MAIN WEATHER AND CLIMATE TRAITS IN THE NORTHEN HEMISPHERE AS OF AUGUST 2022
Air Temperature
Hot weather that persisted in the central and northern regions of the ETR at the end of July spread to almost the entire ETR by the beginning of August. The air temperature in the central region reached 30-35°, and the anomalies of decade-averaged temperatures in the first decade amounted to 2-4°. In the following days of the month, the weather became even hotter. New temperature maxima were recorded in the ETR areas from the Kola Peninsula to Kalmykia. Sometimes, the air temperature exceeded +40° in the south, and rose to +25° and above in the polar regions in the north. The anomalies of decade-averaged temperatures topped +5-8°. So this August was ranked the hottest in the entire history of meteorological observations in the whole ETR and in the North-Western Federal District, the second hottest in the Central Federal District, the third and fourth hottest in the Southern and Volga Federal Districts, respectively, and the fifth hottest, in the North-Caucasian one. In 2022, August in the ETR was warmer than July.
The situation was quite different in the Urals and to the east of them where abnormally cold weather prevailed for most of the month. Daily temperature minima were set in Chukotka due to the frosts as low as -3°. Frosts were also observed in the south of the Urals and across many regions of Siberia. The weather was abnormally warm along the Arctic coast only.
Regarding Russia in overall, this August became the fifth warmest in the meteorological annals since 1891. The monthly-averaged temperature was 2-5° higher than normal everywhere from the western border to the Urals, and along the coasts of the Arctic seas. In most of the Siberian Federal District and in the western regions of the Far Eastern one, negative anomalies of at most 1.0-1.5° took place.
MAIN WEATHER AND CLIMATE TRAITS IN THE NORTHEN HEMISPHERE AS OF JULY 2022
Air Temperature
The heat that spread over the north-west of Russia at the end of June still persisted there in the first decade of July. New daily temperature maxima as high as 30° and above were set in Karelia and in the Leningrad and Pskov Regions. Very warm weather came to the central and southern regions of the ETR as well, and new unprecedented maxima were also recorded in the Smolensk and Kaluga Regions as well as in the Krasnodar Territory. Yet, cold nights with new record-breaking minima were observed at the same time in the Arkhangelsk Region and the Komi Republic in the north.
In the second decade, cool weather with the temperatures either close to or somewhat lower than normal prevailed over most of the ETR but was defeated by warmth in the north where new positive extremes were recorded in some places. As for the third decade, the temperatures noticeably above normal persevered in the north and came back to the central regions again.
In the Urals and in Siberia, the weather oscillated between abnormally warm and cool. It was very cold at the end of the second decade in the south of Western Siberia: there, new temperature minima were even recorded in the Kemerovo Region. But eventually, the monthly averages of air temperature in this area were close to normal.
