摘要

地磁暴（GSs）是太阳风中进入的等离子体喷出物与行星磁层之间的再连接过程造成的地面大气层中的重大扰动。最强的地磁效应甚至会导致低纬度地区出现极光，并造成卫星和地面基础设施故障。根据太阳光层的具体特征及早识别地球效应事件对于开发预警系统至关重要。在这项研究中，我们探讨了 SDO/HMI 仪器的空间-天气 HMI 活动区补丁（SHARP）数据库提供的 16 个磁场参数。分析包括在太阳周期（SC）24 和正在进行的 SC25 期间产生强 GS 的 64 个活动区。我们从皮尔逊和斯皮尔曼相关系数的角度介绍了SHARP和太阳参数之间的统计结果，并讨论了它们的空间气象潜力。

Parameter Study of Geoeffective Active Regions

Geomagnetic storms (GSs) are major disturbances in the terrestrial atmosphere caused by the reconnection process between the incoming plasma ejecta in the solar wind and the planetary magnetosphere. The strongest GSs can lead to auroral displays even at lower latitudes, and cause both satellite and ground-based infrastructure malfunctions. The early recognition of geoeffective events based on specific features on the solar photosphere is crucial for the development of early warning systems. In this study, we explore 16 magnetic field parameters provided by the Space-weather HMI Active Region Patch (SHARP) database from the SDO/HMI instrument. The analysis includes 64 active regions that produced strong GS during solar cycle (SC) 24 and the ongoing SC25. We present the statistical results between the SHARP and solar parameters, in terms of Pearson and Spearman correlation coefficients, and discuss their space weather potential.
