GEOPHYSICAL EFFECTS OF SOLAR CORPUSCULAR RADIATION
Magetic storms, auroras, and cosmic-ray variations are explained from a unified theoretical point of view. The sudden commencement of magnetic storms seems to be due to ionospheric currents initiated by solar corpuscular radistion. The main phase of storms is explained in terms of an extra terrestrial ring currert set up by the drifting motion of trapped solar particles. These trapped particles are also accelerated to high enough energies to cause aurora; the acceleration proceeds mainly by Fermi collisions with magnetohydrodynamic waves (which give rise to geomagnetic micropulsations). Decreases in cosmicray intensity, which accompany magnetic storms, are produced by a diffusive deceleration process in interplanetary space. (auth)
