Answer

Photochemical smog is formed from the air pollutants such as nitrogen oxide, in the presence of ultraviolet sunlight. Thus, it is usually present in the warm and densely populated areas, in the morning and afternoon hours. A brown haze is formed in the air of the polluted areas which comes from the color of nitrogen oxide. Factors that contribute to smog formation are the high temperature (direct effect), sunshine (UV light), calm wind and heavy traffic (release of air pollutants in the atmosphere).
