Studies on individual cosmic ray storms in different components of the cosmic radiation were carried out for the Norwegian stations at Tromso and Bergen and for stations in Germany, Japan, and Tasmania. For each component individual cases were investigated regarding increasing phase displacement, with increasing storm time, between the amplitudes of the magnetic and cosmic ray storms. Further, the amplitudes of individual cosmic ray storms were measured for the neutrons, the soft component, the total radiation and for different hard components. In this way, information was obtained regarding the dependence of the amplitude of a cosmic ray storm on the mean energy of the primaries that produced the cosmic ray component in question. Also the dependence of cosmic ray storms on the geomagnetic latitude was investigated for different radiation components. The diurnal variation of cosmic ray storms was studied in a series of cases for different components and for mesons incident from different directions. Special cases of increases of the cosmic ray intensity and their dependence on the geomagnetic latitude were reported for a period of intense solar flare activity, September 18 to 23, 1957. Different possibilities for a theoretical description of the cosmic ray storm phenom ena and their connection with solar activity and magnetic storms were discussed. (auth)
