极光电离层是一个强烈的能量沉淀区。它最值得注意的影响是在极光椭圆中观察到的强烈发光。这种能量沉淀不太明显，但对磁层动力学至关重要，它导致电离层离子的强烈外流。在这一章中，我们提供了一个与极光离子外流相关的整个过程链的概述。我们讨论的过程，电离层离子的能量，从顶侧电离层到更遥远的磁层区域，和极光电离层流出的磁层动力学的影响。我们还将介绍最近对极光离子外流的观测。它们提供了其大规模空间分布，其对太阳和地磁活动的依赖，其时间动态及其与极光发射的联系的详细图片。© 2016美国地球物理联盟。All rights reserved.
The auroral ionosphere is a region of intense energy precipitation. Its most noteworthy effects are the intense luminous emissions observed in the auroral oval. Less visible but of primary importance for magnetospheric dynamics, this energy precipitation results in an intense outflow of ionospheric ions. In this chapter, we provide an overview of the whole chain of processes associated with auroral ion outflow. We discuss the processes that energize ionospheric ions, from the topside ionosphere to the more distant magnetospheric regions, and the effect of auroral ionospheric outflow on the magnetospheric dynamics. We will also present recent observations of auroral ion outflow. They provide a detailed picture of its large-scale spatial distribution, its dependence on solar and geomagnetic activity, its temporal dynamics, and its connection with auroral emissions. © 2016 by the American Geophysical Union.
