RESEARCH DIRECTED TOWARD THE STUDY OP THE RELATION OP SOLAR ENERGY VARIATIONS TO CHANGES OP THE TROPOSPHERIC CIRCULATIONS

摘要

This report summarizes various applications of spectrum analysis and Chree analysis to solar-weather relations.n It is shown that at times of 27-day recurrent magnetic storms, the spectrum of the zonal index tends to have an unusually sharp peak near 27 days. This peak is characteristic of total hemispheric indices, in the eastern half of the hemisphere, but not of the western half.
