Book Description
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).

Book Description
The several components necessary to conduct experimental observations of the coalescence of cloud droplets under the influence of an introduced vortex were developed. These components include a laboratory cloud box (vertical lowspeed tunnel), a vortex-generating mechanism consisting of an airfoil and a propulsion device, and a telemicro camera capable of 5x magnification of objects 8 in. from the camera objective. Analysis of the effects of a model vortex upon a population of drops was done by means of electronic analog techniques, and these support the hypothesis that a single vortex tends to cause drops to become concentrated in a concentric band. The likelihood of collisions is thus increased. Radar studies of chaff drops in Project Hi-Cue, 1959, show that in one isolated case, a circulation did occur. Further experiments along these lines are recommended. Data collected at Flagstaff under Project Hi-Cue, 1961, are currently under analysis. The data logs for the raindrop-size spectrometer, the two-theodolite pibals, and the APQ-40 radar are included. In addition the results of basic computations on the raindrop-size and the pibals are reported. (Author).
