Abstract: | Aircraft observations and model simulations show that cloud development is strongly modulated by the impact of cloud-aerosol
interactions on precipitation forming processes. New insights into the mechanisms by which aerosols dominate the cloud cover
of marine shallow clouds suggest that feedbacks between the cloud microstructure and cloud dynamics through precipitation
processes play a major role in determining when a solid cloud cover will break up into a field of trade wind cumulus. Cloud-aerosol
interactions dominate not only the dynamics of marine shallow clouds, but also the lifetime and the vertical disposition of
latent heat of deep convective clouds over ocean and even more strongly over land. Recent coincident satellite measurements
of aerosols and cloud properties quantify the aerosol effects on cloud cover and radiative forcing on regional and global
scales. The shapes of the satellite retrieved relations between aerosols and cloud properties are consistent with the suggested
ways by which aerosols affect clouds via precipitation processes, particularly by affecting the intensity of the cloud vertical
air motions and its vertical development. |
