Analysis and Prediction of Magnetospheric Plasma Energy Dynamics with the Wind Driven Magnetospheric-Ionospheric (WINDMI) Model

该合同将为各种太阳风驱动条件下磁层等离子体能量动力学模型的开发提供支持，特别关注地磁暴和亚暴。这项研究将对磁层-电离层系统对太阳风驱动条件的反应有重要的见解。新模型将为如何理解磁层中最大储层之间的总能量含量和能量转移提供有价值的信息。这些信息将用于在地磁事件发生之前和期间确定磁层的可能状态。新的模型将能够快速和可靠的预测，可以与更全面的磁流体动力学（MHD）或动力学模型的结果进行比较。该项目将为美国国家海洋和大气管理局（NOAA）的空间天气预报中心（SWPC）和美国国家航空航天局（NASA）运营的空间物理社区协调建模中心（CCMC）提供该模型的软件实现。空间天气及其影响在现代具有重要意义。对电气工程和系统工程专业的学生进行空间天气方面的培训，将提高技术人员的意识，并帮助他们更加了解空间天气的影响。在这个项目中要实现的科学方法和模型开发将被纳入其他高度理论化的工程师课程中。新模型在计算上运行起来很便宜。它可以很容易地移植到一个移动平台上，并被空间气象爱好者用来探索空间物理。本科生、12年级学生和公众将能够运行这个模型，并开始欣赏空间科学，同时对地球空间社区的工具和方法有一个强有力的了解。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award will provide support for the development of a model of the energy dynamics of plasma populations in the magnetosphere under various solar wind driving conditions, focusing in particular on geomagnetic storms and substorms. The research will achieve a significant insight into how the magnetosphere-ionosphere system responds to solar wind driving conditions. The new model would provide valuable information on how the total energy content and energy transfers among the largest reservoirs within the magnetosphere are to be understood. This information would be used to establish the possible state of the magnetosphere prior to and during geomagnetic events. The new model would be capable of fast and robust predictions that can be compared with results from more comprehensive magnetohydrodynamic (MHD) or kinetic models. The project would produce a software implementation of the model as a product to the Space Weather Prediction Center (SWPC) of the National Oceanic and Atmospheric Administration (NOAA) and the Space Physics Community Coordinated Modeling Center (CCMC) operated by NASA. Space Weather and its effects are assuming major importance in modern times. The training of students in Electrical Engineering and Systems Engineering in space weather will increase awareness among technologists and help them to become more aware of space weather effects. The scientific methods and model development to be achieved in this project will be incorporated into otherwise highly theoretical courses for engineers. The new model would be computationally inexpensive to run. It can be easily ported to a mobile platform and used by space weather enthusiasts to explore space physics. Undergraduate students, K¬12 students and the public, will be able to run this model and start to appreciate space science while getting a powerful glimpse into the tools and methods of the geospace community.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
