MAIN WEATHER AND CLIMATE TRAITS IN THE NORTHEN HEMISPHERE AS OF SEPTEMBER 2022
Air Temperature
With the first days of autumn after abnormally hot August, cold weather came to the ETR. Numerous minima of daily temperatures were recorded in the west and centre of Russia. Negative temperatures were measured for the first time in a number of locations, and frosts were observed in many areas. The average air temperature in the first decade was 2-4 or more degrees lower than normal. Later on, the temperatures approached the normal values, but negative anomalies still prevailed there until the end of the month. In Central Russia and in the Urals, the average air temperature in September was about the same as in the previous year.
Air temperatures in Siberia fluctuated around the normal value in the first half of the month, but the weather in the third decade became noticeably colder, and the decade-averaged temperatures turned out to be 2-3° lower than usual. In the Far Eastern Federal District, temperatures remained normal almost for the entire month, although in Buryatia and in the south of the Khabarovsk Territory, the weather was excessively hot at the beginning of September: there, the unprecedented values reaching 25-30° or higher were recorded.
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.
