The atmospheric stability and a smoke plume shape – Fumigation

The smoke plumes are blocked by inversion, pollution reaches the earth’s surface. This situation occurs when the ground-level atmosphere is unstable and there is a stable atmosphere just above the chimney outlet, associated e.g. with temperature inversion. The smoke plumes then remain in the area of unstable atmosphere. The concentration of pollutants is high at a distance of about 1-1.5 chimney height. THE MOST UNFAVORABLE SITUATION!!!
