摘要: In this paper we discuss the sign of helicity in $\alpha$-$\Omega$ dynamo and propose a wave-$\Omega$ model which $\alpha$ effect geodynamo is induced by helical wave but not flow as solar dynamo. We then tentatively interpret mechanisms Earth's magnetic westward drift, tilt angle, dipole reversals.
