The goal of this proposal is to develop a model of turbulent fluctuations and transport in the magnetopause current layer. It continues work on the microphysics of the magnetopause by applying the investigator's model for the current convective instability to the magnetopause and to use the results to explore some of the macroscopic consequences. In particular, a fundamental goal is to obtain anomalous transport coefficients for the current diffusion which can then be incorporated in global MHD codes. The theoretical work proposed here is fundamental to developing an understanding of magnetic reconnection and anomalous transport at the magnetopause, which are thought to be key mechanisms for the transport of solar wind plasma into the magnetosphere.

这项建议的目标是发展一个模型的湍流波动和运输的磁层顶电流层。 它继续研究磁层顶的微观物理学，将研究人员的当前对流不稳定性模型应用于磁层顶，并利用其结果探索某些宏观后果。 特别是，一个基本的目标是获得异常的电流扩散，然后可以被纳入全球MHD代码的传输系数。 这里提出的理论工作是根本的磁层顶，这被认为是太阳风等离子体传输到磁层的关键机制的磁重联和异常传输的理解。
