PLANETARY TIDE FORCE TRIGGERING SOLAR FLARES

In this paper, solar tide dynamics is briefly reviewed and it is pointed out that the effect of plantary tide force on triggering solar flares is more obvious for flares with stronger intensity, and that the ratio of outputs of strong planetary tide force triggering flares with Imp≥ 3 to weak ones is as high as 9.33. This fact revealed in this paper is significant in prediction of disturbances in solar-terrestrial space.
