new REFRACTION method reveals Arctic Atmosphere morphing to allow more Cyclonic penetration

~Interface Adiabatic Index dwarfs its opposite Interface Inversion Index by 80%
~Method exceeds any other technique in identifying what is happening at the most crucial interaction  between Earth surface and atmosphere.


   The larger question given by a warming planet is what happens to Earth aside from its climate heating up slowly.  The answer is at the interface.   In darkness,  the surface to air interface is cold, very cold,  the land or sea ice becomes a reflection of radiative cooling. Eventually  exceeding,  overwhelming what heat is left in the lower atmosphere.  However,  air is a good insulator,  in this case the usual  layers a top the interface remain warmer,  this causes inversions.   The rate of cooling or lack thereof can be judged by how strong the inversion is.  Extremely thick sea ice over the Arctic Ocean mirrors land during the long night especially after land exhausted or radiated most of its energy to space.  Ice some 10 meters thick has very little heat lost to space.    Thinner ice has
much more radiation escaping,  this flux of energy alters the climate terrain.   The lost of thick sea ice has already affected the climate worldwide.   In the Arctic past, winter was built by darkness with a sea largely non existent, in effect insulated by sea ice,  the lower atmosphere lost its heat upwards to space in Autumn, Winter is created when land and sea ice accelerate this cooling process,   by heat radiation going at times 2 ways,  upwards and downwards.  


    Most remote sensing instruments fail to read physical bodies next to each other.
As an example the air right above open water ocean is often not the same,  the remote sensing achievement in determining temperatures at 5, 10, 100 or 200 meters above or below the sea surface is outstanding.     But as I wrote before ,  this precision may be questioned,   how we measure the temperature of everything at once is a matter of future progress.  What the horizon refraction method does is quite unique,  singularly a measure of the physical or thermal process at the interface at once.  Its precision is unquestionable.  A true measure of the temperature of the entire atmosphere is the dimension of the vertical sun disk,  but the thermal nature of the surface interface seen at once is invaluable.

The sunline on the lunar horizon

~Lunar horizon glow looks eerily similar to the sunline on Arctic Earth


                      Surveyor 6 , November 6 1967 lunar sunset on the Western horizon.
There is something very familiar about this,  of course its the sunline.   But wait there is
apparently no atmosphere on the moon.   The theory suggesting electrically charged dust causing a sunline is questioned here.  Of all EH2r records from a significant database of Earthly sunsets (from polar and temperate zones),  none have given a sunline due to dust,  it does not happen.   Sunlines are a pure atmospheric optical refraction effect.  



      To the untrained eye, it is hard to say which of these two pictures is from the moon or Earth,  the moon shot (left) should have a pitch black sky, and the Earth's brighter atmosphere gives away the polar sunset (right).  There is no doubt about moon dust on the lunar picture (left) given by the small aureola, similar to haze or dusty horizons on Earth.   But the sunline is unmistakably identical.  The rocky lunar surface is very similar to the sandstone Arctic gravel hill 3.5 km away from camera:


Arctic hill sunset October 14, 2014.  Remarkable
refraction effect caused a few km away,  not through a long distance of atmosphere.  But caused by air less than half a meter above the gravel hill.  It took very little gaseous molecules to cause this effect.

There was a very faint or negligible corona  because there was no dust or ice crystals (it was too warm for crystals to form).  There was light winds as well,  frozen ground reduced dust levels greatly almost completely.

   The absence of dust here contradicted the presumption that sunlines
are caused by dust.  They exist because of gas.  Until a dust sunline can be replicated,  a dust sunline is simply an un-observed theory on Earth.

    There is an unmistakable structure with any sun line,  if you zoom you will see red line layered below the brighter yellow which can be at times blue or green.  The red has to be below because there is less bending of red light,  it is a refraction effect.  Consider the same photo with no significant atmosphere and the line would appear greatly brighter than background.

  A careful look reveals almost identical sun line between Earth and moon,  the difference is of course in part due to different optical equipment utilized.  The moon's aureole was illuminated by moon dust,  but the sunline is a totally distinct feature.  Has nothing to do with dust as seen on the edges of the moon's sunline especially at left,  where the aureole dust above hardly makes a glow.   There is also a photonic disturbance below the main brighter moon sunline suggesting a red imprint of course not recorded as such.
 
     The actual physics of dust bending light uniformly would be quite exotic,  unless unique to the moon,  dust scatters light when photons are present.  The theory suggesting
that light gets bent,  creating a later sunset, indeed introducing focused photons making a layer of the micro horizon bright  has nothing to do with particulates.

       It is not inconceivable that the moon may have some daily outgassing similar to comets during their celestial orbits approaching the sun.   On the lunar surface there is a daily very steep rapid change in temperature,  a heat cycle familiar in the Arctic,  where micro surface thermal variations are responsible for great photon redirecting.  There is also an atmosphere on the moon,  said to be very weak,  13 degrees of magnitude weaker than on earth,  perhaps not always the same or uniformly everywhere on its surface. WD October 15-16, 2014

Extremely late in season spontaneous sea ice melting

~ Even when expected,  the look of vast sub-zero air sea ice melting astonishes


   In merely 3 days,  with air temperatures not so favorable,  a few degrees below zero degrees centigrade, but above average for this time of the year,  the greatest melting action so late  demonstrates the real nature of 2014 melting season,  which was really influenced by 2013 great cloud summer event.  To recognize a a wider recovery of sea ice,  one must see it more expansive than the year prior, and more thicker.  Piomas may recognize a thicker ice,  but the extensiveness is largely different than 2013,  when the ice melted in place without compaction.  The net difference is insolation of the open water around the lower latitudes of the Arctic ocean,  a recovery would not allow the sun the warm up sea water particularly at these latitudes.   This invites the stalling of accretion,  an eventual less thicker ice at next maxima. But also this scene shows that ice may vanish with air temperatures below 0 C.  This is a key factor in the coming wide open Arctic Ocean,  sea temperature in turn to be excessive,  warms up the ice to a critical temperature point.  When reached the ice simply vanishes,  the sooner it goes in spring time,  the greater the melt in autumn.  WD September 14, 2014

Spontaneous meltdown, a matter of ice temperature.

             North of Alaska new rapid melting area 120,000 Km^2 appears sudden,  but is more something to do with water and sea ice temperature.   Note buoy 2014C likely floating about in the wider open zone to the West , is reporting -1 C water,  likely enough to help further the thawing process.    What appeared more solid a mere 6 days earlier almost disappears overnight.  Despite -2 C weather,  which is permeated by a Low pressure system.  Sea ice appears most fragile when  the ice temperature is equal to surface water,  particularly at this time of the year.  The total accumulated heat by open water won't go rapidly,  only very cold surface air temperatures will stop this process.  WD August28,2014

40% ice? Resolution at Cryosphere Today radically misses wide open water .

           Cryosphere today ,  August 18, 2014 .  Infamous McClintock passage of the NW passage.  The same channel responsible for the death of 126 sailors of HMS Erebus and Terror fame in 1848, during the said "mini ice age".  Notorious for its perineal rough and thick sea ice until about a decade or so ago, it now opens completely every melt season.  So as some say, 2014 melt is similar to a "recovery" or archipelago sea ice looks massively menacing and a return to a clogged NW passage of old.  Well CTpresentation, as above,  may hint that there may be some form of return to the past.  Not so:

NASA Eosdis view of the same area August 17 2014.  The Channel Prince of Wale shore has more than 20 nautical miles of open water, with very little ice,  not at all as presented by CT.  This probably means that CT uses grids in excess of 20 nautical miles.  Of which if there is 15% of ice the data would evaluate a wrong Area number.    So now the Passage is about to open by winds and further melting. But using CT data one would leave his boat moored in Baffin Bay or Cambridge Bay rather than attempt the passage at all,  and eventually return to the South if using the same coloured map.  WD August 20,2014

7 day ice melt, as fast as it goes, but late in the season

Despite clouds NOAA Visible wavelength sat pictures clearly depict rapid melt and clockwise rotation of North Beaufort Sea Ice.   The wider open clear water near Banks Island is August 16 (compared to August 9 1 week earlier),  there is no ice to draw from this Island, therefore the ocean appears really clear,  the rest of the August 16 picture is veiled by clouds.  The big 160,000 Km^2 North of Barrow circular melt  has lost most of its broken internal ice,  may be not enough to register on the CT Area data, clouds don't help showing that it expanded as well.

Rapid disintegration rate may not be measured accurately because there is more than 15% of sea ice left.

   There is lateral displacement of sea ice every where as seen here for NOAA visible pictures between August 9, 2014 (mostly clear) and August 11, 2014  (large clouds with shadow top right).  What is seen is a new large area of open water about 160,000 Km^2 (on the 9th) just North of Barrow Alaska,   expanding rapidly wherever there is ice,  but it easily has some remnants in extent more than 15% which will not let this expanse be measured in area until there is > than 76% of open water.  This leaves measurement metrics a bit off, and particularly strange, when we can see great melting but no daily records of it can be noted.  Eventually when there will be less than 14% of ice left in open water zones the drop in extent and area will show rather large on daily data records as seen on JAXA or  Cryosphere Today.  But the area to the South of Expanse has roughly 50% water, all of this is considered as 100% ice.

    Rapid ice shoreline melting

August 6 NOAA image (with clouds lower left) compared to August 11 PM NOAA demonstrates rapid melting in progress at every ice edge.  But envelopment must occur first.  The main process of compaction is 2 pronged,  first the main pack is pushed together,  then the ice shore scatters with thicker ice moving inwards faster,  leaving thinner ice behind (by winds).  The thinner ice gets enveloped by warmer sea water when exposed to sunlight.  The ice, known by buoy data, is at the same temperature
as the sea surface,  any warming obliterates it to water.   A second melting process,  quite interesting by its look,  may be a precursor to a complete melting of larger chunks of sea ice.  A melting occurs in the middle of a pack,  likely because there was thinner ice laced with leads there.   Thawing spreads outwards by sunlight warming sea water ever more so taking hold of the region.    Compaction moves the ice as a whole,  warmer water reaches the scattered ice and envelopment is amplified.    Again the rate of melting is extremely fast,  considering the ice appeared to have withstood the onslaught of summer hardly unscathed,  but it is not so, sea ice was transformed, from hard and cold to as warm as sea water and soft,  ripe for elimination.   In 2007 this process occurred earlier with a combination of warmer weather and total insolation which devastated the thickest pack ice very quickly.  But same process,  even with lower cooler sun, it happens just as much.  WdAugust11,2014
Clouds forgiving us a sight, NOAA August 6 to 12 visible picture again brings out a clear break down
of shore ice vanishing as quick as I have ever seen it,  thanks to buoy data, we know why,  again data remote sensing numbers don't suggest,  not even a mere hint of this action.  So the proper interpretation
of ice status is not 2 dimensional but 4, consisting of area,  thickness and  temperature.   A glance of larger ice extent does not tell the whole picture. For instance,  the ability of sea ice to change the weather depends on its temperature,  not acting as a heat sink affects Global Circulations which in turn affect the pack same as any meteorological feedback mechanism.  wd August 12, 2014

15,091 km^2 lost but likely no noticeable record of it

~Must be aware that overall records need a closer look


August 5-6-7 2014 NASA EOSDIS  Lower left cloud is 5,  clear air is 6 and Upper left cloud is 7.  Of the East Siberian Sea area.  The main pack is retreating steadily due to high pressure circulation,  but it leaves readily melting residual sea ice in its wake likely affecting the overall result when using area or extent 15% threshold as done by JAXA or Cryosphere Today. Instead of approximately 15K km^2 retreat,  the numbers from the 15% threshold method apparently would show much smaller result.  The current favourable for compaction  action in the East Siberian sea sector also is part of a larger stronger Arctic Basin Gyre movement which makes the other side of the Pole pack expand Eastwards in the warm North Atlantic,  giving the impression that there is no movement or action in that quadrant.   The over all result makes Sea ice extent and Area numbers look quite small. While there is indeed serious movement and melting going about.  WD August 7, 2014

What is the difference?

  Cryosphere Today very much like 2007 and 2012 so far.  Both preceding years have common sea ice features.  But 2014 has likely over all thinner ice than 2007 and 2012.  WD July 2, 2014

And NOW the Ocean is the HEAT SINK

~Top of sea ice Final stages of a buoy before it floats on sea water.


    June 13 2014,  buoy 2014b sits on top of sea ice with heat taking hold of its surface fuelled by the sun:
   The ice was mostly colder than air and sea water.  Ta>Tw>Ti,  sea ice holding the buoy up is a heat sink,  very bad for its health.   Ice survives between thermistor 5 and 17 ,  about 120 cm thick.

   2 weeks later,  the sea becomes the heat sink:
    Ta>Ti>Tw,  sea ice barely survives between T(9) and T(16),  70 cm thick really soft and rotten.
Was it not for natures glorious ,  no brilliant! - latent heat of fusion point which changes as sea ice becomes saltier,  the ice exists at higher temperatures than sea water!  Now we've seen what happened,  in a mere 2 weeks, sea ice owes its existence to sea water temperature,  which is nearly constant.  While soon there will be no more surface air heat to absorb ,  because top of sea ice is melting fast (40 cm in a week),  while bottom tries to last.     WD June 30, 2014
   Day later evening, inexorable progression towards annihilation, what remains of sea ice becomes warmer and warmer,net solar forcing exceeds the cooling effect of the ocean which itself warms since having become a heat sink.  But the ice survives, nevertheless the onslaught,  this can be seen by rapid diurnal cooling, (extreme left of graph), while sea water exhibits hardly a wave whimper (extreme right).   But time is running out since 0 C progression with thermistors, from left to right, continues.  Wd(july 1,2014)
