Detailed explanation-1: -The warmer air rises and acts as a lid trapping the colder air close to the ground. Pollution, including that from road traffic is also trapped, so the air layer closest to the ground becomes more and more polluted. This continues until the prevailing meteorological conditions change.
Detailed explanation-2: -Surface temperature inversions play a major role in air quality, especially during the winter when these inversions are the strongest. Pollutants from vehicles, wood burning, area sources, and industry become trapped near the ground during inversions, leading to poor air quality.
Detailed explanation-3: -An inversion can prevent the rise and dispersal of pollutants from the lower layers of the atmosphere, because warm air above cooler air acts like a lid, preventing vertical mixing and trapping the pollution material e.g. at the breathing level.
Detailed explanation-4: -A temperature inversion is a layer in the atmosphere in which air temperature increases with height. An inversion is present in the lower part of a cap. The cap is a layer of relatively warm air aloft (above the inversion).
Detailed explanation-5: -Effect. Temperature inversion determines the precipitation, forms of clouds, and also causes frost due to condensation of warm air due to its cooling. Dust particles hanging in the air: Due to inversion of temperature, air pollutants such as dust particles and smoke do not disperse on the surface.
