SOLAR MAGNETIC CLOUD PRODUCING COSMIC-RAY STORM, MAGNETIC STORM, AND TYPE IV SOLAR RADIO OUTBURST
At the Moscow Meeting in 1959, good correlation was reported between the cosmic-ray storms and the solar flares associated with Type IV radio outbursts. In order to confirm this result, the study was continued for the data during the period 1959-1980 and the following results were obtained. (1) Cosmic-ray storms are closely associated with the radio outbursts of Type IV (continuum). The result indicates that the eruption followed by the radio outburst of Type IV is the cause of cosmic-ray storm. (2) The size of cosmic-ray and magnetic storm was compared with the heiiographic longitude of the eruptions. Large magnetic storms occur after eruptions near the central meridian, while the size of cosmic-ray storm is independent of the heliographic longitude of the eruption. (3) From these results, a possible model of magnetized corpuscuiar cloud is presented which seems to be ejected from the sun with eruption followed by Type IV outburst. This model of magnetic cloud is a large total bulk with a core and appears to be able to consistently explain not only the facts above described but also the other earth storms. (auth)
