Abstract:

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
