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.
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.
