Smoke and fog
Smoke and fog
smog = Smoke + fog it is created when the fog mixes with the pollution in air. Smog looks almost like fog, but is harmful if inhaled for a sufficient period of time.
The "short" answer is- Inefficient combustion in the vehicle's engine produces chemicals that when exposed to sun-light create smog.
There are two major types of smog: photochemical and industrial smog. Photochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form particulate matter and tropospheric ozone. The air pollutants that are most responsible for this type of smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs). Photochemical is especially a problem in areas with many cars, coal-burning power plants, and the right weather conditions. Los Angeles, CA is a city that often has to deal with photochemical smog.
Summer because photochemical smog is created by the actions of sunlight on pollutants, and sunlight is stronger in the summer than winter.

Smog, is the scientific word, for the combination of smoke and fog.
Heterogenous. Not all smog is created equal. In New York City, for example,smog on the FDR drive during rush hour may have a different chemical composition from smog directly near the electrical generation plant ( more carbon, more perticulates etc.).
