论文摘要
差异旋转的轮廓以及α效应的符号决定了发电机波方向。在太阳能发电机的早期模型中，发电机波通常会导致活动带的极点迁移。通过子午流或表面剪切层的影响是可能的解决方案。在包括电晕在内的模型中，我们表明可以通过改变电晕的特性来获得各种迁移。 Babcock-Leighton类型的一种新的发电机还导致了通过通量密度与通量上升时间之间的非线性关系的正确赤道迁移。
The profile of the differential rotation together with the sign of the alpha-effect determine the dynamo wave direction. In early models of the solar dynamo the dynamo wave often leads to a poleward migration of the activity belts. Flux transport by the meridional flow or the effect of the surface shear layer are possible solutions. In a model including the corona, we show that various migrations can be obtained by varying the properties of the corona. A new dynamo of Babcock-Leighton type also leads to the correct equatorward migration by the non-linear relation between flux density and rise time of the flux.
