    International audienceInitiated by the French community, the HyMeX international project aims to improve our understanding of water cycle in the Mediterranean, its variability from meteorological event to seasonal and interannual scales, and its characteristics over a decade in a context of global change. The project is motivated by the role of mesoscale processes, coupled between the atmosphere, land and sea, on the climate systemand the onset of extreme hydro-meteorological events (precipitation and flash-flooding, strong winds and ocean convection, heat waves and droughts). The project also aims to assess the consequences of these extreme events on the social and economic vulnerability of this region and adaptability.D'initiative française, le projet international HyMeX a pour objectif d'amĂ©liorer la comprĂ©hension du cycle de l'eau en MĂ©diterranĂ©e, de sa variabilitĂ©, de l'Ă©chelle de l'Ă©vĂ©nement mĂ©tĂ©orologique aux Ă©chelles saisonniĂšres et interannuelles, et de ses caractĂ©ristiques sur une dĂ©cennie, dans un contexte de changement global. Le projet est motivĂ© par le rĂŽle dĂ©terminant des processus de mĂ©soĂ©chelle, couplĂ©s entre l'atmosphĂšre, la mer et la terre, sur la variabilitĂ© du systĂšme climatique et sur le dĂ©clenchement d'Ă©vĂ©nements hydromĂ©tĂ©orologiques extrĂȘmes (prĂ©cipitations et inondations, vents forts et convection ocĂ©anique, canicules et sĂ©cheresses). Le projet vise enfin Ă  Ă©valuer les consĂ©quences de ces Ă©vĂ©nements extrĂȘmes sur la vulnĂ©rabilitĂ© sociale et Ă©conomique de cette rĂ©gion et sa capacitĂ© d'adaptation
