Photospheric Magnetoconvection

该项目将使用磁图和滤波图序列来得出磁通量浓度的流程图和位移时间历史。此外，PIS将研究几个超颗粒及以下尺度上的通量在太阳表面上的扩散，特别是流动对场存在的反应。中心目标是找到一个合适的模型来描述与光球磁通量相关的传输现象。具体地说，PI希望了解扩散系数的差异、与经典随机游走的偏差以及流型与局部平均磁通密度的关系。该项目将结合高分辨率数据，以利用大视场的不间断长持续时间序列详细研究亚弧秒级拓扑和通量动力学，从而能够对通量位移历史进行统计研究。该计划将提供一种系统和连贯的分析手段，特别侧重于磁对流。

This project will use magnetogram and filtergram sequences to derive flow maps and time histories of displacements of concentrations of magnetic flux. In addition, the PIs will study the dispersal of flux over the solar surface on scales of several supergranules and below, particularly the reaction of flows to the presence of fields. The central goal is finding an appropriate model to describe the transport phenomena associated with photospheric magnetic flux. Specifically, the PIs hope to gain understanding of the differences in the diffusion coefficients, to the deviations from classical random walk, and to the dependence of the flow pattern on the local mean magnetic flux density. The project will combine high-resolution data to allow a detailed study of subarcsecond topology and flux dynamics with uninterrupted long-duration sequences with large fields of view, allowing a statistical study of flux displacement histories. The program will provide a means for systematic and coherent analysis, specifically focusing on magnetoconvection.***
