Influence of Indian Ocean Dipole on boreal summer intraseasonal oscillations in a coupled general circulation model
Bibliographic record
Abstract
The role of Indian Ocean Dipole (IOD) on poleward propagation of boreal summer intraseasonal oscillations (BSISO) is examined using long simulation of a coupled ocean‐atmosphere general circulation model. The model (SINTEX‐F1) simulates the salient features of BSISO realistically. It is found that coherent (incoherent) poleward propagation of precipitation anomalies from 5°S to 25°N are observed during negative (positive) IOD years. The probable mechanisms behind such an anomaly in poleward propagation of BSISO in contrasting IOD years are identified. We find that the mean structure of meridional specific humidity distribution undergoes cardinal changes in contrasting IOD years, which in turn influences the meridional propagation of BSISO. Enhanced (decreased) air‐sea interaction in negative (positive) IOD years also supports coherent (incoherent) poleward propagation of BSISO anomalies. This study has important implications, considering the critical role of BSISO in modulating the seasonal mean summer monsoon rainfall.

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.
