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（SP2RC）致力于了解近太阳表面、太阳从光球层到日冕的大气层、太阳风、磁层和日光层中发生的关键等离子体过程的性质，特别关注这些明显不同区域的各种磁耦合机制。太阳大气中释放的能量通量（波或射流）的很大一部分进入行星际空间并影响地球的弓形激波，为磁层提供能量并影响我们的日常生活。将通过使用数学和数值模型以及对最新可用的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传播到驱动空间天气的太阳风和磁层。特别关注这个复杂且非常动态的日地耦合系统中的波和射流过程。 我们的数学方法涉及先进的分析工作和并行高性能计算（GRID 和 CUDA 支持技术）的实施，其中结果将通过制作和使用空间（Hinode、SDO、IRIS、THEMIS）和地面（瑞典太阳望远镜/CRISP 和 CHROMIS、邓恩太阳望远镜/ROSA 和 IBIS 以及即将推出的 Daniel K. Innouye 太阳望远镜/VBI 和 VTF）观测。拟议的计划涉及六个科学项目：1）MHD 波和非均匀（非）理想等离子体中不稳定性的高级建模； 2）太阳大气中的3D小尺度动力学； 3) 从射流到波浪及其在太阳大气中的应用：局部脉冲 MHD 动力学的 3D 建模和分析； 4）未解决的无碰撞冲击问题； 5）辐射带关键波发射动态； 6) 部分电离和电离非平衡太阳等离子体中的波。该计划还有一个充满活力和活力的访问研究人员计划。 我们请求资金用于支付 RA 的工资、首席研究员和七名联合研究员的研究领导/管理和研究时间的适当费用、为适度但重要的访问研究人员计划提供资金、用于旅行和生活、计算设备和消耗品，以及为我们的科学官员和秘书支持职位的相关延续提供资金。
