Air quality in Tashkent: possible improvement on the morning of November 15

On the night of November 15, air quality in Tashkent may change. According to forecasts, in the evening hours air quality on the International Air Quality Index (AQI) is initially expected to be at a "moderate" level, and from 21:00 until morning at a "unhealthy for sensitive groups" level. According to the National Air Quality Index, the city average indicator may be mostly at a "green" level, and at certain times at a "yellow" level possible.

 

It is noted that a drop in air temperature at night, very weak wind and a strong temperature inversion will limit air exchange in the lower layers of the atmosphere. These conditions weaken the dispersion of emissions and PM particles formed in local and neighboring areas and create conditions for them to remain in the layer near the earth's surface.

 

According to forecasts, in the morning hours of November 15, the weakening of the inversion will improve air quality. By 10:00, air quality may drop to a "moderate" level on the International AQI and to a "green" level on the national index.
