The Current Convective Instability and its Application to Diffuse Auroral Scintillation Causing Irregularities

Abstract

A stable E X B gradient drift geometry can become destabilized by a current along the magnetic field. This type of instability is generically called the current convective instability. This instability may be responsible for the diffuse auroral scintillation causing F region irregularities observed by the DNA Wideband satellite. In these phenomena the northward TEC gradient dominated the altitude electron density gradient. We have investigated a simple plasma fluid model and found that instability results for certain cases.
