The coupling of the ionosphere to the magnetosphere is a critical component to the understanding of the dynamics of energy flow in these regions. This project will address the coupling that results from the interaction of the polar wind with the field-aligned electric potential drops that produce the so-called "inverted V" signature in ion energy spectrograms. The coupling process takes place on all spatial scales down to the ion gyroradius and this program will address the interaction mechanisms at all these scales. The program will determine the relative importance of a variety of phenomena, including the mirror force, convection, conduction, diffusion, and wave-particle interactions. This work will build on the transport model developed by the PI under prior NSF support.

电离层与磁层的耦合是了解这些区域能量流动动态的关键组成部分。 该项目将解决极风与场对齐电位降相互作用产生的耦合问题，场对齐电位降在离子能谱图中产生所谓的“倒V”特征。 耦合过程发生在所有的空间尺度下的离子回旋半径，这个程序将解决在所有这些尺度的相互作用机制。 该计划将确定各种现象的相对重要性，包括镜像力，对流，传导，扩散和波粒相互作用。 这项工作将建立在运输模型的PI开发下先前NSF的支持。
