What is the Asian brown cloud made of?

All the Asian brown clouds consist of emissions from burning fossil fuels such as coal or petroleum or natural gas products and biomass ( wood, crop stubble). This so-called “Asian Brown Cloud” is also known as the ” Indian Ocean Brown Cloud.” which is an extensive layer of toxic air pollution.

How does the Asian Brown Cloud affect Asia?

The brown cloud also weakens winds during the Asian summer monsoon and changes the timing and location of monsoon rainfall. The cloud has dramatically thickened in recent decades, with some studies showing that dark aerosol emissions from China alone doubled between 2000 and 2006.

What are the brown clouds in space?

The brown cloud is a persistent, but moving, air mass characterized by a mixed-particle haze, typically brown in color. It also contains other pollution, such as ozone. “The scientists found that both brown cloud pollution and natural processes could contribute to unhealthy levels of ozone in the lower atmosphere.

What pollutants are emitted in the air from aging cars and factories?

Noxious gases, which include carbon dioxide, carbon monoxide, nitrogen oxides (NOx), and sulfur oxides (SOx), are components of motor vehicle emissions and byproducts of industrial processes.

What are the three factors that determine the level of air pollution?

Outdoor air quality, air-infiltration rates, and sources of emission of indoor pollutants are the major factors.

What does the mushroom cloud contain?

A mushroom cloud is a distinctive mushroom-shaped flammagenitus cloud of debris, smoke and usually condensed water vapor resulting from a large explosion. The effect is most commonly associated with a nuclear explosion, but any sufficiently energetic detonation or deflagration will produce the same effect.

What is the term brown air used for?

Solution(By Examveda Team) Photochemical smog which is mainly composed of ozone (O3), Peroxyacetyl nitrate (PAN) and Nox, is also known as brown air where solar radiation is intense.

Why is air quality in Denver so bad?

Denver’s air quality remains adversely impacted by the growth of ground-level ozone. When air pollution – car emissions, factory pollution, wildfire smoke, etc. – chemically reacts to direct sunlight, ground-level ozone results. Ground-level ozone damages air quality by infusing it with pollutants.
