The interchange cycle: A fundamental mode of magnetic flux circulation for northward interplanetary magnetic field
Bibliographic record
Abstract
The interchange cycle is a mode of magnetic flux circulation that dominates when the interplanetary magnetic field (IMF) clock angle (θc ≡ atan2(BY, BZ)) lies in the range of ∣θc∣ 30°. It consists of IMF‐lobe reconnection in one hemisphere and lobe‐closed reconnection in the other hemisphere, producing in the ionosphere an interchange‐type merging cell in the former hemisphere and a reciprocal cell in the latter hemisphere. For a given IMF clock angle and a given dipole tilt angle, there usually exist two independent interchange cycles. Thus the two interchange cycles drive twin reverse cells in both hemispheres, but the category of each reverse cell (either an interchange‐type merging cell or a reciprocal cell) depends on the given conditions. In this paper, we demonstrate how the reverse cell pattern changes systematically depending on the IMF orientation and the dipole tilt.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
