Scientific paper

A geomagnetic tail current-sheet region, two-and-one-half-dimensional particle-mesh computer model is described which features: (1) the efficient solution of Ampere's equation by Fast Fourier techniques, (2) the incorporation of particle sources and sinks, (3) facilities for the simulation of finite width effects, and (4) the optional inclusion of a normal magnetic field component, linking through the sheet. Simulations based on the model show that current sheets with a non-zero normal field component and an infinite width are stable, with the particles tracing out Speiser-like orbits. Although finite-width sheets are unstable with respect to the ion tearing-mode instability, the presence of a normal magnetic field stabilizes the system. The results suggest that a geomagnetic substorm occurs when the normal magnetic field drops below the critical value needed for stability.
