Extreme air pollution in Asia is affecting the world’s weather and climate patterns, according to a study by Texas A&M University and NASA’s Jet Propulsion Laboratory researchers, Science Daily reports.
Yuan Wang, a former doctoral student at Texas A&M, along with Texas A&M atmospheric sciences professors Renyi Zhang and R. Saravanan, have had their findings published in the current issue ofNature Communications.
Using climate models and data collected about aerosols and meteorology over the past 30 years, the researchers found that air pollution over Asia — much of it coming from China — is impacting global air circulations.
“The models clearly show that pollution originating from Asia has an impact on the upper atmosphere and it appears to make such storms or cyclones even stronger,” Zhang explains.
“This pollution affects cloud formations, precipitation, storm intensity and other factors and eventually impacts climate. Most likely, pollution from Asia can have important consequences on the weather pattern here over North America.”
China’s booming economy during the last 30 years has led to the building of enormous manufacturing factories, industrial plants, power plants and other facilities that produce huge amounts of air pollutants. Once emitted into the atmosphere, pollutant particles affect cloud formations and weather systems worldwide, the study shows.
Increases in coal burning and car emissions are 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, Zhang says.
The study was funded by grants from NASA, Texas A&M’s Supercomputing facilities and the Ministry of Science and Technology of China.
