Abstract. Aerosols affect the climate system by changing cloud characteristics in many ways. They act as cloud condensation and ice nuclei, they may inhibit freezing and they could have an influence on the hydrological cycle. While the cloud albedo enhancement (Twomey effect) of warm clouds received most attention so far and traditionally is the only indirect aerosol forcing considered in transient climate simulations, here we discuss the multitude of effects. Different approaches how the climatic implications of these aerosol effects can be estimated globally as well as improvements that are needed in global climate models in order to better represent indirect aerosol effects are discussed in this paper.

Simulation of direct radiative forcing of aerosols and their effects on East Asian climate using an interactive AGCM-aerosol coupled system (2012, background): “Secondly, aerosol particles acting as cloud condensation or ice nuclei can change cloud microphysical and radiative properties and cloud lifetimes, and hence indirectly affect the climate (Twomey 1977; Albrecht 1989; Ramaswamy et al. 2001; Lohmann and Feichter 2005; IPCC 2007).”
Point-source inertial particle dispersion (2009, neutral): “For example, we mention the implications on: climate dynamics and hydrological cycles (Lohmann and Feichter 2005 , IPCC 2007 ), mainly in connection to global climate changes originated by PM-induced cloud formation (Celani et al.”
Ice nucleation activity of bacteria isolated from cloud water (2013, background): “In the atmosphere as aerosols, such bacteria could play important roles by nucleating ice in supercooled clouds, which generally results in precipitation at mid-latitudes (Lohmann and Feitcher, 2005).”
Constraining cloud droplet number concentration in GCMs suppresses the aerosol indirect effect (2009, background): “Possibly, the precipitation efficiency is simultanously decreased (indirect cloud lifetime effect) [ Lohmann and Feichter, 2005 ].”
Long-term features of cloud microbiology at the puy de Dôme (France) (2012, background): “Since the formation of ice crystals in clouds generally enhances the chances of precipitation (Lohmann and Feitcher, 2005), the implication of ice nucleation active (INA) bacteria in precipitation processes has been proposed (Vali et al.”
