摘要:

The numerical evaluation of Taylor integrals in their natural geometry of a cylinder has long been a problem when considering the dynamics of the Earth's dynamo, as the Earth's natural coordinate system is a sphere. We describe an exact new method of dealing with the Taylor integrals while remaining in a spherical geometry. The procedure explained in this paper is valid for a full sphere and only the axisymmetric case is considered here.
