论文摘要
太阳火光是太阳上最严重的太阳能活动之一，它对近地空间产生了许多重要的影响。已经发现，在太阳耀斑期间，飞行延迟将增加。但是，太阳耀斑如何影响延迟的详细固有机制仍然未知。根据5年的大量飞行数据，我们在这里全面分析了57个太阳能耀斑期间的飞行延迟。发现与安静期间相比，太阳耀斑期间的平均飞行延迟时间增加了20.68％（7.67分钟）。还表明，与太阳耀斑相关的飞行延迟揭示了明显的时间和纬度依赖性。几天的太阳耀斑的飞行延误比夜间耀斑中的飞行更严重，并且较长（较小）延迟往往会发生在较低（较高）的纬度机场。进一步的分析表明，飞行延迟时间和延迟速率将通过太阳强度（软X射线通量）和太阳天顶角直接调节。这些结果首次表明，太阳耀斑引起的沟通干扰将直接影响飞行偏离时间和延迟速率。这项工作还将我们的传统理解扩展到太阳耀斑对人类社会的影响，它还可以为我们提供全新的观点，以帮助预防或应对飞行延误。
Solar flare is one of the severest solar activities on the sun, and it has many important impacts on the near-earth space. It has been found that flight arrival delays will increase during solar flare. However, the detailed intrinsic mechanism of how solar flares influence the delays is still unknown. Based on 5-years huge amount of flight data, here we comprehensively analyze the flight departure delays during 57 solar flares. It is found that the averaged flight departure delay time during solar flares increased by 20.68% (7.67 min) compared to those during quiet periods. It is also shown that solar flare related flight delays reveal apparent time and latitude dependencies. Flight delays during dayside solar flares are more serious than those during nightside flares, and the longer (shorter) delays tend to occur in the lower (higher) latitude airport. Further analyses suggest that flight delay time and delay rate would be directly modulated by the solar intensity (soft X-ray flux) and the Solar Zenith Angle. For the first time, these results indicate that the communication interferences caused by solar flares will directly affect flight departure delay time and delay rate. This work also expands our conventional understandings to the impacts of solar flares on human society, and it could also provide us with brand new views to help prevent or cope with flight delays.
