Mumbai Smog...conditions due to " Air Inversion"
This is when a layer of cooler air is trapped near the ground by a layer of warm air above the surface. When the air cannot rise, pollution accumulates near the ground, leading to higher pollutant concentrations
The warm air above cooler air acts like a lid, suppressing vertical mixing and trapping the cooler air at the surface. As pollutants from vehicles, fireplaces, and industry are emitted into the air, the inversion traps these pollutants near the ground, leading to poor air quality.
