From storms and cyclones: NOx is able to generate, possibly accompanied by particulate matter.
From wildfires: :fire: the amount of nitrogen oxides increases, fire are large and they usually take a long time to extinguish.
From volcanic eruptions: large amounts of gas mostly composed of sulfur dioxide will emerge, even creating acid rain.
From the phenomenon of heat inversions: usually occurs around the time of the season. Heat inversions create a low - layer mist which causes pollutants in the air to be trapped in the ground - close atmosphere, causing pollution.
