报告摘要：I present the results of comprehensive laboratory experiments and numerical studies addressing droplet growth and droplet size distributions in systems where droplets grow due to sustained supersaturation of their environment.

Both, for droplets condensing on a substrate (like dew) and droplets entrained in an external flow (like in clouds), we observe remarkable shortcomings of classical scaling theories addressing these growth processes. The origins of the discrepancies are identified, and appropriate extensions of the theories are discussed.

The issues about droplet distributions in the atmosphere might have some relevance to climate studies on earth. However, they are potentially much more useful for the description of atmospheres of brown stars and exo-planets.
