Abstract:

A complete review of published information on droplet formation and growth, droplet distribution in fog, and the cloud thermodynamic processes was completed. This investigation clearly indicated a great dearth of information available concerning droplet distributions for droplets where r is less than 3 microns. The radiative cooling investigation is reported. An analysis of factors in the growth of cloud or fog droplets was made which indicated that the droplet growth rate is a function of curvature, the latent heat which must be transferred from the surface of the droplet, surface tension, and salinity. This phase of the work clearly shows that for certain ranges of radius r, the growth rate drdt is much less dependent on the relative humidity than might have been thought. The development of a generating function by which fog droplet distributions can be approximated is reported.
