore area. Here we have sea water warming up deep within the pack core.  As this animation demonstrates,  eventually a greater deal of the loose pack will be infiltrated by warmed surface water unmixed by winds.  WD July 2 2018
