- An increase of anthropogenic greenhouse gases and atmospheric aerosols due to human activity is the main forcing
responsible for a climate change over the globe. While effects of anthropogenic greenhouse gases have been studied
extensively, a role of atmospheric aerosols is highly uncertain so far. Therefore, it is important to understand how
aerosol forcing is associated with climate variability to assess their impacts on climate change. In this study, we
performed a number of simulations using a Community Climate System Model (CCSM) version 2.0.1 to identify a
role of sulfate aerosol forcing on East Asian climate. It is found that a regional aerosol forcing (i.e., sulfate aerosol)
could modify the rainfall variability over northeast Asia during spring and summer time. Based on a long term
period of simulation, in addition, we could find that sulfate aerosol forcing is associated with changes in the North
Pacific Ocean SST variability.
