Question

Quizplus · Accepted Answer

Subsidence inversions are mainly caused by high-pressure conditions. High-pressure systems feature a sinking air motion that makes the air in the atmosphere compress and warm up, which prevents the rising of the air and the dispersion of pollutants. This warm and dry air layer creates an inversion where the air temperature increases with altitude, trapping any pollutants below it.
