Detailed Assessment of Glaciated Clouds Aerosol Indirect Effects Using a Hybrid Bulk/Bin Microphysics Model
Results from the study showed that the contribution from glaciated clouds dominates the total aerosol indirect effect in both continental and maritime cases. This was predicted when only soluble aerosols were allowed to evolve from preindustrial to present-day aerosol loadings. This was principally because glaciated clouds are deeper and more extensive relative to water-only clouds. Secondly, because they exist above water clouds they therefore have the first interaction with solar radiation. The invigoration indirect effect is seen to have a cooling effect on the climate system. This is primarily due to an increase in cloud cover caused by the formation of secondary cells in the continental case while in the maritime case it has a warming effect. It was surprising to note that for the continental case, the glaciation effect was negative while the riming effect was positive.
