Title: Ideal magnetohydrodynamic theory for localized interchange modes in toroidal anisotropic plasmas

Ideal magnetohydrodynamic theory for localized interchange modes is developed for toroidal plasmas with anisotropic pressure. The work extends the existing theories of Johnson and Hastie [Phys. Fluids 31, 1609 (1988)], etc., to the low n mode case, where n is the toroidal mode number. Also, the plasma compressibility is included, so that the coupling of the parallel motion to perpendicular one, i.e., the so-called apparent mass effect, is investigated in the anisotropic pressure case. Lastly, the singular layer equation is obtained, and the generalized Mercier's criterion is derived.
