Abstract Extreme precipitation events lead to dramatic impacts on society and the situation will worsen under climate change. Decision-makers need reliable estimates of future changes as a basis for effective adaptation strategies, but projections at local scale from regional models (RCMs) are highly uncertain. Here we exploit km-scale convection-permitting multi-model (CPM) ensemble, generated within FPS Convection project, provide new understanding in extremes related uncertainties over...
Abstract. In the recent past, an increase in computation resources led to development of regional climate models with increasing domains and resolutions, spanning larger temporal periods. A good example is World Climate Research Program – Coordinated Regional Downscaling Experiment for European domain (EURO-CORDEX). This set encompasses entire continent a 130-year common period until end 21st century, while having 12 km horizontal resolution. Such simulations are computationally demanding,...
Abstract. Over the years, higher-resolution regional climate model simulations have emerged owing to large increase in computational resources. The 12 km resolution from Coordinated Regional Climate Downscaling Experiment for European domain (EURO-CORDEX) is a reference, which includes larger multi-model ensemble at continental scale while spanning least 130-year period. These are computationally demanding but do not always reveal added value. In this study, recently developed regular...

Droughts are a long-term weather-driven extreme event which occurs worldwide with great socio-economic impacts, namely in the Mediterranean and Iberian regions. In changing climate rising temperatures, events, such as droughts, expected to increase frequency intensity, particularly climates. this context, assessment of evolution drought terms its duration intensity Peninsula (IP) is paramount, it affects several activities. The use new high-resolution gridded datasets allows for...
Abstract The increase in computational resources has enabled the emergence of multi-model ensembles convection-permitting regional climate model (CPRCM) simulations at very high horizontal resolutions.

This first-of-its-kind ensemble, forced by ERA-Interim reanalysis, can be considered benchmark dataset. study uses recently proposed...
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...
Abstract The African continent faces several challenges and threats: high vulnerability to climate change, the fastest population increase, lowest degree of electrification need for an energy transition towards renewable energies. Solar constitutes a viable option addressing these issues. In changing efficient implementation solar capacity should rely on comprehensive information about resource. Here, newest highest resolution regional simulation results are used project future photovoltaic...
