The cold high-pressure over Scandinavia will repress the mid-Atlantic gale (in the lower left of the above map), eastward to Spain. West winds beneath it may swing mild air up over Spain, changing snows to rain there in two days. (Below: GFS 48 hour forecast).

The low-pressure is then expected to loop north from Spain to the Atlantic west of Ireland, pulling milder air north and changing the snows to rain over France and Italy by four days from now. But Great Britain will continue to get snow. (Below: GFS 96 hour forecast.)

ARCTIC SEA-ICE –Super Surge Alert! (Look Out Below!) (This means you, Europe)

An extraordinary plume of above-normal (but still sub-freezing) air is pouring up to the Pole from the Atlantic. The spike in the mean-temperatures-above-eighty-degrees-latitude graph, if not “unprecedented”, is highly unusual.

DMI5 0223 meanT_2018

This is caused by high pressure towards Eurasia and low pressure towards Canada and Greenland creating a roaring south-to-north flow from the North Atlantic over the Pole.


However, as I have pointed out to the point of sounding like a broken record, (IE “repetitive”, (for those of you too young to have experienced a record skipping on a record-player, and who think a “broken record” involves record temperatures), ) we do not get these milder-than-normal temperatures at the Pole without the displaced cold air freezing the socks off people in more southern latitudes.

The big high-pressure over the Eurasian side of Arctic Sea has a southern side, which creates the east winds of Mordor, bringing Siberian bitterness west into Europe. Here is a map from an Italian Site, worried about what is looming.

Super Surge 1 Gelo-21Feb18

I’ve been watching the UK Met maps, and must comment that they do a bad job of showing the east winds from Mordor. They never show a cold front progressing from Siberia to England. The isobars hint at the deepening chill, and at daffodils ducking back down into the dirt, but the fronts they draw on their maps give no clue. Here is their map for this coming Sunday.

Super Surge 2 65134687

The BBC is reporting the Met Office is issuing “amber alerts”. (Hat tip to ).

Parts of Germany may see a fortnight pass before temperatures get back above freezing. Expect headlines.

North America will also likely see the displaced arctic air swooping south, though it may take longer to develop. It is already cold in the west, but, if the pattern develops as the veteran forecasters D’Aleo and Bastardi are forecasting at the Weatherbell site, the east of the USA may make headlines in early March, as a classic negative NOA builds high pressure over Canada and Greenland and low pressure off the east coast.

Super Surge 3 gfs_z500a_5d_noram_65(3)

The thing which I think may be a fly in the ointment is that nothing is truly “classic” in the current situation. Why not? Because the sun has gone “quiet”. All our hard-gleaned wisdom, that goes into what we define as “classic”, is based around much that is dependent on the sun being “noisy”. But the sun’s face has gone blank. (After a couple spots rotated across its face, and gave the earth a small blast in passing, the sun’s face is again spotless.)

Sunspots 20180223 latest

In fact the current sunspot cycle (#24) resembles the sunspot cycle at the start of the Dalton Minimum in 1798 (#5).

Sunspots Layman's January sc5_sc24_1

Much that we describe as a “classic” weather pattern is therefore subject to a degree of doubt. Patterns may not behave as they behaved in the recent past, but rather as they behaved in 1798.  And we have poor records from that long ago.

This does not render old-school forecasters obsolete.  Some rules do not change. The freezing point of water remains the same, and so on and so forth. However I think we should expect the unexpected. Forecasters should stay on their toes, and as soon as they become aware a pattern is not behaving in a “classic” manner, they should use all their wisdom to gather an idea (called “a forecast”) of what the pattern actually is up to.

The thing to watch for in the current situation is the building of the “classic” blocking-high-pressure of a negative NAO over Canada and Greenland. If it fails to form, expect the unexpected.

There is another thing fun to watch for, in the current situation. There are certain Alarmists who will note the milder-than-normal temperatures over the Pole, and will make a great big media event over announcing the planet is facing Global Warming, and they will stage this event in some locale roughly a half hour before the winds from Mordor arrive from the east, and a howling blizzard ensues.  People leaving the press conference will get stuck in the snow.

If this classic scenario fails to form, I will be deeply disappointed, for I confess I find such spectacles deliciously entertaining.

ARCTIC SEA ICE –Comparison with 2006–

I was listening to some Bach yesterday to mellow out my temper, but unfortunately was on a PBS station which injected a bit of Climate Change hoopla into my brain before I could change the channel, the result being I was anything but mellow. The editorial was so full of incredibly distorted news that I’m surprised the speaker’s nose didn’t grow so long it poked out through the front of the radio.

Just for an example, every El Nino makes the waters warmer around Australia, which allows waters to get hot enough, in the shallowest reef-waters, to “bleach” some coral. The coral dies, and then comes back after the water cools. I’m not sure what percentage gets bleached, but it isn’t all that high. I’m not sure how long it takes for the reef to recover, but it isn’t that long. Like a forest fire in the Pacific Northwest of the USA, “bleaching” is not pretty, leaves a short-term wasteland, but is a part of the natural cycle of things.

I know all this because there was a “coral reef bleaching scare” around ten years ago, and I paid attention to a degree where I actually visited Australian websites. Some fellows at resorts were irritated that they might lose customers because people would assume the reefs were dead, while other fellows thought tourists would come if the guides played on a theme of “see the reef before it is too late.” However I soon understood the reefs were not anywhere close to dying out; bleaching had occurred before, and the reef always recovered. Some websites frequented by scuba divers were downright contemptuous of the media, and how ill-informed the reporters were, and how some scientists were pandering for funding, to study reefs the scuba divers already knew about. The divers joked the scientists were looking for a paid vacation. In the end the scare blew over and the coral recovered.

The PBS editorial I accidentally listened to was replaying all the exaggerations of the old scare, based around this latest El Nino. For example, in an area of sun-baked shallow water up to 99% of the coral can die. That is a true fact. However it is a gross distortion to use the “up to 99%” figure for the entire barrier reef. Yet the editorial said something along the lines of, “A professor and his students were reduced to weeping because up to 99% of the Great Barrier Reef had died.” That may not be an out and out lie, if you parse the sentence with a lawyer, but it gives a false impression, and therefore PBS seemingly is misusing its funding. It is suppose to educate the public, not bleat propaganda. (The (unnamed) professor is suppose to do the same.) (Weeping isn’t scientific, and weeping is known to, in fact, cloud scientific objectivity. A bunch of bawling students is therefore not a sign of a good teacher.)

The editorial went on to do the same with other facts regarding sea-ice. My favorite involved blithely explaining away the cold hitting Europe as “cold displaced by the heat at the Pole.”

Joe Bastardi at Weatherbell site  posted a Dr. Ryan Maue forecast map of snow in Germany this week.

Germany April snow 2 gfs_tot_snow_eur_29(1)

I was curious as to whether the forecast had verified, so I checked back to the Weatherbell site, and Joseph D’Aleo was (as usual) right on the ball. I learned temperatures over Germany were ten degrees below normal.

Germany April snow 3 ncep_cfsv2_4_t2anom_europe(2)

And Pierre Gosselin reported to Joseph,

“Winter transforms Germany’s Thuringia Forest into a winter wonderland today. Massberg webcam photo 11.07 a.m.

Newsite Thuringia Antenne here writes that winter has returned and will stick around for awhile, reporting of icy roads, accidents and cold. Meteorologist Dominik Jung of forecasts 5 to 10 cm of snow across wide regions of Germany, especially Bavaria and Thuringia.

The Rheinbrecke at Rees had to be closed for over an hour and a half early this morning due to accidents from icy conditions, the RP Online reports here.”

Germany April snow. Winter_massberg_April_26_2016

While it is true Europe is smaller than the Arctic Ocean, (3.931 million square miles versus 5.427 million square miles), when you include the area of Atlantic Ocean covered by the cold hitting Europe you wind up with an area larger than the Arctic Ocean. Nor is the entire Arctic Ocean above normal. Slightly less than half of it is, in fact, below normal.

Germany April snow 4 gfs_t2m_anomf_arctic_1

None of this was mentioned in the editorial, of course.  In the end it basically dissolved into a diatribe against people who vote out Alarmists, such as Australians. What was most nauseating to me was its “science-is-settled” attitude, which accepted guff as gospel.

I have my doubts about recent record-keeping, due to some being polluted by  “adjustments”, but, using those records, we are indeed feeling the effects of a large El Nino, and the air temperatures of the world are at “record highs” as the sea-ice-extent is brushing “record-lows.” I don’t find this particularly alarming, as records are set all the time, when the period when the records have been kept is relatively short.  The last El Nino did indeed set a recent record, for the central Pacific, but didn’t for the waters just off Peru. Off Peru the 1998 and 1982 El Ninos were “the worst ever”.  In any case, I’ve been expecting a lot of hubbub to be made about this El Nino’s mildness, and the word “unprecedented” to be used a lot, and the PBS editorial didn’t disappoint me.

What is always interesting to do is to search the historical records we have from the period before modern records were kept.  They are full of surprises, and in fact it was my study of the conditions the Vikings in Greenland lived under that first alerted me to the fact that the word “unprecedented” didn’t include a huge swath of history.

I started poking around in the past, looking at low sea-ice extent, and I didn’t need to go far to find an example that surprised me. It was the year 2006, which most think of as a year with higher ice-extent, because most focus on September and not late April. I found a good site for making such comparisons, where you can erase all the years you don’t want charted, and avoid facing a hopeless tangle of graphed squiggles. I thought it would be interesting to compare 2006 with 2012, (2012 being the year with the lowest extent on record). Here’s the site, so you can do your own comparing:

What is interesting is that 2012 was above normal, while 2006 was at record-setting lows, at the start of May. By September 2006’s extent was barely below 6 million km2, while 2012 was well below 4 million km2. In other words, all the hubbub about how low levels now are might actually mean we are in for a year like 2006, rather than 2012.

At this point one runs into a lot of talk about how much more solid the ice was back in 2006, versus how flimsy it is now. So I did a bit of checking. People have been skiing from 89 degrees north to the Pole for over ten years, so I went and looked at the “final degree” diary for 2006. Temperatures were milder that year than this year, and April  17 had this intriguing headline.


Reading a little discovered this:

We have crossed difficult leads of open water today, where we also had to use our two large sleds as bridge to get across. This we can do on two-three meter wide leads. We lash the two sleds together to make a catamaran, and push them out in the water. This raft floats well and becomes a stable platform; we then crawl across to the other side one after another. This system works on small leads, but on wider leads we need to find a crossing point.

We did 15.5 kilometre on our ten hour long day. It’s now 46 kilometres left to the Pole, and it looks like we will make it with good margin. At the end of the day however, we came to an enormous lead, 3-400 metre wide. We made camp nearby this lead, and Thomas and I went out to look for a crossing point for tomorrow. Pressure ridges and large leads have one thing in common; they don’t last forever. When we meet such leads there is just one thing to do and that is to walk along it until we find a crossing point. They can be several kilometres long but sooner or later the lead will close. The good thing about such leads is that they take up a lot of the movement in the ice and we hope conditions are more stable on the other side.

OK, that is 2006, when the ice was “thicker”.

Now let’s evesdrop on 2016

From April 14

A long and hard day. Lots of snow on the ice, and a lot of rubble. Not extreme, but it’s there all the time…

Final Degree 1 in-the-ice

From April 16

Beautiful day, sunny but cold. Also today heavy walking, but nothing so bad that we have to turn back. The drift has changed direction and has almost stopped up.

Final Degree 2 ice-2

Now, if I was like PBS I would never mention that they later came across open leads. I’ve made my point: The ice was thick and piled up this year. However, because I am in love with truth, I’ll mention the leads.

From April 17

Just slightly some wind, and it was in our back. Temperature probably around minus 30-35.

And drift was almost zero. We got into better ice, less bulky and with hard snow. We followed a new lead that went straight north for almost an hour.

From April 18

We skied 18 Km, same as the day before. Lots of snow in the ice, but good conditions. A lot of large pans.

From April 19

Sunny, a bit wind from the back, warmer aprox 25 under.

We met an open lead right away in the morning. Struggled there for a bit, but came over. After that we had to jump several cracks, and did a couple more leads…

We then meet the mother of all leads just before camp time! Luckily it had one point that was possible to cross. We went over and came into camp at 20:15.

There. That is what real reporting looks like. You report truth, not just what supports your theory.

The “Race Against Time” expedition experienced the same arctic landscape. They started further south, experiencing some leads at the start, but then fought through a great deal of pressure ridging, which they described as “boulder fields”. Later they too came across the leads close to the Pole, and displayed their unabashed bias (apparent throughout the trip) by stating, “Strangely warm day around -10C. 8 hours trekking today. Reached a huge expanse of water, which is bizarre so close to the North Pole.”

They should have read up on 2006, for then they would have seen that the temperatures they experienced were colder than 2006 through much of their trip. Rather than “strangely warm” they should have stated 10ºC  was”temperatures like 2006″. Also if they had researched they would have known that the adventurers in 2006 also found leads near the Pole. Maybe they would have even researched to a point they would have known there were leads near the Pole in 1987.  It’s not so “bizarre” after all.

Barneo 6C 3-subs-north-pole-1987

I always admire the people who ski to the Pole. The oldest has been 69 and the youngest has been, I think, 10. However the “Race Against Time” crew got a bit too maudlin for me.  On one hand they had to promote how “delicate and fragile” the arctic was, but on the other hand they had to make it sound like they were up against hardships only supermen could endure, and this made them describe the pressure ridges they had to haul heavy sleds over as being like the Himalayas. Wrong.  Making pressure ridges sound huge is politically incorrect, if you want to promote the idea all the ice is melting.  They forgot the political cause, in their lust for self-aggrandizement.

Fool Ranulph

All I can say is, “Put on a hat, you fool!”

To return to more mundane matters, the last “whirl” faded away from the Pole, pumping a high behind it. This has cut off the export of cold down into the North Atlantic, but not before the trough mentioned at the start of the post was filled to the brim with cold. That trough will slowly drift across Europe to the east, and some milder temperatures will finally return to Europe from west to east as that trough moves to Russia.

It looks to me like Pacific air may try to generate the next “swirl” at the Pole, but the models suggest that low north of Iceland will be the next low at the Pole, splitting the high pressure in Frem Strait in half. Hmm. I guess we’ll see what we see.

O-buoy 13 has been experiencing dull weather, cloudy but with little snow, and steady temperatures at -10ºC.Obuoy 13 0429 webcam

O-buoy 14 has been producing the better pictures, and reminding me of what originally attracted me to these cameras. (Beauty). Temperatures have been going through a diurnal swing between -7ºC and -15ºC. It’s gradually clouding up.

Things remain fairly dull, usually, until the thaw starts, but perhaps the Alarmists will give me more to write about.


ARCTIC SEA ICE –Yet Another Swirl–

Well, it is happening again. Warm air has swirled up to the Pole, where of course it rises, and forms low pressure right where the textbooks say the air should be sinking, and there should be high pressure. At the risk of boring those who visit this site often, here is the textbook idea:

Polar Cell cells_mod

This winter there has often been rising air, rather than descending air, over the Pole, because the Creator doesn’t need textbooks. In fact He never bothered go to college, because according to stuff I’ve read He was something called “omnicient” even back before He invented time. I wouldn’t know about that, because I do need to study, and even then I don’t know all that much. But I do know when the textbooks are wrong.

I think they have been wrong this winter because the El Nino pumped a lot of extra heat into the atmosphere, and, because our planet is always trying to smooth out the difference between hot places and cold places, the jet stream had to become more “loopy” (meridienal) to transfer the heat to the Pole. Rather than low pressure parading around the Pole in a nice, orderly “zonal” manner, lows have headed right up to the Pole itself.

At times it is possible to use the above textbook diagram, even with a low sitting atop the Pole. You just assume the descending  air has been displaced, and look for a high pressure area away from the Pole, and call that the “new center” of the above diagram. But the problem is that sometimes there are two, three or four high pressure areas, and they actually seem to be parading around the low pressure at the Pole, as if the above diagram needs a fourth circulation and a fourth cell, (to the left of the polar cell) called the “super-polar cell”, for at times the theoretical “high pressure at the Pole” has a hole of low pressure in the middle, like a doughnut.

Other times I think that towards the Pole the Coriolis effect is different, and the atmosphere can’t be bothered parading around in circles. If it has a job to do, it takes the shortest route. If it has El Nino heat to be rid of, it just heads to the Pole and gets rid of it, and to hell with the textbooks.

The current map has a bit of the “doughnut” look, with a ridge of high pressure being pumped across the northmost North Atlantic behind the polar swirl, though the storm will not linger at the Pole long. The “swirl” shows up nicely in the temperature map.

Be that as it may, everything is about to change. Even before we have figured out what happened we’ll be busy figuring out a new thing that is happening. First, we are approaching a very small window of time when the Pole isn’t constantly losing heat, but briefly gains heat from 24 hour sunshine, (and winds have to alter to get rid of the extra heat, for a few midsummer weeks). Second, the El Nino is no more, and a La Nina is rapidly appearing, which will greatly decrease the amount of heat the atmosphere has to get rid of, by sending it north to the Pole. If less heat heads north, what might the effects be?

In other words, the swirl we are seeing may be the last one. One feels a certain melancholy, as if saying goodbye to an old friend.

As this low swings up to loop near the Pole and then falls away towards Siberia I’d like to point out a few things Alarmists seem to miss, in their joy over El Nino effects. (They are pleased because the meridienal flow brings warm air up to the Pole, and slightly decreases the extent of sea ice at the edges. This seemingly, and perhaps only briefly, verifies their theory that the Pole is warming, is in a “Death Spiral”, and the Arctic Ocean will be ice free and absorb so much sunshine that we’ll all suffer terrible consequences.  Why this pleases them I don’t know, but it does.) (Maybe “misery loves company”.)

The problem is that a meridienal flow doesn’t just bring warmth north, but also brings cold south.  There have been snows in places that don’t see much snow, such as Saudi Arabia and Mexico, the past winter. And even when such places melt away the snow in a single day, the “albedo” of snow is particularly gigantic in southerly places where the sunlight is intense. In fact Saudi Arabia reflected more sunshine back to outer space in five minutes last January than the entire North Pole did in the months of December and  January. When this data was plugged into an Alarmist computer model, the government threatened to cut off their funding, (or so I have concluded, perhaps unfairly.)

This last fling of the fading El Nino, with its final low at the Pole, seems to not only be bringing snows to France in April, but even to me, here in New Hampshire in North America. Even if the snow only whitens the landscape for an hour, the amount of sunshine reflected as it melts will make all the “albedo” models change their conclusions, or they would change their conclusions, if the people plugging in the data were allowed to include all the data.

For what its worth, here’s the radar shot of the  snow and sleet  over New Hampshire this morning.

20160426 rad_ne_640x480

And here’s a forecast map of the frost (pink) over Britain, France and Germany tomorrow (Wednesday) morning.

Europe Frost April 27 gfs_t2m_eur_5

The simple fact of the matter is our planet has myriad ways of balancing things out.

The meridienal pattern has also made the arctic stormy, and winds have shifted the sea-ice about and caused much cracking of the ice. Open water has appeared even when temperatures were down at midwinter depths, approaching -40°.  Alarmists like this, as they assume this shows the ice is weak, and will melt more easily in the summer. In actual fact exposing the sea to the cold may warm the midwinter air, but it cools the sea, and also creates more sea-ice.  You see, a lead five miles wide cannot form without piling up five miles of ice at some other spot in the arctic, and at the same time exposing sea-water to freezing, forming five miles of new ice in an area which, if it was protected by a roof of ice, would have formed far less ice. In actual fact, in the past we have seen that a lot of lead-formation (which seems to prefer the Beaufort Sea), actually creates so much extra ice and so cools the waters that the summer melt is reduced, not increased.

Lastly, Alarmists seem to rejoice when north winds flush sea-ice south into the warm tendrils of the Gulf Stream that enter the arctic either side of Svalbard. They are happy because you can see the sea-ice melt very quickly, with satellite views. What they do not seem to calculate is how much colder these currents become, if forsed to melt so much ice, and what effect that may have on the current’s ability to melt the bottom of the sea-ice, when the current gets farther north. Furthermore, the same north winds that bring the sea-ice south to the milder currents are bringing cold air to ruffle the top of the currents, not only chilling the top-most water, but reversing the direction of the topmost water.

Alarmists should hope for south winds between Norway and Svalbard, to hurry the tendrils of the Gulf Stream north. When those waters see north winds, as are blowing now, the Gulf Stream is not being assisted. Its waters are being chilled, and the topmost part of the current is actually blown south, which creates all sorts of interesting turbulence between south-moving surface waters and north-moving depths.  It is not a situation conducive to hurrying warmth north and speeding the melt of sea-ice.

In Conclusion, I’d say the effects of the El Nino are nowhere near as simple as some make them out to be. Already I’ve been proven wrong about some of my assumptions. Who would ever assume increasing the heat in the atmosphere would give Kuwait its first snowfall we have records of?

And, if increasing the heat can increase the snowfall in an ordinarily hot desert, might it not increase the sea-ice in an ordinarily cold sea? I’m not saying it will, but I am being humble and saying I’m not sure the after-effects of the El Nino will decrease the sea-ice extent this summer. In fact I’m betting my nickle that the sea-ice extent minimum will be the same as last year, next September, (and I think anyone who bets more than a nickle is a fool.)

The coming La Nina will decrease the heat. We need to be humble about our certainty (or lack of it) about the effects that will have, as well. If the atmosphere becomes more zonal, than general cooling will make sub-polar regions warmer.

By the way, O-buoy 13 shows moisture is being drawn north through Bering Strait. This will dust the black-ice of the new leads with white snow.

Obuoy 13 0426 webcam

The moisture hasn’t made it further east to O-buoy 14, so new leads near it will still have black ice.

Obuoy 14 0426 webcam

With black ice here and white ice there, can you imagine how difficult it would be to create an “albedo” model that was truly accurate?









ARCTIC SEA ICE –North Pole Dumps On Europe–

I’ll have to be quick today, as work is overwhelming me.

The high pressure that was sitting over Beaufort Sea has shifted southeast into the Canadian Archipelago, and if you follow the isobars you can see it is now working in conjunction with a low just south of Franz Josef Land to create a cross polar flow that exports air into the North Atlantic.

If you follow the isobars backwards you notice the air is being sucked from the snow-cover of Canada, and to a lesser extent from the snow-cover of Siberia, before being exported onto the North Atlantic. Eventually this cold air continues down into Western Europe, where a large upper air trough sits.

Shiver Europe 2 gfs_z500_sig_eur_1

This has brought them very cold temperatures, for late April.

Shiver Europe 1 gfs_t2m_eur_1

And there have even been forecasts that snow will be in the air over Scotland, England, Germany and France this coming week.

Shiver Europe 3 gfs_tot_snow_eur_29(1)

To have snow in late April, even though the atmosphere has been pumped full of warmth by the (rapidly fading) El Nino, is going to put Alarmists in an embarrassing position, for it is hard to talk about Global Warming to a population that is shivering.

In actual fact the El Nino has seemed to create an imbalance, and the atmosphere is always trying to correct such imbalances, and one way it does so is to depart from a zonal flow around and around the Pole, and instead to get loopy, with a meridienal flow that at times comes right across the Pole. This may “warm the Pole”, but farmers to the south are not planting up on the icecap, and instead mutter curses to the south.

The best Alarmists can do is distract, by pointing up to the Pole and exclaiming how “warm” it is up there (though it is still well below freezing and no thawing is occurring).

DMI3 0425 meanT_2016

The problem is that the El Nino is fading fast, and a La Nina is expected. Some models are saying it will be a big one, which will likely lower the earth’s temperatures every bit as much as the El Nino raised it.


Scripps 0423 Screen_Shot_2016_04_23_at_4_17_56_AM

In other words, the climate is moving through a cycle. It always has and always will. CO2 has only the slightest effect. It is not worth spending billions to control weather we can’t control. However it is worth helping farmers replant when frost kills their seedlings for, after all, they feed us.

If you must worry, worry about high food prices; not about the fact sea-ice is a little below normal after a big El Nino. There is still more than twice as much sea-ice as there was six months ago. (On this date, back in 2012 when Sea-ice late reached record lows, (red line in chart below) sea-ice was at normal levels, which shows how much the extent-level matters at this early date.)

DMI3 0425 icecover_current_new (1)


ARCTIC SEA ICE –Warming Ice–

One dynamic that will cross your eyes, if you should have the time to spend attempting to contemplate all its intricacies, involves the warming of the sea-ice before it starts to even think about melting. In fact it is still freezing and getting thicker, as it first starts to warm. That alone sits one backs onto their heels. How can the ice be getting warmer if it is getting thicker?

It is rather simple, when you think that ice at the surface can be down to around -60°C when the bitterest cold howls off Siberia in the deepest dark of January. It is obvious that, should that ice “warm” to -59°C, there is not going to be much melting going on. In fact it can warm and warm and warm, all the way up to -1.9°, and the ice will blithely ignore all the warming and go right on getting thicker.

In fact the words, “warm”, “warming”, and “warmer” can be handy tools, if you own a cruel streak and wish to agitate Alarmists.   Just make your eyes round and clasp your hands and say the ice is heating up, and you’ll get to watch them rush around like chickens after corn.

However I am a kindly old man, and don’t torture people more than I have to, and if I am going to cause anyone a headache I prefer to do it to myself, simply by trying to get my mind around the complexities of what boils down (poor word choice) amounts to an ice-cube melting in a glass of water.

The warmth is coming from both the top and the bottom.  Assuming the ice “remembers” the winter’s cold, and has been chilled to -25°C , you have that temperature sandwiched by “warmer” air of -15°C above, and “warmer” seawater of -1.9°C below.

Keeping that sandwich in mind, it then pays to remember the first and second laws of thermodynamics.

A bit of thought makes it clear that the most warming of the ice comes from below, and in fact has been radiating up all winter, even as the ice has been growing thicker, and continues to grow thicker. Not only does this heat come from the water, but latent heat is released from the water as it freezes. (That’s a hard thing to get your mind around. When water is freezing one seldom extends their palms to feel the warmth radiating from the phase change.)

Eventually the ice, at the bottom, will reach its melting point, and we’ll then discuss the opposite phase change, which gobbles up available heat, turning it back to latent heat. But before we reach that point we run into a few other small problems. First, as the salt water freezes it exudes the salt, which involves a further heat exchange. Then you wind up with fresh water ice sitting in salt water. How is this a problem? Well, the melting point of fresh water is 0°C and the water is at -1.9°C. So how can the ice ever melt?

I’m getting a headache.

In any case, as you look at the maps below please keep all the above in mind.

When we last looked a “Swirl” was laughing at textbooks and sitting on the Pole. Apparently this irritated the high pressure towards Canada, who believes in doing things by the book, and it has been making a noble effort to sit on the Pole.

Now we have nearly achieved the state where high pressure sits on the Pole, and all is as it should be, according to the book.

The only problem is that the low north of Norway looks like it is going to be rude and head straight to the Pole. Besides exporting a lot of cold down towards Europe, (Joe Bastardi at the Weatherbell site points out by April 27 snow might be seen down in France and Germany),

but also this will make life interesting for the tourists up at the Barneo camp. So far the skies remain blue and the huts have been set up.

The airstrip hasn’t cracked lately, and the jets are landing on schedule.

Winds are light, and temperatures, which made it up to -15°C, have dipped back to -23°C, as the base drifts slowly towards Fram Strait, and the various cross country skiers, helicoptered to various points on the Russian side of the Pole, hurry to get to the Pole before the storm comes north.

Things could get interesting up there towards the weekend.
