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）事件的性质和原因的数据分析和理论研究。 SMC是高磁性活性升高的扩展间隔，而无需发生实体。 该项目的目标是（1）通过将其特性与非SMC期间的特性进行比较，以进一步了解SMC，（2），以进一步了解我们对太阳能/磁层耦合的理解，通过使用SMC作为探测驱动SMC的特殊太阳风条件，（3），以进一步了解与替代运输相比，磁通量，能量和动量如何爆发的散装流量（BBF），以及（4）探索有关为什么SMC在下面发生的新想法某些太阳风条件。
