Abstract

A method of measuring drop size distribution in clouds, especially adapted for wind tunnels and other cloud chambers in which the cloud is carried in an air stream, is presented. It consists of photographing the cloud illuminated both by a continuous source and a stroboscopic light. The fall velocities of the drops determined from the photographs are used with tables of terminal velocities to give the size distributions. The advantages of the method are discussed.
