日冕物质抛射（CME）在太空天气中发挥着重要作用。日冕物质抛射在日冕和行星际空间中的传播特性决定了日冕物质抛射是否、何时以及如何撞击地球。为此，日冕物质抛射的观测和数值研究都取得了很多进展。随着先进观测、理论和数值方法的发展，关于日冕物质抛射的形态、运动学演化、到达1AU的预测以及加速/减速过程的研究不断涌现。此外，许多直接观测和模拟表明，日冕物质抛射可能不会在日冕和行星际空间中沿直线轨迹传播。观测和数值研究都表明，当两个或多个日冕物质抛射相互碰撞时，它们的运动特性可能会发生显着变化。在这里，我们回顾了与日冕物质抛射不同方面相关的最新进展，包括其行星际对应物ICME，特别关注日冕物质抛射的启动、日冕物质抛射的传播特性、与背景太阳风结构的相互作用、日冕物质抛射的偏转、连续日冕物质抛射之间的相互作用、与连续日冕物质抛射相互作用相关的粒子加速度以及复合事件对地球的影响。 磁层。
Coronal mass ejections (CMEs) play an important role in space weather. The propagation characteristics of CMEs in the Corona and interplanetary space determine whether, when and how the CME will hit the Earth. To this end, a lot of progress has been made both on observational and numerical studies of CMEs. With the development of the advanced observational, theoretical and numerical methods, there emerges more and more research on the morphology, the kinematic evolution, the prediction of the arrival at 1 AU and the acceleration/deceleration processes of CMEs. Moreover, many direct observations and simulations have revealed that the CMEs may not propagate along a straight trajectory both in the corona and interplanetary space. Both observational and numerical studies have shown that, when two or more CMEs collide with each other, their kinematic characteristics may change significantly. Here, we present a review of the recent progress associated with the different aspects of CMEs, including their interplanetary counterparts ICMEs, especially focusing on the initiation of the CME, the CMEs’ propagation characteristics, interaction with the background solar wind structures, the deflection of the CMEs, the interaction between successive CMEs, the particle acceleration associated with successive CMEs’ interaction, and the effect of compound events on Earth’s magnetosphere.
