To test this hypothesis, we explore six years of distributed meteorological data on a small Swiss glacier in the period 2001–2022. Large glacier fragmentation has occurred since 2001 (−35% area change up to 2022) coinciding with notable frontal retreat, an observed switch from down‐glacier katabatic to up‐glacier valley winds and an increased sensitivity (ratio) of on‐glacier to off‐glacier temperature. As the glacier ceases to develop density‐driven katabatic winds, sensible heat fluxes on the glacier are increasingly determined by the conditions occurring outside the boundary layer of the glacier, sealing the glacier's demise as the climate continues to warm and experience an increased frequency of extreme summers.","lang":"eng"}],"volume":50,"article_number":"e2023GL103043","article_type":"original","issue":"11","intvolume":"        50"},{"publisher":"Wiley","has_accepted_license":"1","file_date_updated":"2022-01-24T12:14:41Z","publication":"Geophysical Research Letters","month":"01","file":[{"access_level":"open_access","creator":"cchlebak","date_updated":"2022-01-24T12:14:41Z","file_id":"10662","file_name":"2022_GeophysResearchLet_Abramian.pdf","date_created":"2022-01-24T12:14:41Z","file_size":1117408,"checksum":"08f88b57b8e409b42e382452cd5f297b","content_type":"application/pdf","relation":"main_file","success":1}],"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), and from the PhD fellowship of Ecole Normale Supérieure de Paris-Saclay.

Also, as the magnitude of the shear increases beyond a critical shear, squall lines tend to orient themselves. The existing literature suggests that this orientation reduces incoming wind shear to the squall line, and maintains equilibrium between wind shear and cold pool spreading. Although this theory is widely accepted, very few quantitative studies have been conducted on supercritical regime especially. Here, we test this hypothesis with tropical squall lines obtained by imposing a vertical wind shear in cloud resolving simulations in radiative convective equilibrium. In the sub-critical regime, squall lines are perpendicular to the shear. In the super-critical regime, their orientation maintain the equilibrium, supporting existing theories. We also find that as shear increases, cold pools become more intense. However, this intensification has little impact on squall line orientation.","lang":"eng"}],"title":"Shear-convection interactions and orientation of tropical squall lines","scopus_import":"1","department":[{"_id":"CaMu"}],"language":[{"iso":"eng"}],"date_created":"2022-01-23T23:01:27Z"},{"intvolume":"        49","article_number":"e2022GL100624","article_type":"letter_note","issue":"24","tmp":{"image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"abstract":[{"lang":"eng","text":"The sensitivity of coarse-grained daily extreme precipitation to sea surface temperature is analyzed using satellite precipitation estimates over the 300–302.5 K range. A theoretical scaling is proposed, linking changes in coarse-grained precipitation to changes in fine-scale hourly precipitation area fraction and changes in conditional fine-scale precipitation rates. The analysis reveals that the extreme coarse-grained precipitation scaling with temperature (∼7%/K) is dominated by the fine-scale precipitating fraction scaling (∼6.5%/K) when using a 3 mm/h fine-scale threshold to delineate the precipitating fraction. These results are shown to be robust to the selection of the precipitation product and to the percentile used to characterize the extreme. This new coarse-grained scaling is further related to the well-known scaling for fine-scale precipitation extremes, and suggests a compensation between thermodynamic and dynamic contributions or that both contributions are small with respect to that of fractional coverage. These results suggest that processes responsible for the changes in fractional coverage are to be accounted for to assess the sensitivity of coarse-grained extreme daily precipitation to surface temperature."}],"volume":49,"title":"Precipitating fraction, not intensity, explains extreme coarse-grained precipitation Clausius-Clapeyron scaling with sea surface temperature over tropical oceans","scopus_import":"1","language":[{"iso":"eng"}],"date_created":"2023-01-08T23:00:53Z","department":[{"_id":"CaMu"}],"type":"journal_article","day":"28","citation":{"ieee":"R.

However, studies have found that the surface of these debris-covered glaciers is actually lowering as fast as glaciers without debris. Water ponded on the surface of the glaciers may be partially responsible, as water can absorb atmospheric energy very efficiently. However, the overall effect of these ponds has not been thoroughly assessed yet. We study a valley in Nepal for which we have extensive weather measurements, and we use a numerical model to calculate the energy absorbed by ponds on the surface of the glaciers over 6 months. As we have not observed each individual pond thoroughly, we run the model 5,000 times with different setups. We find that ponds are extremely important for glacier melt and absorb energy 14 times as quickly as the debris-covered ice. Although the ponds account for 1% of the glacier area covered by rocks, and only 0.3% of the total glacier area, they absorb enough energy to account for one eighth of the whole valley's ice loss."}],"article_type":"letter_note","issue":"19","intvolume":"        45","extern":"1","month":"10","publication":"Geophysical Research Letters","publisher":"American Geophysical Union","_id":"12604","publication_status":"published","date_updated":"2023-02-28T11:46:48Z","publication_identifier":{"issn":["0094-8276"],"eissn":["1944-8007"]},"year":"2018","status":"public","date_published":"2018-10-18T00:00:00Z","page":"10464-10473","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","author":[{"full_name":"Miles, Evan S.","first_name":"Evan S.","last_name":"Miles"},{"first_name":"Ian","full_name":"Willis, Ian","last_name":"Willis"},{"full_name":"Buri, Pascal","first_name":"Pascal","last_name":"Buri"},{"last_name":"Steiner","first_name":"Jakob F.","full_name":"Steiner, Jakob F."},{"full_name":"Arnold, Neil S.","first_name":"Neil S.","last_name":"Arnold"},{"first_name":"Francesca","full_name":"Pellicciotti, Francesca","last_name":"Pellicciotti","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70"}],"keyword":["General Earth and Planetary Sciences","Geophysics"],"oa":1},{"main_file_link":[{"url":"https://doi.org/10.1029/2009GL039667","open_access":"1"}],"citation":{"mla":"Muller, Caroline J., et al. “A Model for the Relationship between Tropical Precipitation and Column Water Vapor.” <i>Geophysical Research Letters</i>, vol. 36, no. 16, L16804, American Geophysical Union, 2009, doi:<a href=\"https://doi.org/10.1029/2009gl039667\">10.1029/2009gl039667</a>.","ista":"Muller CJ, Back LE, O’Gorman PA, Emanuel KA. 2009.

We show that the observed relationship in the tropics between column‐integrated water vapor, precipitation, and its variance can be qualitatively reproduced by a simple and physically motivated two‐layer model. It has previously been argued that features of this relationship could be explained by analogy with the theory of continuous phase transitions. Instead, our model explicitly assumes that the onset of precipitation is governed by a stability threshold involving boundary‐layer water vapor. This allows us to explain the precipitation‐humidity relationship over a broader range of water vapor values, and may explain the observed temperature dependence of the relationship."}],"volume":36,"title":"A model for the relationship between tropical precipitation and column water vapor","language":[{"iso":"eng"}],"date_created":"2021-02-15T14:41:28Z","publisher":"American Geophysical Union","publication":"Geophysical Research Letters","month":"08","oa":1,"author":[{"last_name":"Muller","id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b","first_name":"Caroline J","full_name":"Muller, Caroline J","orcid":"0000-0001-5836-5350"},{"last_name":"Back","full_name":"Back, Larissa E.","first_name":"Larissa E."},{"last_name":"O'Gorman","first_name":"Paul A.","full_name":"O'Gorman, Paul A."},{"full_name":"Emanuel, Kerry A.","first_name":"Kerry A.","last_name":"Emanuel"}],"keyword":["General Earth and Planetary Sciences","Geophysics"],"article_processing_charge":"No","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","status":"public","date_published":"2009-08-25T00:00:00Z","year":"2009","publication_identifier":{"issn":["0094-8276"]},"date_updated":"2022-01-24T13:50:15Z","publication_status":"published","_id":"9148"}]
