North Pole is Much Warmer Than Usual

The Washington Post reports that weather conditions at the North Pole are abnormally warm for the beginning of winter.

It's polar night there now — the sun isn't rising in much of the Arctic. That's when the Arctic is supposed to get super-cold, when the sea ice that covers the vast Arctic Ocean is supposed to grow and thicken.

[...] "It's about 20C [36 degrees Fahrenheit] warmer than normal over most of the Arctic Ocean, along with cold anomalies of about the same magnitude over north-central Asia," Jennifer Francis, an Arctic specialist at Rutgers University, said by email Wednesday.

"The Arctic warmth is the result of a combination of record-low sea-ice extent for this time of year, probably very thin ice, and plenty of warm/moist air from lower latitudes being driven northward by a very wavy jet stream."

No one quoted in the article speaks about Global Warming, but they all think the situation in the Arctic is anomalous and are interesting in learning more about its causes.

    From the same image on the WaPo article, Siberia's 20C *colder* than its typical mid-november temperature.

    Fortunately the warm weather in mainland US currently means that it's still cherry-picking season.

    Different area, Alaska, but similar latitudes...

    Says that being ~20C out is a 96th-97th percentile thing, so would be expected about once every 15 years.

    Never trust any graph without error bars or some SD-related bands.

    Klink, let me remind me that there are two fronts in this war, and you can be moved to the other one...

      A warm front and a cold front?
