Our experiment designs are motivated by land‐ocean heterogeneity of atmospheric convection. The steady and oscillating forcings are idealizations of ocean and land conditions, respectively, based on their differences in heat capacities. In both kinds of simulations, the diurnal mean SST and SOLIN are the same, and both SST and SOLIN are only varied in time (i.e., they are spatially homogeneous at any given time). We find that diurnally oscillating forcing accelerates CSA. Stronger long‐wave cooling in dry regions at night and during the warm SST phase (late afternoon) both allow the long‐wave feedback, known to favor aggregation, to intensify compared to steady forcing simulations. In addition to the long‐wave, reduced short‐wave warming in dry regions (during the day) further enhances radiative cooling there compared to moist regions. Overall, the radiative cooling is enhanced in dry regions compared to neighboring moist convective regions. A dry subsidence is driven by this net radiative (short‐wave plus long‐wave) cooling, consistent with earlier work on CSA. Stronger radiative cooling allows stronger subsidence which allows low‐level circulation to more efficiently transport moisture and energy up‐gradient, driving convection to aggregate faster. We also note a sensitivity of our experimental setup to initial conditions, more so at warmer SST. This stochastic behavior might be critical in reconciling the differences of opinion regarding the response of convection aggregation to oscillating SST forcing.","lang":"eng"}],"date_published":"2026-01-12T00:00:00Z","article_processing_charge":"Yes","publication":"Journal of Advances in Modeling Earth Systems","acknowledged_ssus":[{"_id":"ScienComp"}],"doi":"10.1029/2024ms004576","acknowledgement":"The authors gratefully acknowledge funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program (Project CLUSTER, Grant Agreement No. 805041).

For the monsoons, which are exceptions in this regard, we found northeast India often gets excess pre-monsoon rainfall. Further investigation reveals that this excess pre-monsoon rainfall is produced by the interaction of the large-scale circulation associated with the joint phase with the mountains in northeast India. We posit that a warmer troposphere, a consequence of excess rainfall over northeast India, drives a stronger monsoon circulation and enhances monsoon rainfall over central India. Hence, we argue that pre-monsoon rainfall over northeast India can be used for seasonal monsoon rainfall prediction over central India. Most importantly, its predictive value is at its peak when the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought monsoon looms over India.","lang":"eng"}],"intvolume":"        51","year":"2024","acknowledgement":"The author gratefully acknowledges ISTA for supporting this research through funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Project CLUSTER, grant agreement No. 805041).","article_number":"e2023GL106569","volume":51,"oa_version":"Published Version","ddc":["550"],"project":[{"call_identifier":"H2020","grant_number":"805041","_id":"629205d8-2b32-11ec-9570-e1356ff73576","name":"Organization of CLoUdS, and implications of Tropical  cyclones and for the Energetics of the tropics, in current and waRming climate"}],"DOAJ_listed":"1","corr_author":"1","date_created":"2024-03-24T23:00:58Z","publication_status":"published","OA_type":"gold","has_accepted_license":"1","author":[{"id":"3a4ac09c-6d61-11ec-bf66-884cde66b64b","orcid":"0000-0001-8602-3083","last_name":"Goswami","full_name":"Goswami, Bidyut B","first_name":"Bidyut B"}],"scopus_import":"1","external_id":{"isi":["001181635700001"]},"language":[{"iso":"eng"}],"day":"16","OA_place":"publisher","oa":1,"publication_identifier":{"eissn":["1944-8007"],"issn":["0094-8276"]},"file":[{"content_type":"application/pdf","access_level":"open_access","file_name":"2024_GeophysResLetters_Goswami.pdf","date_updated":"2024-03-25T08:36:00Z","creator":"dernst","checksum":"243bd966aca968ec7d9e474af8639f8d","date_created":"2024-03-25T08:36:00Z","relation":"main_file","file_size":2887134,"file_id":"15178","success":1}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345"},{"date_created":"2024-12-29T23:01:57Z","DOAJ_listed":"1","ddc":["550"],"article_number":"305","oa_version":"Published Version","volume":7,"acknowledgement":"This study was supported by the National Research Foundation of Korea (NRF) grant funded by the Korean government (MSIT) (NRF-2018R1A5A1024958, NRF-2021R1C1C2094185, RS-2024-00336160).

Following CO2 removal, monsoon circulation weakens throughout the summer owing to the reduced large-scale meridional temperature gradient around India. Weakened monsoon circulation decreases the local-scale thermodynamic stability within India, following monsoon-onset periods. While the frequency of synoptic-scale ISM low-pressure systems (LPSs) decreases overall, the lower thermodynamic stability causes the LPSs to form and resultantly shift west and south from their typical paths, last longer and move more quickly zonally during August and September. Changes in these rain-producing processes induce distinct regional (Western Ghats, south-central-east India, and Tamil Nadu) and subseasonal precipitation responses. Also, extreme precipitation exhibits similar patterns, but is more strongly affected by changes in LPS. Our results suggest that reliable future projections of regional hydroclimate change require a more accurate understanding of multi-scale precipitation processes."}],"doi":"10.1038/s41612-024-00858-0","article_processing_charge":"Yes","publication":"npj Climate and Atmospheric Science","date_published":"2024-12-19T00:00:00Z","file":[{"creator":"dernst","date_updated":"2025-01-02T08:49:13Z","access_level":"open_access","content_type":"application/pdf","file_name":"2024_npjclimate_Paik.pdf","checksum":"6b3148315a444835113c32b399010370","file_size":1927871,"relation":"main_file","date_created":"2025-01-02T08:49:13Z","success":1,"file_id":"18717"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","language":[{"iso":"eng"}],"day":"19","publication_identifier":{"eissn":["2397-3722"]},"oa":1,"OA_place":"publisher","author":[{"last_name":"Paik","first_name":"Seungmok","full_name":"Paik, Seungmok"},{"last_name":"Kim","full_name":"Kim, Daehyun","first_name":"Daehyun"},{"last_name":"An","first_name":"Soon Il","full_name":"An, Soon Il"},{"last_name":"Oh","full_name":"Oh, Hyoeun","first_name":"Hyoeun"},{"last_name":"Shin","first_name":"Jongsoo","full_name":"Shin, Jongsoo"},{"orcid":"0000-0001-8602-3083","id":"3a4ac09c-6d61-11ec-bf66-884cde66b64b","first_name":"Bidyut B","full_name":"Goswami, Bidyut B","last_name":"Goswami"},{"last_name":"Min","first_name":"Seung Ki","full_name":"Min, Seung Ki"},{"full_name":"Mondal, Sanjit Kumar","first_name":"Sanjit Kumar","last_name":"Mondal"}],"scopus_import":"1","external_id":{"isi":["001381218300007"]},"OA_type":"gold","publication_status":"published","has_accepted_license":"1","type":"journal_article","month":"12","status":"public","title":"Exploring causes of distinct regional and subseasonal Indian summer monsoon precipitation responses to CO2 removal","publisher":"Springer Nature","_id":"18708","isi":1,"tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)"},"department":[{"_id":"CaMu"}],"quality_controlled":"1","article_type":"original","date_updated":"2025-09-09T11:51:56Z","citation":{"short":"S.

However, since 2002 it is reported to have revived. For these observed changes in the ISMR, several explanations have been reported. Among these explanations, however, the role of the eastern equatorial Indian Ocean (EEIO) is missing despite being one of the warmest regions in the Indian Ocean, and monotonously warming. A recent study reported that EEIO warming impacts the rainfall over northern India. Here we report that warming in the EEIO weakens the low-level Indian summer monsoon circulation and reduces ISMR. A warm EEIO drives easterly winds in the Indo–Pacific sector as a Gill response. The warm EEIO also enhances nocturnal convection offshore the western coast of Sumatra. The latent heating associated with the increased convection augments the Gill response and the resultant circulation opposes the monsoon low-level circulation and weakens the seasonal rainfall."}],"intvolume":"        60","year":"2023","acknowledgement":"This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIT) (NRF-2018R1A5A1024958).

We find a monotonous weakening of the ENSO-monsoon teleconnection with the increase in CO2. Increased co-occurrences of El Niño and positive Indian Ocean Dipoles (pIODs) in a warmer climate weaken the teleconnection. Co-occurrences of El Niño and pIOD are attributable to mean sea surface temperature (SST) warming that resembles a pIOD-type warming pattern in the Indian Ocean and an El Niño-type warming in the Pacific. Since ENSO is a critical precursor of the strength of the Indian monsoon, a weakening of this relation may mean a less predictable Indian monsoon in a warmer climate."}],"publication":"npj Climate and Atmospheric Science","date_published":"2023-07-08T00:00:00Z","article_processing_charge":"Yes","doi":"10.1038/s41612-023-00411-5","acknowledgement":"This work was supported by National Research Foundation of Korea (NRF) grants funded by the Korean government (MSIT) (NRF-2018R1A5A1024958, RS-2023-00208000).

This view is not compatible with the organization and dynamical interactions across multiple scales of cloud systems in the tropics and progress in this research area was slow over decades despite the widely recognized major shortcomings. Novel ideas on how to represent key physical processes of moist convection‐large‐scale interaction to overcome the QEA have surged recently. The stochastic multicloud model (SMCM) CP in particular mimics the dynamical interactions of multiple cloud types that characterize organized tropical convection. Here, the SMCM is used to modify the Zhang‐McFarlane (ZM) CP by changing the way in which the bulk mass flux and bulk entrainment and detrainment rates are calculated. This is done by introducing a stochastic ensemble of plumes characterized by randomly varying detrainment level distributions based on the cloud area fraction of the SMCM. The SMCM is here extended to include shallow cumulus clouds resulting in a unified shallow‐deep CP. The new stochastic multicloud plume CP is validated against the control ZM scheme in the context of the single column Community Climate Model of the National Center for Atmospheric Research using data from both tropical ocean and midlatitude land convection. Some key features of the SMCM CP such as it capability to represent the tri‐modal nature of organized convection are emphasized."}],"doi":"10.1029/2022ms003391","date_published":"2023-11-01T00:00:00Z","article_processing_charge":"Yes","publication":"Journal of Advances in Modeling Earth Systems","acknowledgement":"The research of B.K. is supported in part by a Discovery Grant from the Natural Sciences and Engineering Research Council of Canada (RGPIN-04246-2020).

A significant contribution to the pre-monsoon TP heating comes from the sensible heat flux (SHF), which depend on the surface properties. A glaciated surface would have a different SHF compared to a non-glaciated surface. Therefore, the TP glaciers potentially can also impact the hydrological cycle in the Asian continent by impacting the ASM rainfall via its contribution to the total plateau heating. However, there is no assessment of this putative link available. Here, we attempt to qualitatively study the role of TP glaciers on ASM by analyzing the sensitivity of an atmospheric model to the absence of TP glaciers. We find that the absence of the glaciers is most felt in climatologically less snowy regions (which are mostly located at the south-central boundary of the TP during the pre-monsoon season), which leads to positive SHF anomalies. The resulting positive diabatic heating leads to rising air in the eastern TP and sinking air in the western TP. This altered circulation in turn leads to a positive SHF memory in the western TP, which persists until the end of the monsoon season. The impact of SHF anomalies on diabatic heating results in a large-scale subsidence over the ASM domain. The net result is a reduced seasonal ASM rainfall. Given the relentless warming and the vulnerability of glaciers to warming, this is another flag in the ASM variability and change that needs further attention.","lang":"eng"}],"intvolume":"       173","year":"2022","acknowledgement":"This research is funded by the IRCC research funding.","day":"30","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0165-0009","1573-1480"]},"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"access_level":"open_access","file_name":"2022_ClimateChange_Goswami.pdf","content_type":"application/pdf","date_updated":"2022-09-05T08:29:27Z","creator":"dernst","checksum":"38071d5c142bb76f8c8665dc374838a8","date_created":"2022-09-05T08:29:27Z","relation":"main_file","file_size":1350575,"file_id":"12021","success":1}],"publication_status":"published","has_accepted_license":"1","author":[{"last_name":"GOSWAMI","full_name":"GOSWAMI, BIDYUT B","first_name":"BIDYUT B","id":"3a4ac09c-6d61-11ec-bf66-884cde66b64b"},{"full_name":"An, Soon-Il","first_name":"Soon-Il","last_name":"An"},{"last_name":"Murtugudde","full_name":"Murtugudde, Raghu","first_name":"Raghu"}],"scopus_import":"1","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"12007","publisher":"Springer Nature","keyword":["Atmospheric Science","Global and Planetary Change"],"month":"08","type":"journal_article","title":"Role of the Tibetan plateau glaciers in the Asian summer monsoon","status":"public","quality_controlled":"1","article_type":"original","issue":"3-4","extern":"1","citation":{"ieee":"B.
