Abstract

The term space weather refers to conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-borne and ground-based technological systems and that can affect human life and health. Our modern hi-tech society has become increasingly vulnerable to disturbances from outside the Earth system, in particular to those initiated by explosive events on the Sun: Flares release flashes of radiation that can heat up the terrestrial atmosphere such that satellites are slowed down and drop into lower orbits, solar energetic particles accelerated to near-relativistic energies may endanger astronauts traveling through interplanetary space, and coronal mass ejections are gigantic clouds of ionized gas ejected into interplanetary space that after a few hours or days may hit the Earth and cause geomagnetic storms. In this review, I describe the several chains of actions originating in our parent star, the Sun, that affect Earth, with particular attention to the solar phenomena and the subsequent effects in interplanetary space.

太空天气:太阳的视角
空间天气一词是指太阳和太阳风、磁层、电离层和热层中能够影响星载和地面技术系统的性能和可靠性并能够影响人类生命和健康的条件。我们的现代高科技社会越来越容易受到来自地球系统外的干扰,特别是那些由太阳爆炸事件引发的干扰。耀斑释放出的辐射会使地球大气升温,从而使卫星减速并落入较低的轨道;太阳高能粒子加速到接近相对论的能量,可能危及在行星际空间旅行的宇航员;日冕物质抛射是被抛射到行星际空间的巨大电离气体云,在几小时或几天后可能撞击地球并引起地磁风暴。在这篇综述中,我描述了起源于我们的母星太阳的影响地球的几条行动链,特别关注太阳现象及其对行星际空间的后续影响。
