ARCTIC SEA-ICE –Arctic Africa–

One thing I have learned from Alarmists is the effectiveness of distraction. When you have completely blown a forecast, it is helpful to point at something happening far, far away.

Therefore you will not notice that I am six days away from the date I assigned for the jet stream to stop being loopy. You will forget I stated the polar flow would become zonal on February 13, due to the lagged effect of the La Nina. You will forget….  You will forget… You are getting sleepy… Very sleepy…

What the heck? It’s not working on you! Oh, I forgot. That only works on Alarmists.

In any case, a second mild surge as good as last winter’s second surge has made it to the Pole.

DMI5 0207 meanT_2018

I haven’t time to go into all the details. In a nutshell it is a surge “madoki” (Japanese for “the-same-but-different”), because (so far) it took a less direct route than last year. Rather than, like last year, roaring straight north from the Atlantic, the surge dented east over Norway and only turned north over the Kara Sea. Consequently the temperatures, on a whole, have been colder than last year’s. But that is basically straining at gnats and quibbling over piffling details. The fact of the matter is that precisely where I thought high pressure should build and form the core of a nice zonal flow (which may be wish-casting, for it would give me, down in New Hampshire, a milder winter), what to my wondering eyes should appear, but “Ralph”! (An anomalous area of low pressure at the Pole.)

 

 

To have “Ralph” reappear, when I have been putting the finishing touches to his obituary, is a sign I’m having a bad week. (It was bad enough that the hero quarterback got strip-sacked at the crucial moment, and the home team lost the Superbowl.) (Furthermore, New Hampshire is not getting the sort of mild weather I wanted.)

The problem with mild air heading up to the Pole is that it displaces the cold, which comes south one way or another and gives arctic conditions to people not prepared for such nonsense. Because this post is suppose to be about sea-ice, I’ll mention the fish-farmers on the coast of China.

But I also need to mention the Sahara, because there is something that just tickles my sense of humor about bringing Africa into a sea-ice post.

But mentioning Africa is a bit odd, as I have noticed that the phrase “one every fifty years” doesn’t sound quite right, when you use it twice in three years. I noted that oddity, when writing about the January snows along the Algeria-Morocco border three weeks ago. But now we are talking about snows along that border twice the same winter.

There are some high north-African mountains, the “Atlas”, that get snow every winter, and send precious melt-waters down to the Sahara from the north, but ordinarily these snows stay up by the clouds. It makes news when these snows spread down to lower altitudes. (The translation of the first video is, “After more than fifty years…The snows in Zagora”).

The translation for the second, longer video is, “Today: After more than 50 years…The snow in Zagora and the south-east of the Kingdom.”

At this point I need to bring up the magic word “Albedo”, which Alarmists feel is very important in discussions of sea-ice. Basically it involves sunshine that could warm our planet being bounced away by the whiteness of snow. Alarmists have suggested that less sea-ice at the Pole could allow “run away warming”. But what about snow on the northern fringes of the Sahara? The sun shines brightly there in February, while it will not shine at the Pole until the Equinox. Is there any chance all the heat lost in the Sahara could cause some sort of “run away cooling”?

Crickets.

(In any case, such a focus on the Sahara is an excellent deflection away from my forecast for a zonal arctic-flow by February 13.)

One of the most annoying aspects of a loopy (or “meridional”) flow occurs when you happen to find yourself at the place where the warm air looping north battles with the cold air looping south. In some ways it is better to endure the cold, for cold tends to be dry. When you sit on the border you can get excessive amounts of snow. For example, the core of the cold sank down in Eurasia at the end of January, and Moscow, well to the west of the worst cold, has been afflicted by Atlantic air streaming east past Norway even as arctic air streams west further south. They have had amazing amounts of snow. During the first week of February they broke their snowfall records for the entire month of February.

This clashing between colder and milder air has been annoying on my side of the planet as well, for even with the core of the cold elsewhere we can get unfair amounts of glop. I’d prefer pure, Siberian cold, for powder snow is easy to shift, and when the cold gets really cruel the old timers say, “It’s too cold to snow.”

In New Hampshire, this winter has been pleasing to Alarmists, I suppose, for the arctic retreated after the first week in January, and since then temperatures have been around seven degrees above normal. This doesn’t really thaw us, for our average temperature is 20°F (-7°C), and “mild” only lifts us to 27°F (-3°C). However an average of 27°F does allow for daily highs to creep above freezing, and does allow snow to turn to sleet, freezing rain, and brief episodes of all-out rain, which creates slush as heavy as mud.  You must shift this heavy glop from walkways and drives, or it swiftly freezes harder than iron. (I’ll take shoveling powder snow any day.)

Nor does all the glop make lake-ice thinner. Wet, heavy snow on ice pushes the ice down, and water oozes up through cracks and turns the snow to slush. It takes little (just a cold, starry night), to turn that slush to solid ice, as, being ice-water, it is right at the freezing point. Then, besides the original two feet of ice that the bitter cold of early January created, you have an additional two feet of ice created by “milder” temperatures, and frozen slush.

The ice is now so thick on lakes that crazy young men are having races with vehicles and motor cycles that have scary wheels with steel teeth. The churning, spinning wheels chip away a foot of the ice on the corners of the tracks, but nobody seems very nervous about chewing through to water.

I know that lake-ice is not the same as sea-ice, but I thought it interesting that “milder” weather brought snow that turned to slush that turned to ice, and therefore “milder” made the ice a foot or two thicker than it might be if it stayed cold and dry.

Of course, some people never get out of their offices, and don’t understand such counter-intuitive things. There is much to learn from simply hiking about lakes, especially reservoirs that rise with rains and thaws and sink when the dry cold returns. I have young Climate-scientists studying local lake-ice, and am eagerly awaiting my government grants and money from Big Oil.

Of course, insurance companies, in their warm offices, do not approve of such research. They fear “risk”. They want everyone to stay indoors. However they must allow a few out, called “adjusters”. A parent of a child I cared for was such an “adjuster”, and told me a tale that I think typifies the difference between the “indoors” and the “outdoors” mentality.

Today was a typical “glop” day, starting with a quick dump of six inches of snow, which makes things look like a Norman Rockwell painting.

However then the rot set in. The snow sped up, falling faster, and abruptly turned to rain, though temperatures were still well below freezing. Because Moms driving home from work do not have scary wheels with steel teeth, insurance adjusters get called out a lot when the driving stinks.

Now this should give you an inkling of the office mindset, in this corner of the insurance world: If you had to send a fellow out into abysmal driving conditions, what would you reduce your profit by paying for? Snow tires? Or a tattle-tale gadget that keeps track of your adjuster’s GPS and road-speed. If you answered “snow tires”, you are sane, and don’t work in this particular front office.

On a day like today an adjuster received an irate phone-call from his boss. “What in blue blazes are you up to?” the boss inquired.

“What are you going on about?” replied the adjuster.

“You’ve been going 110 mph! Are you crazy!”

The adjuster stayed calm. “Did you check the GPS?”

“Um…no…”

“Check it.”

After a pause the boss muttered, “Oh.  Um…you’re in your driveway?”

“Yes, and do you think I can get the company van going 110 mph (177 kph) in my driveway?”

“Hmm.  Probably not. So…..were your tires spinning?”

“Of course they were spinning! And will you puh-leeze requisition snow tires for the company vans?”

“Oh, no! The stock-holders demand a profit! And we expect our adjusters to know how to drive in the snow.”

Case closed.

COOL PICTURE—3 ECLIPSES

Cool Picture BusySun_slifer_960

It seems to me that some pictures deserve to be passed around the web. This picture by Doyle Slifer is one of them.

Three objects are eclipsing the the sun. First is the small airplane. Second is the streams of clouds. Third is the moon. (There is a fourth thing you can’t see; namely, specks of dirt on my computer screen.)

Above and to the left of the small plane is a group of sunspots on the surface of the sun itself.  As the sun rotated, these large sunspots swung around and pointed right at the Earth, in some ways like the barrel of a gun. There is always the possibility the spot will shoot a solar flare right at us, which can mess up our electronics in various ways.  A flare measuring “X-17” knocked out the electricity in Sweden in 2003. So far the largest this family of spots has produced is an “X-1”, and I think the nervous will exhale in relief as this swings away from us and vanishes around the backside of the sun. By the time the sun rotates around again the spots will likely be gone, or greatly reduced.

This group of spots are the largest of the current cycle, and demonstrate that even a “Quiet Sun” can occasionally make a big group. In some ways this is annoying, for once you get back in history our only records of sunspots are those that can be seen with the naked eye.

In the pre-telescope-era records from China, (the records somehow preserved from the zeal of the Red Guard, during Mao’s insane attempt to erase the past with the “Cultural Revolution”,) there are records of sunspots so large they were clearly seen when the sun was a low, orange disc, partially obscured by dust. Some assumed these historical events hinted at very active sunspot cycles,  but now we see they can occur during quiet times.

 

SIBERIAN SNOWCOVER OFF TO A FAST START

One of the first things I checked when I got back from my trip was the snow-cover in Siberia. I got a bit of a shock.  It usually doesn’t expand this quickly.

What Siberia does, once the nights are longer than the days, is to lose heat. This process is enhanced by snow, which increases the amount of radiational cooling. As this cold builds it sinks, creating high pressure which becomes a semi-permanent feature over Siberia, especially over the east.

Siberia tends to export cold air in all directions, but one needs to pay attention to the weather patterns, and attend to the direction the largest amount of air is exported to.  China suffers when the air pours south, and Europe suffers when the air is shunted west. When the air rushes east it fuels huge north Pacific gales, However when it spills north out over the Arctic Ocean I worry, for then North America is at risk.

Air pours north every year, which is why the Laptev Sea is the largest “contributor” of sea-ice. Ice forms, and then is blown away from shore and out into the Arctic Basin. The amount can vary greatly. Some years produce four times as much ice as other years. It all depends on the outflow from the Siberian High .

Last year a cross-polar-flow developed and took the long route across the center of the Pole.. This actually allows the air to “warm” as it crosses the sea, from minus 70 to minus 30.However as the air starts moving over Canadian tundra it again starts losing heat.

The worst-case-scenario involves the Siberian air taking a shorter route, crossing less ocean by moving from Siberia to Alaska just north of the Bering Strait. This occurred during the very cold winter of 1976-1977, and is what I fear may happen this year.

(I should add that during the summer before 1976-1977, There were Pacific hurricanes that came up the west coast of Mexico and gave Arizona rain, as has happened this year.)

SUMMER SNOWS IN CHINA

SUMMER SNOWS IN CHINA

It has been a hot summer in China. Even today (August 17) it got up to 97 degrees Fahrenheit in Beijing. (36 Celsius.) Therefore, when a vigorous cold front hit the north, and someone posted pictures of the snow, the pictures went viral:

http://www.china.org.cn/environment/2013-08/15/content_29727296.htm

How soon we forget.  People were grumbling when it snowed in China on June 21.

It reminds me of the old ryhme:

When it is hot
We wish it were not
But when it is not
We wish it were hot.
