用Exascale计算进行空间天气预报
Space Weather Prediction with Exascale Computing
摘要：
空间天气系指太阳、行星际空间和地球空间环境中可能影响空间和地面技术系统的性能和可靠性并可能危及人类生命或健康的条件。空间环境中的不利条件可造成卫星运行、通信、导航和电功率配电网中断，导致各种社会经济损失。太空中的条件也与地球气候有关。太阳的活动影响到达地球的热和光的总量以及到达大气层的宇宙射线的数量，这一现象与云层和降水量有关。鉴于这些对社会的巨大影响，空间天气正引起越来越多的关注，并成为全世界国际努力的主题。我们在此侧重于实现真正的基于物理学的能力以预测重大空间天气风暴的到来和后果所需的步骤。空间环境中的大扰动是常见的，但其确切到达时间和对人类活动的影响差异很大。模拟这样一个系统是一个巨大的挑战，需要计算资源的极限是什么，不仅与目前的技术，而且与可预见的未来几代超级计算机
英文摘要：
Space weather refers to conditions on the Sun, in the interplanetary space and in the Earth space environment that can influence the performance and reliability of space-borne and ground-based technological systems and can endanger human life or health. Adverse conditions in the space environment can cause disruption of satellite operations, communications, navigation, and electric power distribution grids, leading to a variety of socioeconomic losses. The conditions in space are also linked to the Earth climate. The activity of the Sun affects the total amount of heat and light reaching the Earth and the amount of cosmic rays arriving in the atmosphere, a phenomenon linked with the amount of cloud cover and precipitation. Given these great impacts on society, space weather is attracting a growing attention and is the subject of international efforts worldwide. We focus here on the steps necessary for achieving a true physics-based ability to predict the arrival and consequences of major space weather storms. Great disturbances in the space environment are common but their precise arrival and impact on human activities varies greatly. Simulating such a system is a grand- challenge, requiring computing resources at the limit of what is possible not only with current technology but also with the foreseeable future generations of super computers
