This all depends on how big the city is. or, how many vehicles travel in and out of the city. but probably the main reason is industry. All those smoke stacks everywhere.
Topography, population and industrialization.
For instance an enclosed valley will trap the atmosphere and make a micro climate.
The very existence of pollutants will cause a problem in certain areas.
The amount of pollutants relative to the size of the population will have an effect.

∙ 13y agoSmog is a type of air pollution. Modern smog is a type of air pollution derived from vehicular emission from internal combustion engines and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog. Smog is also caused by large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide.
It is wrong to say that smog usually occurs in cities... now a days smog can be found in everywhere including rural areas. The reason behind to find smog in cities that cities are highly polluted due to the presence of factories, vehicles etc. These elements highly contribute to the creation of smog in cities.
