Abstract
Aerosols affect Cloud properties, with possible significant impacts on climate. The relationship between increased areosols and smaller, more numerous cloud drops is well observed. More uncertainty remains due to uncertainties in ice nucleation. These changes in microphysics may affect cloud radiative properties, cloud lifetime and precipitation. East Asia in particular has recently seen large changes in aerosols, and these might impact regional climate through changes in radiation and precipitation. These effects are examined using the National Center for Atmospheric Research (NCAR) Community Earth System Model (CESM). The global atmospheric model features a new 2-moment microphysics scheme and is linked to a new modal aerosol model using droplet and crystal activation. Basic climatologies and results of sensitivity tests using the model are presented with and without aerosol emissions from East Asia, indicating possible significant global and regional effects of anthropogenic aerosols on clouds, precipitation and cloud feedbacks in the 21st century due to anthropogenic greenhouse gases and aerosols. |
