The Forbush decrease was analyzed on the basis of data on 92 magnetic storms recorded with a shielded ionization chamber at Tbilisi in l953-1955. It was observed that the Forbush decrease occurred only during large storms with sudden commencement; also, an increase in cosmic-ray intensity was registered prior to the commencement of such storms. The change in the cutoff point of the hard component was determined to be about the same during minimum and maximum solar activity, indicating that the nature of interaction between corpuscular streams and the geomagnetic field does not change greatly during minimum solar activity. The results of the analysis show that the corpuscular streams which cause large magnetic storms with sudden commencement are magnetized, that they contain a magnetic cushion in their forward part, and that they carry extensive high-intensity frozen-in magnetic fields.
