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 trendsSeveral 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 Attribution 3.0 Spain http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess Climatologia -- Simulació, Mètodes de Climatology -- Simulation methods Núvols Clouds Fewer clouds in the Mediterranean: consistency of observations and climate simulations info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
