Аннотация: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 reexamined. 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.
