The tables present the results of computations of the intensity and the degree of polarization of sky radiation and radiation scattered by a unit volume of air containing natural aerosols. The tabulated data are based upon new values of the scattering functions i sub 1 and i sub 2 and the scattering cross sections k, derived using the Mie theory with m = 1.5. In the case of primary scattering of radiation, the results are valid for a turbid atmosphere. The tables of the scattering coefficients and optical thickness, the absolute scattering functions, the intensities, and the degrees of polarization are computed for various wavelengths between 0.4 and 1.2 microns and for discrete scattering angles between 0 degrees and 180 degrees. Aerosol size distributions of the form dn(r) = c.r/v dlogr, with v = 2.5, 3.0, and 4.0, are assumed. The lower and upper limits for the size range were chosen as r sub 1 = 0.04, 0.06, and 0.08 micron and r sub 2 = 3, 5, and 10 microns respectively. (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)
