In the last period, thanks to the previous negative NAO and AO phases, old temperature records fell in many coldest parts of continents in Northern Hemisphere.
In Canadian Arctic, frosts up to -46,0°C have appeared, so far – in many regions, it´s the strongest earliest frosts since 2004 /https://mkweather.com/eureka-431c-the-lowest-temperatures-in-canadian-arctic-in-early-winter-since-2004/; https://mkweather.com/canada-460c-daily-records-in-yukon-were-broken//.
In Europe, the strongest early frosts since 1945 have surprised Sweden (-43,8°C) /https://mkweather.com/the-strongest-early-frosts-in-the-baltic-region-in-62-years-since-1959-tartu-estonia-276c-zoseni-latvia-264c//, the strongest early frosts since 1959 Estonia (-27,6°C) /https://mkweather.com/the-strongest-early-frosts-in-the-baltic-region-in-62-years-since-1959-tartu-estonia-276c-zoseni-latvia-264c// and in valleys in continental Europe was measured -22,0°C so far /https://mkweather.com/220c-in-pontets-france//.
All after anomalously cold Arctic, with the 2nd highest Arctic Sea Ice Extent in the last 15 years /https://mkweather.com/arctic-sea-ice-extent-is-the-2nd-highest-in-15-years/; https://mkweather.com/20-vessels-stuck-and-ice-locked-in-northern-sea-route-the-arctic//.
Now, the next breath-taking temperature record appeared in Siberia – in Delyankir, only -59,1°C was on 7. December 2021 measured, which is the coldest December temperature in one of the coldest Siberian cities in all-time history! /https://en.wikipedia.org/wiki/Delyankir/
We should consider this temperature as the strongest early frost in the region ever, and even, in the next mornings, excessive minimum temperatures below -60,0°C are in Yakutsk expected.
Oymyakon reported -56,7°C, so far, but the temperature will be decreasing here, too, maybe we will see soon below -60,0°C.
The December temperature record for Oymyakon has a value of -62,8°C and this temperature was measured in the last December days, around 20 days later than the current date! /https://en.wikipedia.org/wiki/Oymyakon/
Schools in Siberia are closed, people are in the emergency regime and they are prepared for the next extreme weeks, because the winter is forecasted to strengthen maybe until New Year, maybe half-January 2022.
Extremely low temperatures and blizzard in the mountains even appeared in Hawaii in the last days, with the lowest temperature in Honolulu since Winter 1979 /the next Mkweather article/.

La station de #Delyankir dans la région de #Yakutia sur l'Est de la #Russie a enregistré la nouvelle température la plus froide de la saison dans l'hémisphère Nord ce 7 décembre avec jusqu'à -56.6°C. Celle-ci pourrait s'approcher des -60°C dans les prochains jours ! pic.twitter.com/eF0FUJuU5F

Vertical wave fluxes (i.e., poleward heat transport) will be very weak out of Siberia/North Pacific (blue shading in 1st 2 panels). The culprit is lack of any amplified flow over Eurasia and a building ridge over the Bering Sea, shutting down wave activity in this area. 3/ pic.twitter.com/ZZodS9XY8a
