| Abstract: | We study a time – latitudinal distribution of CMEs observed by the SOHO spacecraft, their projected speeds and associated
magnetic fields, as well as the north – south (N – S) asymmetry of solar surface magnetic fields, and the coronal green line
intensities. We have found that (a) there exists an intricate relation between the average projected velocity of CMEs and
the mean value of large-scale magnetic fields; (b) there exists a pronounced N – S asymmetry in both the distribution and
the number of CMEs; (c) this asymmetry is in favor of the northern hemisphere at the beginning of the cycle, and of the southern
hemisphere from 2001 onward, being, in fact, (d) closely related with the N – S asymmetry in the distribution of large-scale
magnetic fields and the coronal green line intensities. |
