| Outline of Final Research Achievements |
By combining magnetohydrodynamic simulation and satellite observation data analysis, we conducted a research on the formation mechanism of sunspots and active regions and the occurrence of solar flares. As a result, we revealed for the first time that the vigorous explosions and jet ejections seen in the developing phase of the sunspots are caused by magnetic reconnection, which is driven by magneto-convective evolution. Also, we carried out statistical data analysis on the active regions that produced large-scale solar flares and found that, for example, the flare duration is correlated with the length of magnetic fields, larger active regions have less coronal mass ejections, etc.
