Low-frequency current instabilities in nonisothermal magnetoactive plasma

Radiophysics and Quantum Electronics Aims and scope

Abstract

The excitation of current instabilities in the lower ionosphere is studied for magnetic-field-aligned inhomogeneities of arbitrary length with allowance for electron-temperature perturbations and the dependence of electron collision frequency on electron temperature. It is found that the threshold velocity of Farley-Buneman instability has a minimum for a finite degree of inhomogeneity elongation when the temperature dependence of the electron collision frequency is sufficiently strong.
