这项资助是为了进行一项理论和观察研究, 磁层中的磁脉动 线性本征模 超低频(ULC)磁流体动力学分析。 波将 在现实的偶极场几何中执行。 特别 将关注非线性饱和机制 以及这种波如何影响粒子扩散。 这项研究的一个重要部分涉及使用观察到的环 当前离子分布(来自A M P T E C C E卫星) 作为下线性分析的输入, 超低频波的激发机制。 这些信息 沿着的非线性饱和机制的知识, ULF波可以提供对全球动力学的重要见解 环电流等离子体的。*//
英文摘要
This grant is for a theoretical and observational study of magnetic pulsation in the magnetosphere. A linear eigenmode analysis of ultra-low frequency (ULC) MHD. Waves will be performed in a realistic dipole field geometry. Special attention will be given to the nonlinear saturation mechanism (s) of these MHD waves and how such waves effect particle diffusion. An important part of this study involves using observed ring current ion distributions (from the A M P T E C C E Satellite) as input for the lower linear analysis to be able to determine the excitation mechanism (s) of ULF waves. This information along with a knowledge of the nonlinear saturation mechanism of ULF waves may provide important insight into the global dynamics of ring current plasmas.***//
