How does a temperature inversion affect air pollution?
Atmospheric Effects. Temperature inversions affect air pollution because they change the dynamics of air movement. Warm air rises in the atmosphere because it is less dense and, therefore, more buoyant than the cooler air above it. This smothering effect traps air pollutants and allows their concentrations to increase.
Inversions occur during the winter months when normal atmospheric conditions (cool air above, warm air below) become inverted. Inversions trap a dense layer of cold air under a layer of warm air. The warm layer acts much like a lid, trapping pollutants in the cold air near the valley floor.
- It almost always refers to a "temperature inversion", i.e. an increase in temperature with height, or to the layer ("inversion layer") within which such an increase occurs. An inversion can lead to pollution such as smog being trapped close to the ground, with possible adverse effects on health.
- When a triad is played on the piano keyboard it can be represent in three positions; the root (or original), 1st inversion and 2nd inversion. When a chord is made of four notes, that specific chord can be inverted three times. The chord in its original position is not included.
- The lapse rate of nonrising air—commonly referred to as the normal, or environmental, lapse rate—is highly variable, being affected by radiation, convection, and condensation; it averages about 6.5 °C per kilometre (18.8 °F per mile) in the lower atmosphere (troposphere).
temperature inversion, condition in which the temperature of the atmosphere increases with altitude in contrast to the normal decrease with altitude. When temperature inversion occurs, cold air underlies warmer air at higher altitudes.
- Inversion, also called anastrophe, in literary style and rhetoric, the syntactic reversal of the normal order of the words and phrases in a sentence, as, in English, the placing of an adjective after the noun it modifies (“the form divine”), a verb before its subject (“Came the dawn”), or a noun preceding its
- Lapse rate is the rate at which Earth's atmospheric temperature decreases with an increase in altitude, or increases with the decrease in altitude. Although this concept is most often applied to Earth's troposphere, lapse rate can be extended to any gravitationally supported parcel of gas.
- In other seasons or weather conditions, warm air sits near the ground and the air can rise easily and carry away pollutants. In a temperature inversion, cold air is trapped near the ground by a layer of warm air. The warm air acts like a lid, holding these substances down.
One of the most harmful effects of inversions is that they trap the pollution close to the ground, trapping the smog. When there is a temperature inversion, the affect is just the opposite.

- Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of Oil spill may lead to death of several wildlife species. 2. Human Health : The decrease in quality of air leads to several respiratory problems including asthma or lung cancer.
- These steps, as well as many others, are things we all can do to help reduce air pollution.
- Conserve energy – remember to turn off lights, computers, and electric appliances when not in use.
- Use energy efficient light bulbs and appliances.
- Participate in your local utility's energy conservation programs.
