Scientific paper

A nonlinear two-dimensional model developed to examine the nonlinear state of two-stream plasma instability in the equatorial electrojet, uses two-fluid equations for electrons and ions in the vicinity of a northward magnetic field perpendicular to an applied electric field. Collisions with neutral species and a viscous representation of Landau damping of short wavelength modes are also included, while assuming the unperturbed plasma to be homogeneous and isothermal. Radar observations of isolated type 1 irregularities include horizontally directed waves, dominant and propagated at the speed of sound, and obliquely directed waves with lower spectral heights and propagated at speeds lower than the acoustic speed. Instability appears to saturate by a rotation of the electric field vector. This reduces the component perpendicular to the current density field vector to a lower value than the critical value for marginal safety, and appears to be a velocity reduction mechanism for reducing the instability to a marginally stable state.
