旋转球壳中热对流产生两种类型的磁偶极子场。轴向（或赤道）偶极子，其中磁偶极矩平行（或垂直）的旋转轴是实现在一个较大（或较小）的瑞利数的值。它们的结构是鲁棒的，并持续在整个模拟期间，即，八（或两个）磁扩散时间。
Two types of magnetic dipole fields are generated by thermal convection in a rotating spherical shell. The axial (or equatorial) dipole in which the magnetic dipole moment is parallel (or perpendicular) to the rotation axis is realized at a larger (or smaller) value of the Rayleigh number. Their structure is robust and persists over the entire simulation period, that is, eight (or two) magnetic diffusion times.
