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能物理和太空等离子体研究中心（SP2RC）试图了解在近极表面发生的关键等离子体过程的性质，从光电球到电动机，太阳能风能，磁层和地球层的太阳大气，特别注意这些明显不同的区域的各种磁性耦合机构。在太阳大气中释放的很大一部分能量通量（波浪或喷气机）进入星际空间，并影响地球的弓形冲击，使磁层充满活力，并影响了我们日常的人类生活。太阳大气中的能量事件的产生以及它们传播到太阳风和磁层驱动空间天气中的传播将通过使用数学和数值建模以及对最新可用的最先进卫星和地面数据集的分析进行严格研究。在这个复杂且非常动态的阳光地球系统中，特别注意波浪和喷射过程。 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望远镜/VBI和VTF）观测值。拟议的计划涉及六个科学项目：1）在非均匀（非）理想等离子体中的MHD波和不稳定性的高级建模； 2）太阳大气中的3D小规模动力学； 3）从喷射到波浪，并具有应用到太阳大气：3D建模和分析局部冲动MHD动力学； 4）无碰撞冲击的未解决问题； 5）辐射带中钥匙波排放的动力学；和6）部分电离和电离非平衡太阳等离子体中的波。该计划还具有充满活力且重要的访问研究人员计划。 我们要求资助资金来支付RAS的薪水，研究领导力/管理的适当费用以及首席研究员和七位共同投资者的研究时间，用于适度但必不可少的访客研究人员计划的资金，用于旅行和维生根，计算设备和消耗品，以及为我们的科学官员和秘密支持职位的相关延续的资金。
