Application to STFC for Consolidated Grant Support for the Solar Physics and Space Plasma Research Centre (SP2RC) at The University of Sheffield

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、太阳风和磁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耦合机制。太阳大气中释放的能量流有很大一部分进入星际空间，冲击地球的弓形激波，为磁层提供能量，对人类的日常生活产生影响。将利用数学和数值模拟以及分析现有的最新卫星和地面数据集，研究太阳内部和近太阳次表层区域能量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问题。特别关注了这个复杂的、非常动态的日地物理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实施并行计算(GRID和支持CUDA的技术)，其中将通过进行和使用空间(SOHO、TRACE、HINODE、SDO、IRIS、CLUSTER、THEMIS)和地面(瑞典太阳望远镜、邓恩太阳望远镜)观测来测试和验证结果。拟议的方案涉及八个科学项目：1)原纤磁场对p模传播的影响；2)太阳大气中纽结波的能量传输和耗散；3)三维磁流体波正演模拟：局部化大气波导和喷流；4)ROSA/IBIS对较低太阳大气中MHD模及其绝对/相对能量通量的分类研究；5)高级太阳大气MHD波模型；6)用作全球日冕地震学手段的随机日冕全球波；7)1AU内无碰撞冲击的形成、结构和演化；8)对磁层内等离子波的新颖研究。该计划还有一个充满活力和活力的访问研究人员项目。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、首席调查员和八名协理调查员的研究时间、两个与特别项目有关的观察性博士生以培训该领域下一代专家的经费、一个规模不大但必不可少的访客研究员方案的经费、差旅和生活费、计算机设备和消耗品的经费。

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.
