Bidirectional tornado modes on the Joint European Torus
TL;DR: In this paper, a suite of equilibrium and spectral magnetohydrodynamical codes are used for explaining the observed evolution of the tornado mode frequency and for determining the temporal evolution of safety factor inside the radius just before sawtooth crashes.

Resistive instabilities in general toroidal plasma configurations
TL;DR: In this article, the Mercier criterion for the stability of the ideal magnetohydrodynamic interchange mode is derived, the generalization of the earlier stability criterion for resistive interchange mode was obtained, and a relation between the two was noted.

A theory of long‐period magnetic pulsations: 2. Impulse excitation of surface eigenmode
Liu Chen,Akira Hasegawa +1 more
TL;DR: In this paper, a wave equation that shows a coupling between a surface wave and a shear Alfven wave is derived, and a theory of long-period magnetic pulsations (Pc 3 to Pc 5) is presented as an initial value problem to explain impulse-excited pulsations.

Decay of MHD waves by phase mixing
J. Tataronis,W. Grossmann +1 more
TL;DR: In this article, the authors examined the dispersion relation for plasmas with non-uniform profiles and compared the results with those of a sharp boundary model, showing that the frequency of the waves is a complex quantity having a real and imaginary part.

Kinetic-ballooning-mode theory in general geometry
TL;DR: In this article, a systematic procedure for studying the influence of kinetic effects on the stability of MHD ballooning modes is presented, which includes effects due to finite gyroradius, trapped particles, and wave-particle resonances.
