F10.7 Index Prediction: A Multiscale Decomposition Strategy with Wavelet Transform for Performance Optimization
Xuran Ma, Xuebao Li, Yanfang Zheng +15
In this study, we construct Dataset A for training, validation, and testing, and Dataset B to evaluate generalization. We propose a novel F10.7 index forecasting method using wavel…
Prediction of Major Solar Flares Using Interpretable Class-dependent Reward Framework with Active Region Magnetograms and Domain Knowledge
Zixian Wu, Xuebao Li, Yanfang Zheng +14
In this work, we develop, for the first time, a supervised classification framework with class-dependent rewards (CDR) to predict MM flares within 24 hr. We construct multipl…
Operational Solar Flare Forecasting System Using an Explainable Large Language Model
Xuebao Li, Yongshang Lv, Jinfang Wei +14
This study focuses on forecasting major (>=M-class) solar flares that can severely impact the near-Earth environment. We construct two types of datasets using the Space Weather HMI…
Prediction of Large Solar Flares Based on SHARP and HED Magnetic Field Parameters
Xuebao Li, Xuefeng Li, Yanfang Zheng +7
The existing flare prediction primarily relies on photospheric magnetic field parameters from the entire active region (AR), such as Space-Weather HMI Activity Region Patches (SHAR…
Survey of Magnetic Field Parameters Associated With Large Solar Flares
Ting Li, Yanfang Zheng, Xuefeng Li +4
Until now, how the magnetic fields in M/X-class flaring active regions (ARs) differ from C-class flaring ARs remains unclear. Here, we calculate the key magnetic field parameters w…
