项目摘要

The Solar Physics and Space Plasma Research Centre (SP2RC) at the University of Sheffield seeks to understand the nature of key plasma processes occurring in the near-solar surface, the atmosphere of the Sun from photosphere to corona, solar wind and magnetosphere with particular attention devoted to the various coupling mechanisms of these apparently distinct regions. A large part of the energy flux released in the solar atmosphere travels into interplanetary space and impacts on the Earth's bow shock, energising the magnetosphere and having impact of our daily human life. The generation of energetic events in the solar interior and near solar sub-surface region and their propagation through the solar interior-atmosphere-space plasma system into solar wind and magnetosphere driving Space Weather will be investigated by using mathematical and numerical modelling and the analysis of latest available satellite and ground-based datasets. Particular attention is paid to the wave coupling processes in this complex and very dynamic physical Sun-Earth system. Our mathematical approach involves rigorous analytical work and the implementation of parallel computing (GRID and CUDA-enabled technology) where results will be tested and verified by making and using space (SOHO, TRACE, Hinode, SDO, IRIS, Cluster, THEMIS) and ground-based (Swedish Solar Telescope, Dunn Solar Telescope) observations. The proposed programme involves eight scientific projects: 1) The effect of fibril magnetic fields on the propagation of p-modes; 2) Kink wave energy transport and dissipation in the solar atmosphere; 3) 3D MHD wave forward modelling: Localised atmospheric waveguides and jets; 4) ROSA/IBIS classification study of MHD modes and their absolute/relative energy flux in the lower solar atmosphere ; 5) Advanced solar atmospheric MHD wave modelling; 6) Stochastic coronal global waves as means for global coronal seismology; 7) The formation, structure and evolution of collisionless shocks inside 1AU; and 8) Novel investigations of plasma waves in the inner magnetosphere. The programme also has a vibrant and vital Visiting Researchers project. We request funding to cover salaries of the RAs, appropriate costs for research leadership/management and research time for the Principal Investigator and eight Co-Investigators, funding for two special project-related observational PhD studentship in order to train the future generation of experts in the field, funding for a modest but essential Visitor Researcher Programme, for travel & subsistence, computing equipment and consumables.

谢菲尔德大学的太阳物理和空间等离子体研究中心（SP2RC）试图了解发生在近太阳表面的关键等离子体过程的本质，太阳大气从光球到日冕，太阳风和磁层，特别关注这些明显不同区域的各种耦合机制。太阳大气中释放的大部分能量流进入行星际空间，影响地球的弓形激波，激发磁层并影响我们的日常人类生活。利用数学和数值模拟以及对最新卫星和地面数据集的分析，研究太阳内部和近太阳亚表面区域高能事件的产生及其通过太阳内部-大气-空间等离子体系统传播到驱动空间天气的太阳风和磁层的过程。特别注意在这个复杂的和非常动态的物理太阳-地球系统中的波耦合过程。我们的数学方法包括严格的分析工作和并行计算（GRID和cuda支持技术）的实现，其中结果将通过制造和使用空间（SOHO， TRACE, Hinode， SDO， IRIS, Cluster， THEMIS）和地面（瑞典太阳望远镜，邓恩太阳望远镜）观测进行测试和验证。本项目涉及八个科学项目：1)原纤维磁场对p模传播的影响；2)扭结波能量在太阳大气中的输运和耗散；3)三维MHD波正演模拟：局域大气波导和射流；4)太阳低层大气MHD模态及其绝对/相对能量通量的ROSA/IBIS分类研究；5)先进太阳大气MHD波模拟；6)随机日冕全球波作为全球日冕地震学的手段；7) 1AU内无碰撞冲击的形成、结构和演化；8)内磁层等离子体波的新研究。该计划还有一个充满活力和重要的访问研究人员项目。我们要求资金用于支付研究员的工资、首席研究员和八名联合研究员的研究领导/管理和研究时间的适当费用、两名与特别项目相关的观察博士研究生的资金，以培养该领域的下一代专家、一个适度但必要的访问研究员计划的资金、旅费和生活费、计算设备和消耗品。
