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

Comments
The further calculation shows that the dissipation is strong enough to suppress the helical-wave dynamo
