地球磁尾相干磁结构和爆发体流的优先加速
Preferential Acceleration of Coherent Magnetic Structures and Bursty Bulk Flows in Earth's Magnetotail
摘要：
观测结果表明，磁尾对流是湍流和双峰，包括快速爆发的整体流（BBF）和一个几乎停滞的背景。我们证明，这一观察到的现象可以理解的间歇性相互作用，动态合并和优先加速的相干磁结构的影响下的背景磁场几何形状是一致的X点平均场结构的发展。
英文摘要：
Observations indicate that the magnetotail convection is turbulent and bi-modal, consisting of fast bursty bulk flows (BBF) and a nearly stagnant background. We demonstrate that this observed phenomenon may be understood in terms of the intermittent interactions, dynamic mergings and preferential accelerations of coherent magnetic structures under the influence of a background magnetic field geometry that is consistent with the development of an X-point mean-field structure.
