Abstract The MHD stability of tangential discontinuities is first considered. We treat these discontinuities as structured forms rather than as sharp breaks in the magnetic field. An unfamiliar form of the MHD energy principle is applied, and stability is proved provided that there is no fluid flow tangent to the ‘discontinuity’ plane. Perturbations which simply transform the system from one equilibrium to another are neutrally stable. Using comparison theorems we conclude that the observed stability of tangential forms in the solar wind implies near isotropy of the particle pressure in them.
