英文摘要 | We investigate the equilibrium climate response to East and Southeast Asian emissions of carbonaceous aerosols and sulfur dioxide, a precursor of sulfate aerosol. Using the Community Earth System Model with the Community Atmosphere Model version 5.3, we find that anthropogenic aerosol emissions from East and Southeast Asia exert a global mean net radiative effect of -0.49 +/- 0.04 W/m(2). Approximately half of this cooling effect can be attributed to anthropogenic sulfur dioxide emissions. The aerosol emissions drive widespread cooling across the Northern Hemisphere. Strong suppression of precipitation occurs over East and Southeast Asia, indicating that anthropogenic aerosol emissions may impact water resources locally. However, in contrast to previous research, we find no clear evidence of remote effects on precipitation over Australia and West Africa. We recommend further investigation of possible remote effects. Plain Language Summary Aerosols-particles suspended in the atmosphere-influence clouds and the climate system. Using a state-of-the-art global climate model, we investigate the climate impacts of aerosol emissions from human activity in East and Southeast Asia. We find that these aerosol emissions lead to widespread cooling across the Northern Hemisphere and also to reduction of rainfall over East and Southeast Asia, potentially impacting water resources. |
