Auroral Dynamics in Relation to Magnetospheric Processes

研究人员将继续执行一项关于地球磁层形态和动态的研究方案，重点是极光电离层区域与遥远磁层区域之间的动态联系。 研究课题包括（1）极光椭圆形、共轭性和对行星际磁场的依赖性，（2）昼侧极光现象，（3）地球同步亚暴现象，以及（4）中磁层在驱动极光弧电流中的作用。 这些研究将利用DMSP和POLAR卫星数据以及地球同步卫星数据（如果可用）。 这些研究的一个共同主题是，中磁层在离散极光现象中发挥着更为重要的作用。

The investigators will continue a program of research on the morphology and dynamics of Earth's magnetosphere, focussing on the dynamic connection between auroral ionospheric regions and distant magnetospheric regions. Research topics include (1) auroral oval shape, conjugacy and dependence on the interplanetary magnetic field, (2) dayside auroral phenomena, (3) geosynchronous substorm phenomena, and (4) the role of the middle magnetosphere in driving auroral arc currents. The studies will make use of DMSP and POLAR satellite data, and geosynchronous satellite data when available. A common theme in these studies is that the middle magnetosphere has a much more important role to play in discrete auroral phenomena.
