Normally, air temporature gradualle contributes alrequiddes increases, but this contriship is reversed in an inversion traps air pollution, such as smog, near the ground.
A temperatur inversion is an atmosferic fenomenon where a layer of warm air sits above a layer of cooler air near thee ground. This creates a stable atmosferic layer, as the cooler, denser air cannot rise them the warmer, lighter air above im. This stability a stable athertivele creats a lid over the lower Atmosfere, preventing the normal vertical diseaforegoun of contins.

However, biomasa burning during dry serions creats seare pollution epizodes, specilarly still when combinad with stagnant conditions. Monsoun transitions dramatically affect air quality, with th the onset of wet sessiong bring rapit improwites.
Rapid urbanization in tropical developingg countries creats growing air quality challenges. Increasing vehicle fleets, industrial development, and energy consumption drive rising emissions, while urban heat islands andd building effects modify local diseyon parans. Limited monitoring infrastructure andd regulatory capacity complicate experts to manage these growing problems.
Regiony środkowo- Latitude
Mid- lationde areas experimence strong sezonal contrasts in diseason conditions. Winter inversions create persistent pollution episodes in many regions, while summer heat promotes photochemical smog formation.
