Smog A word currently used as a synonym for general air pollution. It was originally created by combining the words "smoke" and "fog." ...
Smog
Smog (contraction for 'smoke fog') is a fog in which smoke or other forms of atmospheric pollutant have an important part in causing the fog to thicken, and have unpleasant and dangerous physiological effects.

Smog
Smog - contraction for 'smoke fog'. An unpleasant fog in which smoke or other atmospheric pollutants (sea spray, dust) have an important part in causing the fog to thicken.

SMOG: Pollution formed by the interaction of pollutants and sunlight (photochemical smog), usually restricting visibility, and occasionally hazardous to health.
Smog: Originally a combination of smoke and fog, this term is now used to describe mixtures of pollutants in the atmosphere.
Smog- a mixture of smoke and fog; a natural fog contaminated by industrial pollutants.
Stable Air- air with little or no tendency to rise, that is usually accompanied by clear dry weather.
Smog Originally smog meant a mixture of smoke and fog. Now, it means air that has restricted visibility due to pollution or pollution formed in the presence of sunlight--photochemical smog.
Smog
Fog having a high pollution content.
Snow
Precipitation of ice crystals, isolated or agglomerated, falling from a cloud.
smog—A mixture of smoke and fog.
smoke—A restriction to visibility resulting from combustion.
snow—Precipitation composed of white or translucent ice crystals, chiefly in complex branched hexagonal form.
Smog- Air pollution caused by a mixture of smoke and fog.
Snow- Precipitation consisting of clumps of ice crystals.
Solar Energy- The energy produced by the sun.
Smog - It's visible air pollution in urban areas. It looks like dirty fog in large cities.
Photochemical Smog
Air pollution containing ozone and other reactive chemical compounds formed by the reaction of nitrogen oxides and hydrocarbons in the presence of sunlight.
Photosphere ...
Photochemical smog Air pollution produced by the interaction of ultraviolet light, nitrogen dioxide, and hydrocarbons; produces ozone and PAN through a series of complex photochemical reactions.
Photochemical Smog A type of smog that forms in large cities when chemical reactions take place in the presence of sunlight, its principal component is ozone.
It is also a primary component of smog.Ozone holeA thinning of the ozone layer over Antarctica, which occurs each spring.Partly cloudySky condition when between 3/10ths and 7/10ths of the sky is covered. Used more frequently at night.
smog Air pollution associated with oxidants. smoke Particles suspended in air after incomplete combustion of materials. soil carbon A major component of the terrestrial biosphere pool in the carbon cycle.

haze"Particles suspended in air, reducing visibility by scattering light; often a mixture of aerosols and photochemical smog. Many aerosols increase in size with increasing relative humidity due to deliquescence, drastically decreasing visibility.
The Ozone Season During the warm season in North America, stronger sunlight and heat combine to convert industrial and transportation emissions into smog (ground-level ozone). This is particularly true for major metropolitan areas.
With the help of the sun produces "Photochemical Smog". 11. OZONE: Ozone does not penetrate deep into the ocean. 12. OZONE: Ozone Hole forms in the Arctic, however it is much smaller. 13. OZONE: OZONE HOLE phenomenon first observed in 1980s 14.
Near industrial areas, fog is often mixed with smoke, and this combination has been known as smog. However, fog droplets are usually absent in photochemical smog, which only contains unactivated haze droplets.
Nitrogen oxides are typically created during combustion processes, and are major contributors to smog formation and acid deposition. NO2 is a criteria air pollutant, and may result in numerous adverse health effects.
condition in which a layer of warm air, usually from a high pressure system, moves over a colder layer, preventing it from rising or dispersing. In urban areas, automobile and industrial air pollutants become trapped, resulting in a band of smog from ...
It is formed in the upper atmosphere through the dissociation of oxygen molecules by solar radiation. In the lower troposphere, it is a pollutant which characterizes photochemical or Los Angeles-type smog.
Such a lapse rate causes air to sink and may prevent any convective activity (subsidence). Sometimes inversions prevent mixing at low levels causing smog and pollution to be trapped beneath it, common in Los Angeles, California, for example.
Ozone - A form of oxygen in which the molecule is made of 3 atoms instead of the usual two. Ozone is usually found in the stratosphere, and responsible for filtering out much of the sun's ultraviolet radiation. It is also a primary component of smog.
this type of fog is a reduction in visibility, which may drop to as low as 10 feet in thick fog. If visibility is between 0.5 and 1.25 miles (1 and 2 km), the fog is known as mist. If any smoke is present, it may combine with the fog to produce smog.
