Cold anticyclone in Uzbekistan worsens air quality
Starting today, a cold anticyclone is entering the territory of Uzbekistan. This was reported by Zamin.uz.
This may lead to a deterioration in atmospheric air quality. The main problem is that air circulation may slow down and temperature inversion may occur.
In this situation, pollutants may not rise but accumulate near the ground layer. Currently, meteorological conditions that enhance temperature inversion are being observed in the region.
During the day, a sharp temperature difference, namely +5...+7 degrees at night and +16...+18 degrees during the day, will further intensify this process. Since Tashkent city remains under the influence of moist and cool air masses, fog, high humidity, and almost windless weather are observed in the early morning hours.
This slows down air exchange, causing waste and smoke to remain longer in the urban area. Usual pollutants may accumulate in the city.
The main sources of these pollutants are vehicle emissions, heating systems, and industrial waste. When air movement is slow, the concentration of dust and fine particles is likely to increase.
This can cause discomfort on some days, such as sky haziness, difficulty breathing, or noticeable odors. Experts emphasize that such a situation may persist for the next three days.
By March 10, the cold anticyclone is expected to fully cover the region. Later, the situation may ease, meaning air temperature will stabilize, wind speed will increase, and precipitation may clean the atmospheric air.
Thus, the upcoming days will be a test period for the air, and after March 10, the situation may improve due to wind and precipitation. Source: One.uz.
