This project involves a data-analysis and theoretical investigation into the properties and causes of steady magnetospheric convection (SMC) events. SMCs are extended intervals of elevated geomagnetic activity without the occurrence of substorms. The objectives of this project are (1) to further our understanding of SMCs by statistically comparing their properties with the properties of non-SMC periods, (2) to further our understanding of solar-wind/magnetosphere coupling by using SMCs as a probe of the special solar wind conditions that drive SMCs, (3) to further our understanding of how bursty bulk flows (BBfs) transport magnetic flux, energy and momentum in comparison with substorm transport, and (4) to explore new ideas about why SMCs occur under certain solar wind conditions.

该项目涉及对稳定磁层对流（SMC）事件的性质和原因进行数据分析和理论研究。 SMC是地磁活动增强的延长间隔，但没有亚暴的发生。 本项目的目标是：（1）通过统计比较SMC与非SMC周期的性质，进一步了解SMC的性质;（2）通过使用SMC作为驱动SMC的特殊太阳风条件的探测器，进一步了解太阳风/磁层耦合;（3）进一步了解突发体流（BBfs）如何传输磁通量，能量和动量与亚暴传输的比较，以及（4）探索为什么SMC在某些太阳风条件下发生的新想法。
