{"oa":1,"abstract":[{"lang":"eng","text":"We investigate how mesoscale circulations associated with convective aggregation can modulate the sensitivity of the hydrologic cycle to warming. We quantify changes in the full distribution of rain across radiative‐convective equilibrium states in a cloud‐resolving model. For a given SST, the shift in mean rainfall between disorganized and organized states is associated with a shift in atmospheric radiative cooling, and is roughly analogous to the effect of a 4K SST increase. With rising temperatures, the increase in mean rain rate is insensitive to the presence of organization, while extremes can intensify faster in the aggregated state, leading to a faster amplification in the sporadic nature of rain. When convection aggregates, heavy rain is enhanced by 20‐30% and nonlinear behaviors are observed as a function of SST and strength of aggregation feedbacks. First, radiative‐ and surface‐flux aggregation feedbacks have multiplicative effects on extremes, illustrating a non‐trivial sensitivity to the degree of organization. Second, alternating Clausius‐Clapeyron and super‐Clausius‐Clapeyron regimes in extreme rainfall are found as a function of SST, corresponding to varying thermodynamic and dynamic contributions, and a large sensitivity to precipitation efficiency variations in some SST ranges.\r\nThe potential for mesoscale circulations in amplifying the hydrologic cycle is established. However these nonlinear distortions question the quantitative relevance of idealized self‐aggregation. This calls for a deeper investigation of relationships which capture the coupling between global energetics, aggregation feedbacks and local convection, and for systematic tests of their sensitivity to domain configurations, surface boundary conditions, microphysics and turbulence schemes."}],"date_published":"2021-02-01T00:00:00Z","oa_version":"Published Version","tmp":{"image":"/images/cc_by_nc.png","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","short":"CC BY-NC (4.0)","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)"},"type":"journal_article","file":[{"date_created":"2021-08-11T12:23:01Z","file_size":1947936,"date_updated":"2021-08-11T12:23:01Z","creator":"kschuh","checksum":"591ce69b7a36f24346d2061ac712f0f4","relation":"main_file","file_name":"2021_JAMES_Fildier.pdf","content_type":"application/pdf","file_id":"9881","access_level":"open_access","success":1}],"article_number":"e2020MS002256","article_type":"original","publisher":"American Geophysical Union","issue":"2","day":"01","intvolume":"        13","file_date_updated":"2021-08-11T12:23:01Z","publication_identifier":{"issn":["1942-2466","1942-2466"]},"date_created":"2021-02-15T15:10:01Z","language":[{"iso":"eng"}],"article_processing_charge":"No","title":"Distortions of the rain distribution with warming, with and without self‐aggregation","status":"public","license":"https://creativecommons.org/licenses/by-nc/4.0/","publication_status":"published","volume":13,"extern":"1","ddc":["550"],"scopus_import":"1","keyword":["Global and Planetary Change","General Earth and Planetary Sciences","Environmental Chemistry"],"publication":"Journal of Advances in Modeling Earth Systems","month":"02","citation":{"mla":"Fildier, Benjamin, et al. “Distortions of the Rain Distribution with Warming, with and without Self‐aggregation.” <i>Journal of Advances in Modeling Earth Systems</i>, vol. 13, no. 2, e2020MS002256, American Geophysical Union, 2021, doi:<a href=\"https://doi.org/10.1029/2020ms002256\">10.1029/2020ms002256</a>.","ista":"Fildier B, Collins WD, Muller CJ. 2021.
