A synthetic explanation on solar, interplanetary, and terrestrial phenomena by means of the two-hemisphere model

Three our papers on the heliomagnetosphere that were published within these four months are reviewed. Antipodal relation found in both solar M-regions and coronal hole tongues substantiates our two-hemisphere model on the three-dimensional structure of the heliomagnetosphere. Characteristics on reversals and excursions of the heliomagnetic dipole are discussed on the basis of an analysis of the K-corona, dark filament, and photospheric magnetic field. An application of the two-hemisphere model to the 27-day recurrence time patterns of the sector polarity and B sub(Z)-component of IMF, diurnal amplitude of cosmic ray intensity, geomagnetic C9 index, and geomagnetic Pc3 pulsation index enables us to explain synthetically the relations among these interplanetary and terrestrial phenomena.
