Planetary wave activity and rotational effects in the mid-latitudes of the lower and middle atmosphere (0-100KM)
Bibliographic record
Abstract
Investigation of the wind regime during solstices (1998-1999) allowed the presentation of the vertical structure of the intensity of planetary waves in the zonal and meridional wind. The seasonal dependence of the vertical structure of these planetary wave amplitudes is determined at middle atmosphere heights. Daily mesosphere/lower thermosphere (MLT) experimental data, measured at Collm (52N 15E, LF D1 radar), Kazan (56N 49E, meteor radar) and Saskatoon (52N 103W, MF radar) in the height range 80-100 km, and UKMO assimilated wind data from the British Atmospheric Data Center in the height range 0-55 km are used. In winter, maxima of the planetary wave intensity are observed near the tropopause and in the stratosphere. A decrease of the planetary wave intensity in the mesosphere coincides with the weakening of the stratospheric jet, and with the decay of the zonal flow in the mesosphere. Processes such as radiative suppression of planetary waves in the mesosphere and their additional reductions as a result of wave interactions and interactions with the zonal flow may explain these significant decreases of the intensity. Rotational spectra and estimates of rotational amplitudes in the height range of the middle atmosphere allow the investigation of the change of rotation direction of the horizontal wind vector dependent on height and period of the wave perturbations. © 2003 COSPAR.

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.
