PY - 2012 DA - 2012/12/18 TI - Solar Field Mapping and Dynamo Behavior SP - 923578 VL - 2012 AB - We discuss the large-scale magnetic Field to the Sun- planetary environment.我们讨论了太阳大尺度磁场对太阳-行星环境的重要性。本文将研究的焦点集中在光球大尺度磁场的运动和演化上，光球大尺度磁场影响着整个区域的许多环境。为此，我们使用了一个新开发的Netlogo元胞自动机模型。这个算法模型的领域是太阳的光球层。在这个计算空间中放置了两种类型的实体或代理;人们可以把它们称为蓝知更鸟和红雀;前者具有向外的磁通，后者具有向内的磁通。人们可以简单地称它们为蓝剂和红剂。代理提供了平滑MHD模型中不存在的离散变化粒度;它们经历三个过程:在光球域内的诞生、运动和死亡。 We discuss these processes, as well as how we are able to develop a model that restricts its domain to the photosphere and allows the deeper layers to be considered only through boundary conditions. We show the model’s ability to mimic a number of photospheric magnetic phenomena: the solar cycle (11-year) oscillations, the Waldmeier effect, unipolar magnetic regions (e.g. sectors and coronal holes), Maunder minima, and the march/rush to the poles involving the geometry of magnetic field reversals. We also discuss why the Sun sometimes appears as a magnetic monopole, which of course requires no alteration of Maxwell’s equations.
