A conference was held at the Air Force Cambridge Research Laboratories on June 1, 1964 to discuss solar radio data and ionospheric effects of the total solar eclipse of July 20, 1963. A total of fifteen papers and summations of experiments performed and observations made during the eclipse were discussed at this workshop conference. This written proceedings of the conference is divided into three parts beginning with a part on solar radio flux measurements, continuing with a part on direct, quantitative measurements of ionospheric parameters, and concluding with one on indirect effects of ionospheric changes.
A general description of AFCRL's new 29-ft parabolic antenna is given. This antenna, designed for operation at 35 Gc, has Cassegrain feed optics and a precise reflecting surfdce supported on an elevation over azimuth mount. Design parameters include a gain of 67.5 dB at 35 Gc and a pointing capability of better than =1 arc min under 30-knot wind loads, normal solar loading, and peak accelerations of .012 deg/sq sec. The servo system was designed primarily to track objects traveling at sidereal rates. A limited satellite tracking capability should exist, however. Emphasis is given to engineering aspects of the tower, mount, drive system, and reflector assembly which should provide efficient rf operation and extreme precision in pointing. (Author).
This monograph is a case study of an outbreak of severe local storms that produced several tornadoes and extensive large hail in Oklahoma on 26 May 1963. Several authors have combined to describe the organization, structure, and evolution of these storms from a number of points of view. The storms are analyzed on four different size scales: (1) as products of their large-scale environment, (2) as members of a mesoscale system or family unit, (3) as individual evolving cells, and (4) as tornado and hail factories, with the emphasis on the tornadoes and the hailstones themselves. Data are obtained from conventional synoptic and mesosynoptic networks, visual and photographic observations, surface weather surveys, weather radars, sferics detectors, balloon tracks, radioactivity measurements in precipitation, and hailstone thin sections. Simple models are presented describing the airflow, structure and life cycle of individual severe local storms. (Author)
