Effects of Finite Current Channel Width on the Current Convective Instability.
Abstract
The effects of the finite current channel width on the current convective instability are studied both analytically and numerically. First, using a sharp-boundary field-aligned current distribution which has a finite width along the plasma density gradient, the dispersion relation is obtained analytically. Numerical results are also presented for a diffuse-boundary current velocity distribution. Applications to the high latitude ionosphere are discussed. Key words include: Plasma instability, High latitude ionosphere, Fluid instability, Finite current channel width.
