Fewer clouds in the Mediterranean: consistency of observations and climate simulations Sánchez Lorenzo, Arturo Enríquez Alonso, Aarón Calbó Angrill, Josep González Gutiérrez, Josep Abel Wild, Martin Folini, Doris Norris, Joel R. Vicente Serrano, Sergio Martín Ministerio de Ciencia e Innovación (Espanya) Ministerio de Economía y Competitividad (Espanya) Climatologia -- Simulació, Mètodes de Climatology -- Simulation methods Núvols Clouds Clouds play a major role in the climate system, but large uncertainties remain about their decadal variations. Here we report a widespread decrease in cloud cover since the 1970 s over the Mediterranean region, in particular during the 1970 s–1980 s, especially in the central and eastern areas and during springtime. Confidence in these findings is high due to the good agreement between the interannual variations of cloud cover provided by surface observations and several satellite-derived and reanalysis products, although some discrepancies exist in their trends. Climate model simulations of the historical experiment from the Coupled Model Intercomparison Project Phase 5 (CMIP5) also exhibit a decrease in cloud cover over the Mediterranean since the 1970 s, in agreement with surface observations, although the rate of decrease is slightly lower. The observed northward expansion of the Hadley cell is discussed as a possible cause of detected trends Several authors are involved within the projects CGL2010-18546, CGL2014-55976-R, and CGL2014-52135-C03-01 funded by the Spanish Ministry of Economy and Competitiveness 2017-02-02 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://hdl.handle.net/10256/13871 http://hdl.handle.net/10256/13871 eng info:eu-repo/semantics/altIdentifier/doi/10.1038/srep41475 info:eu-repo/semantics/altIdentifier/issn/2045-2322 info:eu-repo/grantAgreement/MICINN//CGL2010-18546/ES/LAS NUBES Y SUS EFECTOS SOBRE LA RADIACION: DEL ESTUDIO DE SITUACIONES A ESCALA LOCAL AL ANALISIS CLIMATOLOGICO DE ALCANCE GLOBAL.
