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, magnetosphere and heliosphere with particular attention devoted to the various magnetic coupling mechanisms of these apparently distinct regions. A large part of the energy flux released in the solar atmosphere (either waves or jets) travels into interplanetary space and impacts on the Earth's bow shock, energising the magnetosphere and having impact on our daily human life. The generation of energetic events in the solar atmosphere and their propagation into the solar wind and magnetosphere driving Space Weather will be rigorously investigated by using mathematical and numerical modelling and the analysis of latest available state-of-the-art satellite and ground-based datasets. Particular attention is paid to the wave and jet processes in this complex and very dynamic coupled Sun-Earth system. Our mathematical approach involves advanced analytical work and the implementation of parallel high-performance computing (GRID and CUDA-enabled technology) where results will be tested and verified by making and using space (Hinode, SDO, IRIS, THEMIS) and ground-based (Swedish Solar Telescope/CRISP and CHROMIS, Dunn Solar Telescope/ROSA and IBIS and the upcoming Daniel K. Innouye Solar Telescope/VBI and VTF) observations. The proposed programme involves six scientific projects: 1) Advanced modelling of MHD waves and instabilities in non-uniform (non)-ideal plasmas; 2) 3D small-scale dynamics in the solar atmosphere; 3) From jets to waves with applications to the solar atmosphere: 3D modelling and analysis of localised impulsive MHD dynamics; 4) Unsolved problems of collisionless shocks ; 5) Dynamics of key wave emissions in the radiation belts; and 6) Waves in partially ionised and ionisation non-equilibrium solar plasmas. The programme also has a vibrant and vital Visiting Researchers Programme. We request funding to cover salaries of the RAs, appropriate costs for research leadership/management and research time for the Principal Investigator and seven Co-Investigators, funding for a modest but essential Visitor Researcher Programme, for travel & subsistence, computing equipment and consumables, and funding for the associated continuation of our Scientific Officer and Secreterial Support posts.

谢菲尔德大学太阳物理和空间等离子体研究中心试图了解发生在近太阳表面、太阳大气层从光球层到日冕、太阳风、磁层和日光层的关键等离子体过程的性质，并特别关注这些明显不同区域的各种磁耦合机制。太阳大气中释放的大部分能量流(波或喷流)进入星际空间，冲击地球的弓形激波，为磁层提供能量，并对人类的日常生活产生影响。将利用数学和数值模拟以及对现有最先进的卫星和地面数据集的分析，严格研究太阳大气中高能事件的产生及其传播到太阳风和磁层驱动空间天气的问题。特别关注了这个复杂的、非常动态的日地耦合系统中的波动和喷流过程。我们的数学方法涉及高级分析工作和实施并行高性能计算(GRID和支持CUDA的技术)，其中将通过进行和使用空间(Hinode、SDO、IRIS、THEMIS)和地面(瑞典太阳望远镜/CRISP和CRUMIS、Dunn太阳望远镜/ROSA和IBIS以及即将进行的Daniel K.Innouye太阳望远镜/VBI和VTF)观测来测试和核实结果。拟议的计划涉及六个科学项目：1)非均匀(非)-理想等离子体中MHD波和不稳定性的高级模拟；2)太阳大气中的3D小尺度动力学；3)从喷流到波的应用：局部脉冲MHD动力学的3D模拟和分析；4)未解决的无碰撞激波问题；5)辐射带中关键波发射的动力学；以及6)部分电离和电离非平衡太阳等离子体中的波。该方案还有一个充满活力和活力的访问研究人员方案。我们要求拨款以支付研究助理的薪金、研究领导/管理的适当费用、首席调查员及七名协理调查员的研究时间、一项规模不大但必需的访客研究员计划的经费、旅费及生活费、电脑设备及消耗品，以及有关延续我们的科学主任及机密支援职位的经费。
