Internal reconnection for northward interplanetary magnetic field
Bibliographic record
Abstract
On the basis of magnetohydrodynamic simulation results for northward interplanetary magnetic field (IMF) and significant dipole tilt, we describe internal reconnection processes that occur earthward of the magnetopause subsequent to magnetopause reconnection. We discuss the associated ionospheric signatures and show that the internal reconnection occurs not only between a summer lobe and a winter lobe field line but also between a summer lobe field line and a closed field line. The latter internal reconnection drives a pair of convection cells circulating outside the polar cap in the winter ionosphere. In this paper, we refer to these convection cells as “reciprocal cells” and the corresponding reconnection as reciprocal cell reconnection. The reciprocal cells are coupled to the so‐called lobe cells that are driven by magnetopause reconnection between an IMF line and a summer lobe field line (lobe cell reconnection); these lobe cells circulate inside the polar cap in the summer ionosphere. The reciprocal cell reconnection converts an overdraped lobe field line to a relaxed lobe field line, while the lobe cell reconnection converts a relaxed lobe field line to an overdraped lobe field line. Thus the reciprocal cell reconnection reciprocates with the lobe cell reconnection through the exchange of magnetic flux.

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.
