Central Siberia, -53,0°C: The coldest March temperatures in history, La nina brings colder Spring, but hot Summer 2021

Extreme air, which bothered Europe in February 2021 has shifted above Siberia and from central Russia are still reported extremely low temperatures – with spring temperature records.

In Tutonchany, central Siberia, minimum temperature dropped to -53,0°C, what is the coldest in March since measurements began (1959) and in Tura, -50,7°C was measured, what is the lowest temperature since 1928 (the start of measurements).

Much of Russia reported winter 2-4°C below 1961-1990 normal and February 2021 6-8°C below normal. After milder the first half of Winter 2020/2021 has come one of the coldest periods in Russia in modern history.

Into peak of La nina during last months /https://mkweather.com/the-coldest-earth-for-7-years-strong-impact-of-la-nina-is-here/; https://mkweather.com/la-nina-in-australia-the-coldest-summer-in-9-and-the-wettest-in-4-years// now has entered the next factor, favorable for colder global conditions – eruption of Mt. Sinabung in Indonesia /https://mkweather.com/additional-contribution-for-global-cooling-sinabung-erupted// and it appears, that La nina together with big stocks of cold Siberian air should bring during the next months additional spring coldwaves around Northern (and Southern Hemisphere too).

However, many La nina years, e.g. 2012, has brought hot summers, too, thanks to persisting NAO-/AO- phases, which are linked in summer with higher probability of extreme heatwaves such as stabilizing NAO+/AO+ phase (during NAO-, strong pressure trough up to Azores and Northern Africa initiate Saharan advections above Europe, while during NAO+ in summer, colder and drier air from NW Europe is flowing above continent).

After colder winter and spring than usual therefore we should be prepared for hot Summer 2021.
