GEM: Magnetosheath Model Validation

研究人员将利用磁流体动力学(MHD)模型和ISTP卫星的数据研究磁鞘的大尺度结构。研究领域包括MHD模拟预测的磁层‘sash’的发生，磁层顶中的耗尽层，以及磁鞘中的冲击所产生的扰动。在磁层顶发生的过程产生特征信号，这些特征信号可以从远离磁层顶的磁鞘内的位置远程观察到。通过识别这些磁鞘特征，研究人员将获得有关磁层顶现象发生模式的有用信息。该奖项将支持与伊斯坦布尔技术大学一名教授的合作努力。研究成果将支持国家空间天气计划和地球空间环境建模计划的目标。

The investigators will study the large-scale structure of the magnetosheath using magnetohydrodynamic (MHD) models and data from the ISTP satellites. Areas of study include the occurrence of the magnetospheric 'sash' predicted by MHD simulations, the depletion layer in the magnetopause, and disturbances produced by shocks in the magnetosheath. Processes occurring at the magnetopause generate characteristic signatures that can be observed remotely from positions within the magnetosheath considerably removed from the magnetopause. By identifying these magnetosheath signatures, the investigators will gain useful information concerning the occurrence patterns of magnetopause phenomena. The award will support collaborative efforts with a professor at Istanbul Technical University. The research results will support the goals of the National Space Weather Program and the Geospace Environment Modeling Program.
