Asian or Asian brown cloud brown clouds are created by a variety of airborne particles and pollutants from combustion (woodfires for example, cars, and factories), the combustion of biomass. combustion and industrial processes with untreated perfect. Brown cloud has always been associated with the winter monsoon (November / December to April) and appear as long as no rain is wet to wash pollutants from the air.
In terms of Health: One of the main impact is on health. A 2002 study showed that nearly two million people die every year in India alone, of the natural conditions related to Brown Clouds.
In terms of weather in each Region: A second assessment study which was published in 2008. It highlighted regional problems concerning:
Global warming and dimming
The 2008 report also addresses the concerns of global warming and concluded that the brown cloud has a density of 20 to 80 percent of greenhouse gases in a few centuries ago. The report suggests that air pollution may have an effect as well as strengthen and enlarge the global warming.Another major impact was on the ice at the poles. Black carbon layer in the Asian Brown Cloud can reflect the sun and Earth could experience a dimming but can occur elsewhere warming by absorbing the incoming radiation and atmospheric warming there. Carbon black having an impact three times more effective than carbon dioxide / greenhouse gases and the most common result is the effect of the melting of polar ice and snow.Carbon black in snowy regions causes about three times the change in temperature as carbon dioxide in the atmosphere. On the snowy area even at concentrations below five parts of carbon black permiliar trigger melting of the ice / snow, and may be responsible as 94persen of warming the Arctic.As a result, the Arctic ice sheet shrunk to the sea all year round, with more ice melting in the months of spring and summer and a little glacier formed in the fall and winter. Arctic sea ice melts during the summer of 2010 to cover the third smallest area.The extent of Arctic ice continues to decline at least by 11% per decade, and very quickly, in other words. Mark Serreze claims that prediction until September 2030, or more, the Arctic ice might not be there at all. It will look like a blue ocean.
1. Inhibits photosynthesis in plants. Against plants growing in areas with high air pollution levels can be stunted and prone to disease, among others chlorosis, necrosis, and black spots. Particulate deposited on plant surfaces may impede the process of photosynthesis.
3. Enhance the greenhouse effect. The greenhouse effect is caused by the presence of CO2, CFCs, methane, ozone, and N2O in the troposphere which absorbs the sun's heat radiation reflected by the surface of the earth. As a result of heat trapped in the troposphere and rise to the phenomenon of global warming. Global warming itself will result in; Melting ice at the poles, regional and global climate change, changes the life cycle of flora and fauna.
4. Damage to the ozone layer. Ozone layer in the stratosphere (20-35 km altitude) is a natural protector of earth that serves to filter ultraviolet B radiation from the sun. The formation and decomposition of ozone molecules (O3) occurs naturally in the stratosphere. Emissions of CFCs reach the stratosphere is very stable and causes the rate of decomposition of ozone molecules faster than formation, thus forming the holes in the ozone layer. Damage to the ozone layer causing UV-B sun rays are not filtered and can mengakibatkankanker skin as well as diseases in plants.
- Replacing motor vehicle fuel with fuel that produces no carbon monoxide gas
- Processing or recycling of waste industrial smoke
- Afforestation and reforestation or replanting trees substitute
