Outline of Final Research Achievements

We aim to decide parameters for prediction of solar explosive and eruptive events based on understanding of physical processes. We performed observational verification of theoretical models and statistical data analysis for solar flares observed by the Hinode and SDO satellites. We quantitatively confirmed the physical processes and occurrence conditions of solar flare. Moreover, we proposed new candidates of parameters that would be useful for flare prediction, and discussed universality of our flare trigger model and its parameters.
