论文摘要
在这篇综述中，我们解释了Sun的Babcock-Leighton Dynamo模型中最近取得的进展，这些模型最成功地解释了太阳周期的各种特性。通常，这些模型是2D轴对称，平均场功能方程在太阳的meriodional平面上求解。这些模型中涉及的各种物理过程（例如，磁性浮力和Babcock-Leighton机制）本质上是3D过程，无法在2D框架中正确建模。在指出了2D模型的局限性（例如，平均场Babcock-Leighton Dynamo模型和表面通量传输模型）之后，我们描述了最近开发的下一代3D Dynamo模型，这些模型实现了更复杂的磁通量算法的浮力磁管的更复杂的磁通算法，而不是先前的2D模型，并且捕获Babcock-Leighton Process在对流区域和捕获更现实的2D模型。提出了这些3D发电机模型的详细结果，包括表面通量传输对应物。我们通过仅在倾斜角度引入散射来解释在3D Dynamo模型中复制的循环不规则。还讨论了通过将观察到的光电对流速度场吸收到3D模型中的一些结果，并指出了这些3D模型所能提供的广泛机会。
In this review, we explain recent progress made in the Babcock-Leighton dynamo models for the Sun, which have been most successful to explain various properties of the solar cycle. In general, these models are 2D axisymmetric and the mean-field dynamo equations are solved in the meriodional plane of the Sun. Various physical processes (e.g., magnetic buoyancy and Babcock-Leighton mechanism) involved in these models are inherently 3D process and could not be modeled properly in a 2D framework. After pointing out limitations of 2D models (e.g., Mean-field Babcock-Leighton dynamo models and Surface Flux Transport models), we describe recently developed next-generation 3D dynamo models that implement more sophisticated flux emergence algorithm of buoyant flux tube rise through the convection zone and capture Babcock-Leighton process more realistically than previous 2D models. The detailed results from these 3D dynamo models including surface flux transport counterpart are presented. We explain the cycle irregularities that are reproduced in 3D dynamo models by introducing scattering around the tilt angle only. Some results by assimilating observed photospheric convective velocity fields into the 3D models are also discussed, pointing out the wide opportunity that these 3D models hold to deliver.
