This study investigates individual and combined impacts of BSISO and ENSO on the SSD intensity over TWNP. It is found that the impact of the BSISO wet phase on the SSD intensity is pronouncedly different in El Niño and La Niña years, whereas the SSD intensity in the BSISO dry phase is relatively less sensitive to ENSO. El Niño and La Niña induce different SSD intensity changes in the BSISO wet phase. El Niño leads to an increase and eastward shift of large SSD intensity. This is attributed to the increase and eastward shift of cyclonic lower-level wind fields and consequently the barotropic energy conversion from background lower-level wind fields to SSDs. La Niña leads to an increase and northward shift of large SSD intensity. This results from a shift of cyclonic lower-level wind fields and associated barotropic energy conversion from background lower-level wind fields to SSDs to northwestern TWNP. In the BSISO dry phase, the background lower-level wind fields are anticyclonic and the ENSO effects are small due to unfavorable background field. This accounts for the relatively small ENSO effect on the SSD intensity in the BSISO dry phase.</p>","PeriodicalId":15986,"journal":{"name":"Journal of Geophysical Research: Atmospheres","volume":"131 20","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149206136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to mean radiative fluxes, LW scattering can also change radiative sensitivities as quantified by radiative kernels. This aspect of the LW scattering effect, especially on the radiative sensitivity of non-cloud variables, has remained largely unexplored. In this study, we use the Canadian Atmospheric Model (CanAM) which accounts for LW scattering to investigate how it affects broadband and spectral flux radiative kernels and subsequently biases kernel-diagnosed climate feedbacks. Our results show that LW scattering generally weakens the non-cloud kernels, reducing the sensitivity of TOA and surface radiative fluxes to non-cloud feedback variables, with the reduction being stronger at the TOA than at the surface. The largest impact occurs in the water vapor TOA kernel, especially in the far-infrared region. Consistent with these radiative kernel changes, non-cloud radiative feedbacks diagnosed using radiative kernels are weaker when LW scattering is included. On the other hand, the cloud feedback is enhanced, corroborating earlier findings.</p>","PeriodicalId":15986,"journal":{"name":"Journal of Geophysical Research: Atmospheres","volume":"131 20","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2026JD046597","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present a machine learning framework that objectively detects meteorological seasons and projects their future evolution. The method combines Radially Constrained Clustering (RCC) to identify seasons from reanalysis data with a supervised Multinomial Logistic Regression Classifier (MLRC) that allows these definitions to be applied also to climate model projections. We use the Indian subcontinent as a detailed proof of concept region since it has established operational references for monsoon onset and withdrawal, and it includes contrasting seasonal regimes, from monsoon dominated lowlands to high mountain regions influenced by winter disturbances. The RCC-derived seasons recover the main operational seasonal phases adopted by the India Meteorological Department, while also providing consistent definitions of transition periods. Evaluation against a CMIP6 multi-model ensemble shows that models capture the seasonal cycle with high skill in Central and Southern India, but exhibit lower performance in complex mountainous regions. Future projections indicate a robust lengthening of the monsoon season, primarily due to delayed withdrawal, and a concurrent shortening of winter, driven by the loss of days in December–January.

However, current operational retrieval pipelines typically rely on physically-based matched filters followed by labor-intensive manual verification to mitigate high false alarm rates caused by complex background interference. This dependence on human intervention restricts the scalability and efficiency required for rapid, automated global monitoring. To address these limitations, this paper proposes Plume-Net, a novel Physics-Informed Guided Two-Stage Retrieval Method. Unlike conventional approaches, Plume-Net decouples the task into a “global existence classification” stage and a “local pixel-level regression” stage to maximize reliability without human-in-the-loop. The core innovation lies in the integration of physical priors with deep learning: In the first stage, a Physics-Informed Spectral Gating (PISG) module explicitly injects methane spectral absorption knowledge into the network, dynamically recalibrating channel weights to suppress background noise. In the second stage, to overcome the difficulties of regressing sparse, long-tail plume distributions, we propose a Plume-Focused Sampling Strategy and an Intensity-Aware Pixel-Level Weighted Loss function, forcing the network to prioritize rare but critical high-concentration signals. Evaluated on real-world EMIT observations, Plume-Net achieves an ROC-AUC of 0.961 in detection and a Mean Absolute Error (MAE) of 33.33 ppm·m in quantification. By significantly reducing false positives while maintaining high precision, this method offers a robust, fully automated alternative to current semi-manual retrieval workflows.</p>","PeriodicalId":15986,"journal":{"name":"Journal of Geophysical Research: Atmospheres","volume":"131 20","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate the ability of the 9-month Climate Forecast System Version 2 (CFSv2) operational forecast to represent near surface SM at forecast lead times (LTs) from hours to weeks over the Gulf coast TC landfalling region. Our results show that the decrease in the predictability of SM and associated precipitation with LTs not only appears at relatively short timescales (e.g., weekly or shorter events), but also evident in the interannual variability and long term (7-year) mean climatology. Moreover, the spatial biases increase with the LT at about one to 2 weeks and act to damp the spatial variability. Nevertheless, even at shorter LTs (i.e., hours to days), the forecasted precipitation fails to capture the more intense events, which contributes to biases in the SM at all LTs. Our results assess the relationship between the predictability of the SM and the related precipitation with LTs. The results suggest that CFSv2 is unlikely to capture the influence of antecedent SM variability associated with preceding convective events on subsequent events (e.g., evaluation of TCs after landfall) on LTs longer than a week, which has implications for overall subseasonal-to-seasonal predictability.</p>","PeriodicalId":15986,"journal":{"name":"Journal of Geophysical Research: Atmospheres","volume":"131 20","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2026JD046700","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
