Air Pollution from Asia- Hazard to World!

As per the study by Yuan Wang, a former doctoral student at Texas A&M, along with Texas A&M atmospheric sciences professors Renyi Zhang and R. Saravanan and NASA's Jet Propulsion Laboratory researchers’ , excessive Air pollution in Asia is having worse effects on world's weather and climate patterns.

With the help of  climate models and data collected about aerosols and meteorology over the past 3 decades, the researchers found that air pollution over Asia ,mostly from China , is impacting global air circulations, especially the upper atmosphere and it appears to make such storms or cyclones even stronger. According to Zhang, this effects the cloud formations, precipitation, storm intensity and other factors and ultimately impacts climate. Mostly, pollution from Asia is having significant consequences on the weather pattern over North America.

Due to thriving economy in China during the past 3 decaded ,there has been  building of enormous manufacturing factories, industrial plants, power plants and other facilities that generate huge amounts of air pollutants. Once emitted into the atmosphere, pollutant particles affect cloud formations and weather systems worldwide. Further, Increase in coal burning and car emissions have been major sources of pollution in China and other Asian countries.

Air pollution levels in some Chinese cities, such as Beijing, are often more than 100 times higher than acceptable limits set by the World Health Organization standards.

As the result,lung cancer rates have increased 400 percent in some areas due to excessive air pollution problem. It may be seen that conditions may worsen during winter months when a combination of dull weather patterns mixed with increased coal burning in many Asian cities can create pollution and smog that can last for weeks.

Enormous amounts of aerosols from Asia go upto six miles up in the atmosphere and these have an obvious impact on cloud formations and weather. Some future research on exactly how these aerosols are transported globally and impact climate will be assumed by researchers. Yuan Wang, who conducted the research with Zhang while at Texas A&M, currently works at NASA's Jet Propulsion Laboratory as a Caltech Postdoctoral Scholar.
