GEM: Turbulent Structure of the Magnetopause Current Layer

本研究的目的是建立磁层顶电流层湍流波动和输运的模型，该模型可以与无碰撞重联的模拟相结合，并与观测结果进行比较。磁层顶过程很重要，因为磁层顶是磁鞘中受冲击的太阳风等离子体和磁层等离子体之间的边界。磁层顶的磁重联和异常输运是太阳风等离子体向磁层输运的关键机制。这项工作是一项研究的延续，其中完成了不稳定性的静电极限的动力学处理，并进行了三维非线性流体模拟。在这项持续的研究中，将进行更多的模拟，并将推导出的电场和磁场波动谱与航天器观测结果进行比较。＊＊＊

9300988 Drake The goal of this research is to develop a model of turbulent flucutations and transport in the magnetopause current layer which can be coupled with simulations of collisionless reconnection and compared with observations. Magnetopause processes are important because the magnetopause is the boundary between the shocked solar wind plasma in the magnetosheath and magnetospheric plasma. Magnetic reconnection and anomalous transport at the magnetopause are key mechanisms for the transport of solar wind plasma into the magnetosphere. This effort is a continuation of a study in which a kinetic treatment of the electrostatic limit of the instability was completed and 3-D nonlinear fluid simulations were carried out. In this continuing study, more simulations will be performed and the deduced electric and magnetic field fluctuation spectra will be compared with spacecraft observations. ***
