The Principal Investigator's (PI's) team will assess the relationship between solar subsurface mass flows and the production of flares and coronal mass ejections (CMEs) from solar active regions. To accomplish this, the team will utilize local helioseismology techniques to probe the mass flows beneath magnetic fields observed at the surface of the Sun which may be associated with eruptive events. The PI's team will determine differences in the subsurface flows between active regions associated with eruptive flares and quiescent active regions, validate the reliability of the subsurface flows that they detect, link subsurface flows and flare productivity through comparisons of observed flows with those predicted by models, and independently assess and potentially improve subsurface kinetic-helicity-based flare forecasting indices recently proposed by other researchers. This team's theoretical predictions will lead to improved physical understanding of the relationship between subsurface flows, as well as and the magnetic properties of CME-eruptive and flare-eruptive solar active regions. The broader impacts of this work will come from making solar flare and CME forecasting more accurate, thereby directly benefitting society. This study could lead to the ability to accurately predict the occurrence of flares and CMEs with up to several days warning.

首席研究员（PI）团队将评估太阳能质量流量与太阳能活动区域的耀斑和冠状质量弹出（CME）之间的关系。为此，团队将利用局部的Helioseology技术来探测在太阳表面观察到的磁场下的质量流，这可能与喷发事件有关。 PI的团队将确定与喷发和静态活跃区域相关的活动区域之间的地下流的差异，从而通过比较观察到的流量通过模型和潜在的基于基础基于基础曲线的指标来验证其检测到的地下流，链接地下流量和Flare生产力的可靠性。该团队的理论预测将导致对地下流之间的关系以及CME爆发和爆发的太阳活性区域的磁性以及磁性的物理理解。这项工作的更广泛的影响将来自使太阳耀斑和CME预测更准确，从而直接使社会受益。这项研究可能会导致能够准确预测耀斑和CME的发生，并警告几天。
