Abstract

fetched live from OpenAlex

Pronounced filamentation of tropospheric and stratospheric air masses was observed on a flight in the vicinity of the polar jet stream during the STREAM 1998 campaign in Timmins, Canada. High‐spatial resolution O 3 and H 2 O measurements showed highly variable structures for the investigated region. Reconstructing high‐resolution potential vorticity (PV) fields using the reverse‐domain‐filling (RDF) technique reproduce the in‐situ O 3 measurements qualitatively. Measurements and RDF results show the intrusion of stratospheric air penetrating deep into the troposphere. The observed intrusions occur on smaller horizontal scales than generally assumed for tropopause folding events. Moreover, fine‐scale structures of tropospheric air masses being lifted up into the stratosphere could be reconstructed by the RDF technique using the tropospheric tracer specific humidity in addition to the more conventional calculations for the stratospheric tracer PV.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
