摘要

The relationship between coronal mass ejections (CMEs) and corresponding X-ray flares was studied for the time interval covering cycle 23 and the beginning of cycle 24 (1996-2013). It is shown that the energy difference between CMEs and associated flares is larger at the decline of the solar cycle than in its rise phase. A similar relation is observed between the CME velocity (energy) and the effective solar multipole index, which characterizes the typical size of elements of the system of large-scale solar magnetic fields. This suggests that CMEs are mostly associated with individual active regions at the minimum and rise of the 11-year cycle, while the CME energy is mostly determined by active region complexes at the maximum and in the declining phase.
