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.

谢菲尔德大学的太阳物理学和空间等离子体研究中心（SP2 RC）力求了解发生在近太阳表面、从光球到日冕的太阳大气层、太阳风、磁层和日光层的关键等离子体过程的性质，特别关注这些明显不同的区域的各种磁耦合机制。太阳大气层中释放的大部分能量通量（波或喷流）进入行星际空间，并影响地球的弓形激波，为磁层提供能量，并对我们的日常生活产生影响。将通过使用数学和数值建模以及对现有最新最先进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向太阳风和磁层的传播，从而推动空间气象。特别注意在这个复杂的和非常动态的耦合太阳-地球系统的波和射流过程。 我们的数学方法涉及先进的分析工作和并行高性能计算（网格和CUDA技术）的实施，结果将通过制造和使用空间（Hinode，SDO，IRIS，THEMIS）和地面（瑞典太阳望远镜/CRISP和CHROMIS，Dunn太阳望远镜/ROSA和IBIS以及即将到来的丹尼尔K。Innouye Solar Telescope/VBI and VTF）观测。拟议的方案涉及六个科学项目：1）非均匀（非）理想等离子体中MHD波和不稳定性的高级建模; 2）太阳大气中的三维小尺度动力学; 3）从喷流到波并应用于太阳大气：局部脉冲MHD动力学的三维建模和分析; 4）未解决的无碰撞冲击问题; 5）辐射带中关键波发射的动力学; 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重要的访问研究员方案。 我们要求提供资金以支付RA的工资，主要研究者和七名合作研究者的研究领导/管理和研究时间的适当费用，为适度但必不可少的访问研究员计划提供资金，用于旅行和生活费，计算机设备和消耗品，以及为我们的科学官员和秘密支持职位的相关延续提供资金。
