Climate Responses to Changes in European and Asian Anthropogenic Aerosol Since 1980
Abstract
There has been little change in global mean emissions of anthropogenic aerosol and their precursors since 1980, as decreases in European and North American emissions have been balanced by increases in Asia. Here we assess the similarity in the pattern and magnitude of the response to recent changes in European and Asian aerosol emissions in a hierarchy of models, and determine whether competition between the effects of increasing Asian and decreasing European emissions may have limited recent regional responses to aerosol. We pay particular attention to the hydroclimate response over global monsoon regions, European climate, and circulation precursors of poor air quality events in northeast China.
