Abstract
Effects of the toroidicity and finite pressure on low-m ideal and resistive modes are studied numerically on the basis of the reduced set of the MHD equations. Both the linear and nonlinear analyses show that the m=2 mode is strongly destabilized by the above effects. The destabilization of the m=2 mode, however, is not directly related to the major disruptions. It is conjectured that the destabilized m=2 mode may change the equilibrium to the one unstable against the major disruption.Keywords
