Zusammenfassung |
Non-linear α-ω; dynamo
waves existing in an incompressible medium with the turbulence dissipative
coefficients depending on temperature are studied in this paper. We investigate
of α-ω solar non-linear dynamo waves when only the first
harmonics of magnetic induction components are included. If we ignore the second
harmonics in the non-linear equation, the turbulent magnetic diffusion
coefficient increases together with the temperature, the coefficient of
turbulent viscosity decreases, and for an interval of time the value of dynamo
number is greater than 1. In these conditions a stationary solution of the
non-linear equation for the dynamo wave's amplitude exists; meaning that the
magnetic field is sufficiently excited. The amplitude of the dynamo waves
oscillates and becomes stationary. Using these results we can explain the
existence of Maunder's minimum. |
