This project will examine the different magneto-hydrodynamic wave modes in the magnetosphere. Four interrelated topics will be studied: (1) The relationship of ULF waves to the energization of particles in the radiation belts, (2) resonant cavity modes in the inner magnetosphere, (3) excitation of field-line resonance modes by energetic ring current particles, and (4) the effects of pressure anisotropy on the plasma dynamics of the inner magnetosphere. The methods used to study these questions will include analysis of satellite and ground-based data, MHD and gyrokinetic simulations, and anisotropic MHD simulations coupled to hybrid code simulations.

本项目将研究磁层中不同的磁流体动力波模式。 将研究四个相互关联的主题：（1）超低频波与辐射带中粒子的相互作用的关系，（2）内磁层中的谐振腔模式，（3）高能环电流粒子对场线谐振模式的激发，以及（4）压力各向异性对内磁层等离子体动力学的影响。 用于研究这些问题的方法将包括分析卫星和地面数据，MHD和陀螺动力学模拟，以及各向异性MHD模拟耦合到混合代码模拟。
