On the dependence of storm time ULF wave power on magnetopause location: Impacts for ULF wave radial diffusion
Bibliographic record
Abstract
Abstract Ultralow frequency (ULF) waves play a crucial role in energetic particle dynamics in the inner magnetosphere. We examine the role of the magnetopause location in controlling the amplitude and penetration of ULF waves within the inner magnetosphere during 63 coronal mass ejection (CME)‐driven and corotating interaction region (CIR)‐driven geomagnetic storms. Significantly, at the time when the magnetopause is most compressed, ULF wave power increases and penetrates to the deepest L shells. Most likely this is explained by proximity to the energy source and accumulation of energy within a smaller volume through solar wind‐magnetopause‐magnetosphere coupling, and changes in the storm time Alfvén continuum resulting from variations in the cold plasma density. The observed ULF wave power is consistently larger than Kp ‐dependent statistical estimates—especially in the heart of the outer radiation belt. This has important implications for radiation belt dynamics, including main phase loss and storm time ULF wave radial diffusion.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
