Published 10.08.2021 Since the middle of the first decade of August 2021, a high-altitude cyclone has been located over the territory of Western Siberia, which contributed to the transfer of air mass from the areas of Yakutia where forest fires occur to the south of Western Siberia (Fig. 1-2). In the future, the plume of smoke from forest fires gradually spread to the north-eastern regions of Kazakhstan, where local steppe fires (East Kazakhstan Region) additionally contributed to the deterioration of atmospheric air quality (Fig. 3).
For August 09-10, 2021, in the territory of the East Kazakhstan region, the excess of the maximum permissible norm in atmospheric air was recorded for nitrogen dioxide in the cities of Ust-Kamenogorsk up to 2.1 MPC; Semey up to 1.4 MPC; sulfur dioxide in Ust-Kamenogorsk up to 9 MPC, hydrogen sulfide in Ust-Kamenogorsk up to 5.0 MPC.
According to the forecast, unstable weather is expected in the coming days, there will be rains, heavy rains in some areas on August 12-13, with thunderstorms and gusty winds. It is predicted that the air temperature will gradually decrease at night to 10 ... 18 degrees Celsius and during the day to 15...23 degrees Celsius.
Meteorological conditions will contribute to the dispersion of pollutants in the air basin of the region.
