Various dynamical processes observed in the atmosphere are related to phase transitions from the gas phase. In this presentation selected nucleation and condensation processes are considered and their relevance to atmospheric aerosols is discussed. A few recent experimental studies are reviewed. Open questions remain particularly in the field of phase transitions in binary and multicomponent systems. The influence of miscibility and solubility of the compounds considered has not yet been clarified sufficiently. Furthermore, despite of numerous studies reported during the last few decades, the question of sticking probabilities of condensing vapor molecules remains controversial.

The...
