• A nonlinear analysis of the dynamic behavior of dissipative drift-waves isdeveloped. Near the neutral stable point, the time-dependent Ginzburg-Landauequation with complex coefficients is derived from the two-fluid equations whichdescribe the dissipative drift-waves, by means of reductive perturbation. Theconvective cell excited by the nonlinear self-interaction of a linearly stable drift-wave is undamped and is adiabatically enslaved by the drift-wave. The systemcomposed of the drift-wave and convective cell self-organizes as the externalmagnetic field exceeds a certain critical value and tends asymptotically to astable nonequilibrium state (nonlinear saturation). The saturation level of asingle, linearly unstable drift-wave in a non-isothermal plasma is obtained as afunction of critical wavenumber, density gradient scale length, plasma tempera-lure and magnetic field.
