Earlier reports indicated some specific isolated regions exhibiting a paradoxical increase of extreme rainfall in spite decrease the totals. Here, we conduct coherent study full‐scale daily categories over relatively large subtropical region‐ Mediterranean‐ order to assess whether this behavior is real and its extent. We show that torrential Italy exceeding 128 mm/d has increased percentage‐wise by factor 4 during 1951–1995 with strong peaks El‐Nino years. In Spain, at both tails...

The Mediterranean countries are experiencing important challenges related to the water cycle, including shortages and floods, extreme winds, ice/snow storms, that impact critically socioeconomic vitality in area (causing damage property, threatening lives, affecting energy transportation sectors, etc.). There gaps our understanding of cycle its dynamics include variability Sea budget feedback on continental precipitation through air–sea interactions, aquifer recharge, river discharge, soil...

Abstract. A large number of intense cyclones occur every year in the Mediterranean basin, one climate change hotspots. Producing a broad range severe socio-economic and environmental impacts such densely populated region, call for coordinated interdisciplinary research efforts. This article aims at supporting these efforts by reviewing status knowledge field cyclones. First, we focus on climatology cyclone tracks, their relationship to large-scale atmospheric circulation future trends....

Abstract After extensive efforts over the course of a decade, convective-scale weather forecasts with horizontal grid spacings 1–5 km are now operational at national services around world, accompanied by ensemble prediction systems (EPSs). However, though already operational, capacity for this scale is still to be fully exploited overcoming fundamental difficulty in prediction: three-dimensional and turbulent nature atmosphere. The totally different from that synoptic (10 3 km), slowly...

Abstract Projections of climate change effects for the System Platja de Palma (SPdP) are derived using a novel statistical technique. Socioeconomic activities developed in this settlement very closely linked to its climate. Any planning socioeconomic opportunities mid- and long term must take into account possible change. To aim, daily observed series minimum maximum temperatures, precipitation, relative humidity, cloud cover, wind speed have been analyzed. For projections, data generated by...

Abstract The nature of the seasonality precipitation in eastern and southern coastal Spain (including both Mediterranean far southwestern Atlantic provinces) is examined using monthly values available for 410 sites period 1964–1993. Important contrasts are illustrated between (Mediterranean) (Atlantic) areas. In east, more subdued due to incursions fronts from north at all times year. south, months July August almost completely dry, but October–February wet active frontal systems. central...

Abstract A small, quasi‐tropical cyclone occurred on 12 September 1996 over the western Mediterranean. Intense convective activity region during this period also produced a tornado outbreak in Balearic Islands and torrential precipitation eastern mainland Spain. Mesoscale model runs properly simulate formation show convection heavy following trajectory its eastward progression. sensitivity study examining upper‐level dynamic forcing, latent‐ sensible‐heat fluxes from sea, orography is...

Abstract Climatic shifts may increase the extinction risk of populations, especially when they are already suffering from other anthropogenic impacts. Our ability to predict consequences climate change on endangered species is limited by our scarce knowledge effects variability population dynamics most organisms and uncertainty projections, which depend strongly region earth being considered.

Abstract On 12 October 2007, several flash floods affected the Valencia region, eastern Spain, with devastating impacts in terms of human, social, and economic losses. An enhanced modeling forecasting these extremes, which can provide a tangible basis for flood early warning procedures mitigation measures over Mediterranean, is one fundamental motivations international Hydrological Cycle Mediterranean Experiment (HyMeX) program.

Abstract. An extraordinary convective rainfall event, unforeseen by most numerical weather prediction models, generated a devastating flash flood (305 m3 s−1) in the town of Sant Llorenç des Cardassar, Mallorca, on 9 October 2018. Four people died inside this village, while casualties were up to 13 over entire affected area. This extreme event has been reconstructed implementing an integrated modelling approach Ses Planes catchment (23.4 km2), based three components: (i) generation...

Abstract. One of the multiple approaches currently explored to mitigate effects hydro-meteorological hazardous events aims at improving numerical weather forecasts. Under an ever increasing societal demand for cost cuts and more precise forecasts, targeted observations are receiving great attention within operational community. The MEDEX project (http://medex.inm.uib.es) is aimed forecasts high impact (HIW) in Mediterranean and, particular, proposes creation a climatology sensitivities such...

High-impact weather events over sparse data regions with complex orography, such as the Mediterranean region, remain a challenge for numerical prediction. This study evaluates, first time, ability of multiscale ensemble-based assimilation system to reproduce heavy precipitation episode that occurred during Special Observation Period (SOP1) Hydrological cycle in Experiment (HyMeX). During Intense (IOP13) from 14 15 October 2012, convective maritime activity associated an advancing cold front...
