1. Aerosol-Cloud-Precipitation Interactions in the Climate System
In AR4 and earlier reports, focus was on aerosol direct radiative effects and cloud albedo effects
Aerosols act in numerous other ways, considered feedbacks in AR4 – This discussion will need to be enhanced
Cloud and precipitation dynamics
Monsoon dynamics
Hurricane dynamics
Teleconnections via SST: MOC, NAO, Amazon…
Aerosol-precipitation effects may have greater impact than temperature effects
Aerosols are considered as geoengineering tools – this will have to be discussed
Stratosphere
Benard cells
Treatment of aerosol-cloud-precipitation effects in models requires improvement
