. 2019 ; Tuel and Eltahir 2020 ) and the land-sea warming contrast ( Brogli et al. 2019 ; Tuel and Eltahir 2020 ). Tuel and Eltahir (2020 , hereinafter TE20) explained the development of the anomalous Mediterranean high as the combined response to shifts in the large-scale structure of the mean wintertime circulation and to surface temperature trends. A robust eastward shift in winter stationary waves ( Simpson et al. 2016 ) pushes the Atlantic Ocean subtropical high closer to the Mediterranean

that dynamical perturbations driven by Arctic sea ice decrease could also impact the Mediterranean area, in particular changing the intensity and the probability of extreme climate events. An increasing trend in the occurrence of extreme winter precipitation events (from heavy to torrential) in Spain and Italy has been identified by Toreti et al. (2010) . Between January 1950 and October 2009, 395 severe flood and storm events were also reported by EM-DAT (2009) for 19 Mediterranean countries

Adriatic Sea). The mean flow moisture divergence arises both from a divergent mean flow over the eastern Mediterranean region, much of North Africa, and the Iberian Peninsula and general dry advection over the region ( Fig. 1 ). In contrast, the transient eddy moisture flux ( Fig. 1h ) is convergent over all the land areas surrounding the Mediterranean Sea, with the exception of the Nile delta and the coastal area of Libya south of Benghazi, and over Northern European land areas as well. Hence, it is

1. Background and aims a. Ligurian Sea: Meteorology and oceanography The Ligurian Sea, in the northwestern Mediterranean, comprises the ocean area east of the Gulf of Lion and north of the island of Corsica ( Fig. 1 ). The weather over the Ligurian Sea is strongly influenced by the surrounding landmasses, and in particular the mountain ranges of the Alps, Massif Central, and the Pyrenees. Cyclogenesis occurs in the lee of the Alps year-round, with a strong seasonal cycle: it is most common in

THE PROBLEM OF THE MEDITERRANEAN REGION CLIMATE SIMULATIONS. A multimodel system for the Mediterranean region improves simulation of physical processes involved in the complex, intricate interaction of land, air, and sea. The climate of the Mediterranean region, defined here as the area including the Mediterranean Sea and the surrounding areas, is determined by the interaction between midlatitude and subtropical circulation regimes with the complex morphology (mountain chains and land–sea

1. Introduction The sea level difference between the Atlantic Ocean and the Mediterranean Sea has been attributed mostly to the following: tides (e.g., Brandt et al. 2004 ), atmospheric pressure fluctuations (e.g., Tsimplis and Josey 2001 ), steric contributions (e.g., Cazenave et al. 2002 ), and geostrophic or hydraulic controls within the Strait of Gibraltar (e.g., Ross and Garrett 2000 ). Some studies ( Fukumori et al. 2007 ; García-Lafuente et al. 2002a , b ; Garrett 1983 ), however

1. Introduction The Greenland Sea, the Labrador Sea, and the Mediterranean Sea are the few particular seas exposed to very strong atmospheric conditions in winter in which localized open-ocean regions characterized by weak stratification allow vertical mixing to reach very great depths. The main mechanism involved in the process is so-called deep convection. This phenomenon occurs in particular in the Gulf of Lion (northwestern Mediterranean Sea) and has been studied thoroughly since the 1970s

1. Introduction Unique morphological characteristics make the Mediterranean basin prone to natural hazards related to the water cycle ( Flaounas et al. 2019 ), in particular during autumn when the air–sea thermal contrast becomes remarkable. Steep slopes in the vicinity of coastal areas, and the Mediterranean Sea itself, which acts as a large source of moisture and heat, instigate rapid uplift of moist, unstable air, responsible for triggering condensation and convective instability processes

; Jansa et al. 2014 ) and the Hydrological Cycle in the Mediterranean Experiment (HyMeX, Drobinski et al. 2014 ). Such events are characterized by a pronounced large-scale trough, which slowly evolves eastward over the western Mediterranean Sea basin ( Grazzini 2007 ). However, the Vaia event turned out to be exceptional, not only in terms of wind and accumulated precipitation (up to 850 mm in three days, with a return period exceeding 100 years; ARPAV 2018 ), but also of integrated water vapor (IWV

Drifter designs CODE drifters were developed by Davis (1985) in the early 1980s to measure the currents in the first meter under the sea surface. They were mostly used in coastal areas and in marginal seas such as the Gulf of Mexico ( Ohlmann et al. 2001 ; Ohlmann and Niiler 2005 ; LaCasce and Ohlmann 2003 ) and the Mediterranean Sea ( Poulain 1999 , 2001 ; Poulain and
