The following post can give answers to many questions regarding Oymyakon, the Pole of Cold in Siberia. The author of the post is Jordi Marqui, a Catalonian cold weather enthusiast, who has its own WP blog AmazingSnow. The article was initially published on my partner blog ColdUnited.com. Thanks, Jordi!
Talking about Ojmjakon involves talking about the cradle of the cold, at least one of the few cradles of the planet. It is known that the -71.2°C is there, like a record, but probably won’t be satisfactorily demonstrate.
I expose a graph below, courtesy of forum collegue (rs), very involved in monitoring global temperatures, which shows us the detail of the number of days (since 1943) per year that Ojmjakon has reached (even exceeded) the -60ºC. As seen at first sight, and within natural variability, the powerful years to achieve this figure are from some time ago, with the decade 1985-95 as the least conducive to these rigors. In recent years, since 2000, seems to appear the 6 again, not with the frequency of periods that are obvious in the graph, but not staying at an impossible figure as in the aforementioned decade.
Below, temperature record of the last two winters
and
Let’s look the maps at 850 hPa for the days when the amazing mark appears. We had this temperature at 850 Hpa those days, equivalent to an altitude of 1,500 meters above sea level (approximately) and where the pressure of the atmosphere is that, 850 hPa. As we can see, the area appreciates bags about -40 º C, temperature which is difficult to see during the winters, this cold, with anticyclonic calm, is a sufficient condition for cold brands of this caliber in appropiate areas like Ojmjakon.
If we go from 1.500 meters to the 745 msm (meters above sea level) of Ojmjakon, and those which are in the area of Eastern Siberia, we found these temperatures for January 19, 2008. Ojmajkon is in the highest step of the podium, while, in neighboring areas, -50ºC are also outdated.
The following winter, for the same 2008, two appearances of -60, with similar cold air bags swarming the colder region of Siberia.
The surrounding areas also reflect the strength of the cold, and surrounding areas already reaching the -55 ° C
Year 2008, three days below -60ºC, 22 December the coldest day, with an average for the 24 hours of -58.3°C.
Finally, remembering the recent calendar, a day in 2002, when the -65°C were a stone’s throw. The -71.2ºC is not far away. Unbelievable.
