Disadvantages of inversion

The most obvious disadvantage brought by inversion is air pollution.

No matter what causes the inversion, it will have a great impact on air quality. It hinders the vertical convection of air and the diffusion of smoke, pollutants and water vapor condensate. Tens of meters or even hundreds of meters thick inversion layer covers the city like a thick quilt, and the pollutants near the ground have no way to go, so they have to "stay where they are" and accumulate more and more, and the smoke will cover the sky and the air pollution will inevitably increase. At the same time, air pollution poisoning incidents are mostly related to inversion. If inversion occurs for several days, air pollutants will accumulate in large quantities, which is prone to air pollution poisoning. For example, in the industrial town of Donola in the United States, 1948+00, the temperature reversed for four consecutive days in June, and the air pollutants sulfur oxides and smog emitted by factories and residents could not spread in time, so that in this small town with only 14000 people, 5900 people fell ill and more than 20 people died within four days. 1952 The smog event in London, England was also related to fog and inversion. Smoke and sulfur dioxide emitted by factories and thousands of households stayed above the city, and 5000 people died in four days. The smog event in Mas Valley, Belgium and the optical smog event in Los Angeles are all related to the inversion weather.
