Two-dimensional equilibrium of a neutral sheet in a gravitational field

We solve the two-dimensional MHD-equations to find the equilibrium structure of a neutral sheet having its axis parallel to the gravitational field in an atmosphere. The evolution of an initially plane sheet which is a self-consistent, non-equilibrium solution of the MHD-equations, is followed until static equilibrium of forces is obtained. The effect of field line anchoring in a cool dense layer at the bottom of the sheet is taken into account.Presently at The Auroral Observatory, Boks 953, 9001 Tromsø, Norway.
