An Idealized Problem with F2-Layer Applications

摘要

An idealized problem is solved which illustrates the coupling between neutral air motion and the transport of plasma in a model F2 layer. The magnetic field lines are assumed to be horizontal and the effects of both vertically upwards and vertically downwards Hall drifts are considered. Very slow circulating motion of the neutral air is assumed to take place in a vertical plane parallel to the magnetic field lines. This motion is assumed to be coupled with the diffusive and Hall motions of the plasma. It is shown that if only the production and loss functions for electrons are known a non-linear diffusion equation is produced. (Author)
