摘要

驱动太空天气的自由能是在太阳的对流区产生的,伴随着磁场的产生和对流扭曲。这些磁场上升到地表,在那里它们提供了强烈的超热活动,这是太空天气的直接来源。流体力学和磁场产生的某些方面已被理解,但仍有许多是神秘的。这个谜团的一个重要部分是围绕着对流区复杂的流体动力学和主要的微尺度磁纤维结构、运动和表面的相互作用。下一代先进太阳望远镜——太阳显微镜——旨在打开这个基本的小规模世界,进行直接观测研究。另一个主要的谜团在于太阳活动总体水平的长期变化,以及与之相关的空间天气和陆地气候的变化。不幸的是,长期变化只能在长期内进行研究,尽管迄今为止对其他类太阳恒星的监测有助于提出极端的可能性。

Space Weather and the Changing Sun
The free energy that drives space weather is created in the convective zone of the Sun with the generation and convective distortion of magnetic fields. The fields rise to the surface where they provide the vigorous suprathermal activity that is the direct parent of space weather. Some aspects of the hydrodynamics and magnetic field generation are understood, while there remains much that is mysterious. An important part of the mystery centers around the complex hydrodynamics of the convective zone and the dominating micro-scale magnetic fibril structure, motion, and interactions at the surface. The next generation Advanced Solar Telescope-the solar microscope- is intended to open up this basic small-scale world to direct observational study. The other major mystery lies in the long- term variations in the general level of solar activity, with the associated variations in space weather and terrestrial climate. Unfortunately long-term variation can be studied only in the long term, although monitoring other solar-type stars has been helpful so far in suggesting the extreme possibilities.

期刊介绍: Space Weather: The International Journal of Research and Applications (SWE) is devoted to understanding and forecasting space weather. The scope of understanding and forecasting includes: origins, propagation and interactions of solar-produced processes within geospace; interactions in Earth’s space-atmosphere interface region produced by disturbances from above and below; influences of cosmic rays on humans, hardware, and signals; and comparisons of these types of interactions and influences with the atmospheres of neighboring planets and Earth’s moon. Manuscripts should emphasize impacts on technical systems including telecommunications, transportation, electric power, satellite navigation, avionics/spacecraft design and operations, human spaceflight, and other systems. Manuscripts that describe models or space environment climatology should clearly state how the results can be applied.
