China’s polluted air is changing the weather

Air pollution over Asia, most of which is coming from China, is affecting the world’s weather. The findings, published in the journal Nature Communications, are based on analysis of climate models and data collected about aerosols and meteorology over the past 30 years.  “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,” says Renyi Zhang, a professor of atmospheric sciences at Texas A&M University and a co-author of the study. “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.”
