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.
We differ primary pollutants like nitrogen oxide, volatile organic compounds, and sulfur dioxide, which is made by motor vehicles and some industrial processes (power plants) and released in the atmosphere. Secondary pollutants are made from the primary pollutants in the presence of UV light.
Factors that contribute to smog formation are the high temperature (direct effect), sunshine (UV light), calm wind an heavy traffic (release of air pollutants in the atmosphere).
