理解并预测日冕物质抛射(CME)的地球效应,对保护近地空间和地面基础设施至关重要。本文提出一种新型融合模型,用于预测地球方向CME事件是否引发地磁暴。模型结合卷积神经网络进行特征学习,以及预测网络实现特征融合与事件分类。训练数据来自太阳和日球层观测卫星(SOHO)上的大角度光谱日冕仪(LASCO),以及太阳动力学观测卫星(SDO)上的大气成像组件(AIA)和日震与磁成像仪(HMI)。训练后的模型可预测地球直击型CME是否引发地磁暴及概率。基于五折交叉验证的实验结果表明,该模型在确定性预测中平均真技能统计(TSS)得分为0.703,在概率预测中平均布里尔得分(Brier score)为0.095。其中,TSS=1或布里尔得分为0代表完美性能。本研究有助于揭示太阳-地球相互作用中地球朝向CME与地磁暴之间的因果关系。

原文摘要 · Abstract (English)

Understanding and forecasting the geoeffectiveness of a coronal mass ejection (CME) is crucial for protecting infrastructure in the near-Earth space environment and on Earth. In this study, we present a novel fusion model to forecast the geoeffectiveness of CME events. Our model combines convolutional neural networks for feature learning and a prediction network for feature fusion and event classification. The model is trained by observations from instruments including the Large Angle Spectroscopic Coronagraph (LASCO) on board the Solar and Heliospheric Observatory (SOHO) and the Atmospheric Imaging Assembly (AIA) and Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO). The trained model is then used to predict whether an Earth-reaching CME will cause a geomagnetic storm and/or the probability that the CME will cause such a storm. Experimental results based on a five-fold cross validation scheme demonstrate the good performance of our fusion model, achieving a mean true skill statistic (TSS) score of 0.703 when the model is used as a deterministic prediction tool, and a mean Brier score of 0.095 when the model is used as a probabilistic forecasting tool, where a TSS score of 1 or a Brier score of 0 indicates perfect performance. This work contributes to forecasting the causal relationship between Earth-directed CMEs and geomagnetic storms in solar-terrestrial interactions.
