An investigation of the requirements for the laboratory modeling of the motion of cloud droplets, using the principles of dynamic similarity and the concepts of induced mass and hydrostatic buoyancy. It is concluded that cloud droplets can be successfully modeled in the laboratory as long as the Reynolds number is small with respect to 18 and that the results can be compared with Hocking's theoretical results when the Reynolds number is less than one.
This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
