Abstract Text:
The relationship between several parameters of the H-alpha line at or near maximum is studied. These parameters are line width, central intensity, and flare area. The data were obtained from the I. A. U. Quarterly Bulletin. The correlations between any two of the three characteristics are quite loose, with large amounts of scatter as shown in the appended figures.

Bioastronautical Meassurements of Ionizing Radiations in Space: Nuclear Emulsion Monitoring Report

Abstract Text:
Four instrumented balloons were launched from Bemidji, Minnesota to secure cosmic ray data at high elevations and to study the effects of the radiations on biological systems. Each of the flights carried small units of nuclear emulsion to provide standardization data for other electronic instrumentation and to serve as directional monitors for heavy primary radiation penetrating the brains of the animals. Measurements were made of star production frequencies, proton enders, and heavy primary thindown hits. As a measure of solar proton enhancement, counts were made of the frequency of proton track enders in the emulsion. The ender production was essentially constant on all four flights, in agreement with earlier measurements in Minnesota, indicating the absence of any flare phenomena. It is suggested that the ratio of proton enders to stars may prove a useful parameter for indicating exposure to solar protons at balloon elevations, and small doses of trapped particles in animals flown in space probes and satellites which approach or graze the lower Van Allen belt.

The Role of Advection in the Formation of Vortex Cloud Patterns

Abstract Text:
A case study of the spiral cloud patterns associated with an atmospheric vortex, as seen by the TIROS I meteorological satellite, shows that advection can be a dominant mechanism in the formation of these patterns. This advection is then interpreted in terms of the horizontal and vertical structure of the low pressure system with which the clouds are associated. A comparison of the vortex cloud patterns, at the time of the maximum development of the spiral clear area, with Bergeron's two common types of cold fronts indicates that these patterns should be attributed to upper-air advection relative to the surface front rather than to vertical motion along the front. The similarities displayed by the spiraling vortex cloud patterns seen by TIROS I would suggest that the features found in this detailed case study would also hold for other cases in which this particular cloud pattern exists. The spiraling vortex patterns can be associated with a low pressure area on the surface analysis, but no general statement can be made that the reverse is also true. This case study indicates that the TIROS pictures are particularly well suited for the study of horizontal advection and show promise of yielding quantitative information.

The Relationship Between Large-Scale Vertical Motion and Sky Cover

Abstract Text:
The characteristic features of the sky cover in the northern hemisphere and their relationship to large-scale vertical motion are discussed. Evidence is presented in support of the hypothesis that the principal characteristics of the sky cover--amount and average height of cloud tops--are primarily determined by the largescale vertical motion, with convection playing a secondary role. Some implications of this hypothesis for analysis and forecasting of cloudiness and for the use of satellite observations of clouds and radiation in studies of atmospheric dynamics are mentioned.
