摘要
A system of equations describing the two-dimensional nonlinear evolution of the two-stream and gradient-drift instabilities in the E-region of the Earth's ionosphere is derived, taking into account turbulent ion viscosity and the nonlinearity associated with the ion inertia. The linear instabilities are briefly re-examined. Regular nonlinear wave forms are found for both instabilities in the one-dimensional limit. Estimates of characteristic values of amplitudes and wavelengths are also presented.
