Cloud physics is concerned with those processes which are responsible for the formation of clouds and the release of precipitation. This classic book gives a comprehensive and detailed account of experimental and theoretical research on the microphysical processes of nucleation, condensation, droplet growth, initiation and growth of snow crystals, and the mechanisms of precipitation release. As a textbook it is designed to give the student the necessary background to carry out independent work. As a reference book for the research worker, it provides an integrated account of the major developments in this field. Although written primarily for the atmospheric physicist, it contains much of interest for those in the fields of nucleation phenomena, crystal growth, and aerosol physics.
