Air Pollution from Asia Affecting World's Weather
Jan. 21, 2014 — 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.
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 of Nature 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." (...)
