| The Effects of Meteorology and Geographic features of the region on smog creation | ||||||||||
| The three main meteorological factors that influence the formation of photochemical smog are: * Precipitation, which can alleviate photochemical smog as the pollutants are washed out of the atmosphere with the rainfall. * Winds, which can blow photochemical smog away, replacing it with fresh air. However, low lying areas, such as valleys can receive the pollution. * Temperature inversions, which can enhance the severity of a photochemical smog episode. |

| Geographical features (topography): Communities situated in valleys are more susceptible to photochemical smog because hills and mountains surrounding them tend to reduce the air flow or atmospheric transport, thus allowing for pollutant concentrations to rise. | ||||||||||
