摘要:
The function α that describes the generation of large scale magnetic fields from small scale motions is assumed to be non‐zero only in a thin boundary layer. As a consequence, the problems for the poloidal and meridional fields in a symmetric rotating configuration decouple and may be solved sequentially. Analysis of the boundary layer yields equivalent boundary conditions on interior and exterior field components. The general eigenvalue problem is formulated but only the case of neutral stability is examin
