http://www.wunderground.com/global/stations/WUHMP.htmlPevek is located at Lat/Lon: 69.8° N 170.6° E -- it's the coastal town at the southern point of the Siberian Sea, the area in quesiton. The temperatures there have been unusually high for the last few days -- up around 20°C/70°F. I would guess it's a poleward flow of warm air from a high pressure cell over northern China, also having some warm days.
And the heat wave is expected to break, I see.
It's also been warmish in the Alaskan-Canadian Arctic, and in west Greenland. Adjacent Ellesmere Island is enjoying a rare thaw.
I initially saw this on
Athropolis. If you click on their map, you get short weather items from all around that area. Looking around, the Arctic is having a very weird summer. Weirder than the normal Arctic weird. Lots of smoggy fog and
pogonip (ice fog) is being reported. Smog tends to accumulate up there, but it's been especially bad in the past few years.
Meanwhile, much of the area between Greenland and Scandinavia is still sub-freezing. Any speculations on how the North Sea thermohaline circulation is faring?
"Faster than expected." That's our new climate mantra. Ketchy, innit?
--p!
P.S. --
I have not been on line as much lately. "Other priorities" have been taking up my time, as my nuclear master Dick might say. (I got a medical card, and have been using it.) But I do check in from time to time to read the news and keep up with the situation in the Arctic. And that's getting too unnerving to contemplate on a daily basis.
There was also a bad ("once-in-a-brazillion years") winter storm in Australia recently, and some major upset in the oil biz over refinery capacity, though that might be more of the usual dog-'n'-pony show.
Ah, the Holocene. It was nice while it lasted.
