Climate change constitutes a major threat for all the Mediterranean countries due to combination of large precipitation reductions and temperature increases higher frequency climate extremes, especially driving water scarcity derived multi-sectoral impacts. Portugal, as most countries, already endures larger frequencies droughts deficits in soil moisture storage. In current study, future projections are examined using multi-model EURO-CORDEX regional ensemble, agreement with three emission...
Climate indices are developed to determine climate impacts on different socioeconomic sectors, providing a comprehensive communication of complex information arising from change assessments. These may be used by decision-makers properly and timely implement adaptation measures in sectors human activity, such as agriculture crop selection, forest, coastal management, among others. Here, we present analysis estimated for Portugal, known hotspot. A multi-variable 13-member ensemble EURO-CORDEX...
Climate projections are a powerful tool that can help decision makers to timely prepare adaptation policies, which may then be efficiently implemented. In this study, comprehensive analysis of how climate change affect Portugal (located in hotspot) is conducted, providing the foundations first National Roadmap for Adaptation 2100. A multi-variable ensemble was built and tested, being baseline assessing future three different emission scenarios (RCP2.6, RCP4.5, RCP8.5) throughout 21st...
Abstract. Deep learning (DL) methods have recently garnered attention from the climate change community for being an innovative approach to downscaling variables Earth system and global models (ESGCMs) with horizontal resolutions still too coarse represent regional- local-scale phenomena. In context of Coupled Model Intercomparison Project phase 6 (CMIP6), ESGCM simulations were conducted Sixth Assessment Report (AR6) Intergovernmental Panel on Climate Change (IPCC) at ranging 0.70 3.75∘....
Abstract A global quantitative characterization of offshore wind power density is presented over the economic exclusive zones (EEZs), at annual and seasonal scales, based on recently released ECMWF ERA-5 reanalysis. Compared to its predecessors, features increased spatial temporal resolutions, along with improved model parameterizations data assimilation methodologies. Consequently, present study represents an updated benchmark resources oceans. Further robustness this argument provided by...
Abstract As a result of warming and precipitation deficits, the increasing shortage water resources, droughts have become one main drivers desertification, land degradation food insecurity with direct impacts on ecosystems society, especially in fragile communities. Over Iberian Peninsula, known climate change hotspot, occurrence varies intensity severity, being its assessment under present future conditions an important tool for adaptation measures. Here, first time, we comprehensive...
Cities are considered local "hotspots" of climate change, therefore, the improvement urban present description as well future projections is paramount for designing adaptation and mitigation strategies. Physically-based numerical models often have coarse resolutions do not parametrisations to adequately represent physical processes at scale. This article presents an innovative application XGBoost (a machine learning approach) alternative explore improve Madrid. XGBoost's ability reproduce...
The Iberian Peninsula (IP) is anticipated to undergo future shifts in precipitation patterns and an increased occurrence of hot dry extreme (HDE) weather events, including droughts heatwaves. Such events pose substantial risks the region’s population ecosystems, particularly amidst evolving demographic dynamics marked by overall decrease contrasting growth urban areas. This study evaluates exposure HDEs IP, comparing projected conditions for late 21st century with historical period...
In recent years, an increase in the frequency of occurrence heatwaves and number hot days Europe is undeniable. Hence, there increased need to understand feedback mechanisms relevant their development. Due localised impact although they modify local land surface properties that control land-atmosphere mass, energy, momentum exchanges, influence use/land cover changes (LUC) at regional scales still needs be better represented coordinated downscaling experiments. The Flagship Pilot Study LUCAS...
Droughts are among the most impactful and complex climatic phenomena, widely recognised as pervasive natural hazards posing serious challenges to ecosystems societies. Assessing droughts is challenging due difficulties in accurately determining their spatial temporal dimensions. This study introduces a novel daily drought index, Generalized Drought Index (GDI), calculated using Iberian Gridded Dataset (1971–2015) with precipitation minus potential evapotranspiration data. The...
The increasing frequency and intensity of extreme environmental climatic stressors, such as heatwaves, droughts, wildfires, air pollution episodes, highlight the urgency understanding their interconnected nature. Traditionally studied in isolation, these stressors often interact complex ways, amplifying individual cumulative impacts on ecosystems, economies, public health. This study explores global occurrence compound events involving poor quality, identifying key drivers, spatial...
Cities are considered local “hotspots” of climate change. Urban areas concentrate a large fraction global population, wealth, and emissions, exposing their inhabitants to change impacts. Therefore, the improvement urban present description future projections paramount for designing adaptation mitigation strategies. Global Climate Models state-of-the-art tools projecting climate. However, most simulations have coarse resolutions do not physical parametrisations adequately...
Abstract Global reanalyses are powerful tools to study the recent climate. They built by combining forecast models with observations through data assimilation, which provide complete spatial and temporal information of observable unobservable parameters. The constitute very valuable three-dimensional atmosphere, make it possible investigate a panoply atmospheric processes, such as coastal low-level jets (CLLJs). In present study, three global reanalyses, European Centre for Medium-Range...
Most state-of-the-art climate simulation ensembles misrepresent the effects of urbanization on local due to computational restrictions, posing a major limitation for urban projections. We circumvent this shortcoming by employing SURFEX land-surface model coupled TEB (Town Energy Balance) canopy model, forced EURO-CORDEX regional simulations. demonstrate added-value CORDEX-SURFEX-TEB compared in reproducing Lisbon's temperature observations, halving bias and improving PDF matching ~5%....
A sharp temperature contrast, observed mostly in summer, between high temperatures over land and lower the ocean typical summer synoptic scale configuration (high-pressure system thermal low inland) are responsible for development of a coastal low-level jet (CLLJ). The horizontal pressure gradient induces, through geostrophic adjustment, strong alongshore flow, which is also influenced by local orography high-pressure subsidence maritime boundary layer. In this study, EURO-CORDEX hindcast...
ABSTRACT The spatial variability and the climatic characteristics of coastal low‐level jet along west coast Iberian Peninsula are presented in this study, based on a 9‐km resolution downscaling data set, produced using weather research forecasting model, forced by ERA‐Interim reanalysis. Iberia is divided into two (north south) subareas, where (IPCJ) studied separately, compared to whole western Iberia. It shown that while IPCJ occurrences more frequent southern area, during summer...
Offshore wind is one of the most important sources renewable energy. Therefore, it crucial to assess how this resource will evolve over 21st century in context a changing climate. The North African Coastal Low-Level Jet (CLLJ) region, which encompasses offshore areas from Northwest Morocco Senegal, has an enormous wind-harvesting potential, as provides strong, persistent alongshore flow. In current study, present climate energy potential featured for two heights (100 and 250 m). More...

Abstract. Cities concentrate people, wealth, emissions, and infrastructure, thus representing a challenge an opportunity for climate change mitigation adaptation. This urgently demands accurate urban projections to help organizations individuals make climate-smart decisions. However, most of the large ensembles global regional model simulations do not include sophisticated parameterizations (e.g., EURO-CORDEX; CMIP5/6). Here, we explore this shortcoming in ERA5 (the latest generation...
