项目摘要

This is a fellowship project to carry out a statistical study, case studies, and simulations of electromagnetic energy transfer via ULF waves that will place important constraints on the amount of energy that can be transported via ULF waves globally and in different frequency bands. In situ estimates of the energy transfer will be made using electric and magnetic field measurements from the Time History of Events and Macroscale Interactions During Substorms (THEMIS) five satellite constellation. the results will be interpreted in terms of magnetospheric energy transfer modes using case studies and magnetohydrodynamic (MHD) simulations. The work will be conducted at the University of Michigan in the Atmospheric, Oceanic, and Space Sciences (AOSS) Department under the mentorship of Professor Mark Moldwin.The project will have broader impacts as it includes a commitment from the team to disseminate their research to a broad audience at local K-12 schools and outreach events as well as develop new outreach materials that communicate the importance of energy transfer via ULF waves. In addition, Some ULF wave modes can interact with radiation belt electrons, creating energetic particles that pose a threat to satellites. The study of energy transfer via ULF waves, therefore, may have important societal impacts in helping to improve space weather radiation belt modeling.

这是一个奖学金项目，旨在通过ULF波进行电磁能量传输的统计研究，案例研究和模拟，这将对全球和不同频段的ULF波传输的能量量产生重要限制。将利用亚暴期间事件和大尺度相互作用的时间历史（THEMIS）五个卫星星座的电场和磁场测量值对能量转移进行现场估计。这些结果将用实例研究和磁流体动力学（MHD）模拟来解释磁层能量传输模式。这项工作将在密歇根大学的大气，海洋，该项目将产生更广泛的影响，因为它包括团队的承诺，将他们的研究成果传播给当地的K-12所学校和外展活动，以及开发新的外展材料，通过ULF波传达能量转移的重要性。此外，一些ULF波模式可以与辐射带电子相互作用，产生对卫星构成威胁的高能粒子。因此，通过超低频波的能量转移的研究，可能会有重要的社会影响，帮助改善空间天气辐射带建模。
