Integrity review: Wind Variability at Synoptic-to-Planetary Frequencies Enhances Front Asymmetry of Mesoscale Eddy (JPO, 2026)

Academic fraud report · Geng Detector

Summary

Verdict: The paper is judged CLEAN. No indicators of academic misconduct were found. A full review of the submission timeline, numerical model configuration, physical parameters, and reported numerical values found all elements internally consistent and physically reasonable. The submission-to-acceptance timeline of approximately six months is normal, not a 'flash-publication' anomaly. CROCO model setup (1.5 km parent, 500 m child grid, 50 vertical levels), Coriolis parameter (~4.5e-5 s^-1), eddy radius (100 km) and depth (375 m) are all within typical South China Sea ranges. Specific values such as 1.583e-7 and 1.623e-7 s^-2 are irregular to the third decimal, consistent with genuine model output rather than fabricated data. Limitations: pixel-level image forensics was not possible from text-only input, and the merged author string 'BOYANWU ANDZHIYOUJING' is almost certainly a PDF parsing artifact. Overall confidence is moderate-to-high for non-image-related concerns.

Verdict

Clean. No evidence of academic fraud detected.

Key findings

Submission timeline (received 5 Sep 2025; final 25 Dec 2025; accepted 12 Mar 2026; ~6-month cycle) is normal and not indicative of rushed or bulk publication.
Publication in June 2026 with a download watermark of 05/07/26 is consistent with an Early Access article; no temporal inconsistency.
Reference to Tang et al. 2025 in a 2026 paper is appropriate and current.
Model configuration (CROCO, 1.5 km / 500 m horizontal grids, 50 vertical levels) is standard for mesoscale–submesoscale interaction studies.
Physical parameters ($f \approx 4.5 \times 10^{-5} \, s^{-1}$, eddy radius 100 km, depth 375 m) match typical South China Sea anticyclonic eddy conditions.
Reported values (e.g., $1.583 \times 10^{-7}$ to $1.623 \times 10^{-7} \, s^{-2}$) are irregular to three decimals, consistent with raw NetCDF-derived output rather than fabricated numbers.
Appendix derivations of the divergence diagnostic are coherent and physically interpretable.
Figure captions and figure-content descriptions in the text are mutually consistent and conform to Ekman-transport-based physical expectations (e.g., EBF sign distribution in Fig. 5).

Evidence highlights

DOI: 10.1175/JPO-D-25-0203.1
Specific numerical example: frontal $|\nabla b|$ increased from $1.583 \times 10^{-7}$ to $1.623 \times 10^{-7} \, s^{-2}$.
Timeline dates: received 2025-09-05, final 2025-12-25, accepted 2026-03-12.
Grid hierarchy: 1.5 km parent, 500 m child, 50 vertical levels.
Region implied by $f \approx 4.5 \times 10^{-5} \, s^{-1}$: South China Sea (~18°N).

Notes

Image-pixel-level duplication or manipulation analysis could not be performed because only text was provided; this is the primary residual limitation of the review.
The concatenated author string 'BOYANWU ANDZHIYOUJING' is most likely a PDF-to-text parsing artifact ('Boyan Wu and Zhiyou Jing'), not an authorial or typesetting issue.
The reviewer notes that numerical-model papers are intrinsically harder to fabricate because they require self-consistent code output; however, this does not eliminate all risk and pixel-level checks remain advisable if figures become available.
This report is AI-assisted and intended for academic discussion only; final determinations of misconduct require institutional investigation.
