There are temporary weather occurrences that can affect the weather, such as a storm or an earthquake. Along with that, pollution is a major factor in the change in air quality. Different things in the air like smoke and chemicals can heavily impact the air quality.

Various things may affect the air quality index. The topography is one of the reasons.
