EFFECT OF CURRENTS IN SOLAR ACTIVE REGIONS

On the basis of several important observational facts which relate closely to the currents in AR5395, it is considered that the direct key factor causing flare eruption is the enhancement of currents in the active region. In light of this idea, the energy storing process of flare phenomena is analysed and the motion equation as well as the energy equation is established. According to the observational data of AR5395, the theoretical computation and discussion are performed on the possibility of the occurrence of flares caused by current enhancement in the active region. By and large, the results coincide with the observational results.
