Abstract : A literature review of materials pertaining to the coalescence of cloud droplets in forming rain and to the prominant factors that influence this process is presented. Laboratory work in evolving a method for producing individual vortices reproducibly is discussed, and an airfoil modeled for use in a cloud chamber is described. The development of a 24-cu ft-capacity continuous cloud chamber is described, and the results of tests and analyses of its performance are reported. Satisfactory means of monitoring the cloud-chamber contents throughout experiments without disturbing the chamber and the cloud equilibrium are under study. A program of measurements of rain under Project Hi Cue was conducted at Flagstaff, Arizona, during July and August, 1959, using the van-mounted APQ-40 radar unit. (Author)
