Such interactions have been reported in both numerical and observational studies, mainly showing that subsidence from the stratosphere into the eye of an intensifying storm leads to a high-level warm core. However, the effect of this upper-level warming on the intensity of the TCs is not yet well understood. In this study, we show that subsiding air from the stratosphere beyond subsidence in the eye is the reason for the upper-level warming in idealized simulations. We further show that it is possible to quantify the effects of the upper-level warming on the potential intensity of the TC. Finally, we conclude that overshooting convection into the stratosphere causes the observed subsidence, as both become more pronounced with increasing sea-surface temperatures (SST).","lang":"eng"}],"oa_version":"Published Version","dataavailabilitystatement":"The post‐processed simulation data and the analysis scripts are available on Figshare https://doi.org/10.6084/m9.figshare.30933764 (Charinti et al., 2025).","article_type":"original","ddc":["550"],"department":[{"_id":"CaMu"},{"_id":"GradSch"}],"article_processing_charge":"Yes","type":"journal_article","OA_type":"gold","acknowledgement":"GAC and CM 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).
