Abstract
We have been observing vertical winds in the polar thermosphere with a Fabry-Perot interferometer (FPI) installed at Poker Flat Research Range, Alaska. To introduce a new method to understand thermospheric wind system in the polar region, the vertical wind variations are compared with the peak location of ionospheric current deduced from magnetic field measurements on the ground in a case observed on December 5, 1999. The magnetometer data were obtained at Kaktovik, Fort Yukon, Poker Flat, and Gakona. The method of estimating ionospheric current was obtained from H. Luhr et al. (J. Atmos. Terr. Phys., 56, 81, 1994). The eastward current dominant interval was clearly separated from the westward current dominant one at 1130 UT (～0030 MLT) in this case. The relation between the vertical wind and the location of the ionospheric current was clearly different before and after the boundary. Namely, the downward (upward) vertical wind was found to be dominant equatorward (poleward) of the ionospheric current after 1130 UT, which is consistent with results obtained in many previous works. However, this relation was found to be opposite before 1130 UT: the upward (downward) vertical wind was seen to be equatorward (poleward) of current.

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 it
