Turbulent transport of magnetic fields. IV - Damping of the mean field (B) in alpha-squared dynamos with alpha proportional to COS Theta
Abstract
It is proven that the dynamo equation for the mean field (B) of the spherical alpha-squared dynamo with alpha proportional to cos Theta and constant beta have only exponentially damped solutions, if the mean energy density (B-squared) is nonzero and finite. The origin and interpretation of this phenomenon is reviewed.
