Extreme rainfall events are frequently associated with regions of complex topography, where terrain-induced convergence and uplift enhance storm development. Understanding the interaction between surface relief and atmospheric dynamics is essential for improving severe weather forecasting and hazard mitigation. Storm “Daniel”, which affected Greece from 4–7 September 2023, produced extreme rainfall and widespread flooding in the Thessaly region—a landscape characterized by significant elevation gradients. This study investigates the spatial relationship between lightning activity and terrain elevation, aiming to assess whether deep convection was preferentially triggered over mountainous regions or followed specific orographic patterns. High-resolution elevation data (SRTM 1 Arc-Second Global DEM) were used to calculate the mean elevation around each lightning strike across four spatial scales (2 km, 5 km, 10 km, and 20 km). Statistical analysis, including correlation coefficients and third-degree polynomial regression, revealed a non-linear relationship, with a distinct peak in lightning frequency at mid-elevations (~200–400 m). These findings suggest that topographic features at local scales can significantly modulate convective initiation, likely due to a combination of mechanical uplift and favorable thermodynamic conditions. The study integrates geospatial techniques and statistical modeling to provide quantitative insights into how terrain influences the formation, location, and intensity of thunderstorms during high-impact weather events.

This study examines the impact of envelope renovation using Expanded Polystyrene (EPS) insulation and double glazing on reducing CO₂ emissions and energy consumption in low-income residential buildings in Mozambique’s tropical climate. Conducted in Maputo over 12 months (2023–2024), it targets urban households, addressing high energy use and emissions caused by inefficient building envelopes and limited access to sustainable technologies. The study uses DesignBuilder’s validated EnergyPlus engine to evaluate energy savings and financial viability within cultural and economic contexts. Results show a 42.16% reduction in energy consumption (from 5392.04 to 3118.69 kWh) and a 42.20% decrease in CO₂ emissions (from 3.27 × 10³ to 1.89 × 10³ kg) compared to conventional designs. With an 11.75% discount rate accounting for inflation and opportunity costs, the retrofit achieves a payback period of 6.9 years, confirming its financial viability. These findings offer policymakers, architects, and low-income communities a cost-effective retrofit model, advocating for policy integration of low-U-value materials to improve environmental and economic sustainability.

Climate change is an ongoing threat to heritage assets with compound climate extremes. Risk assessment and vulnerability approach show the consistent deterioration of ancient monuments. This study focuses on the open-air Greek theatre, a recognizable structure with cultural values and exposed to the climatic conditions. The methodology of this study is the collection of historical meteorological data from weather stations to assess the frequency and impacts of warm–wet, warm–dry, cold–wet, and cold–dry climate extremes on these structures. Climate historic documentation indicates an increasing frequency of these compound extremes, intensifying the structural degradation. Heritage management should include the mitigation–adaptation strategy based on the climate data and the assessment of climate change challenges for the protection of heritage and, in particular, of Greek open-air theatres.

An analysis was conducted using AERONET Inversion Data at Thessaloniki and Leipzig stations. Aerosol type plays a vital role in determining their ability to act as CCN or INP, as properties such as chemical composition, morphology, and particle size influence their hygroscopic and ice-nucleating behavior. The CALIPSO mission provides global aerosol classification with vertical resolution by using backscatter intensity and depolarization ratio measurements. Aerosol typing from CALIPSO overpasses within 100 km of each selected AERONET station was used. Only pure aerosol cases (dust, polluted continental, smoke) were selected. This study combines AERONET-derived microphysical properties with CALIPSO aerosol classification to estimate particle number concentrations relevant for CCN and INP formation. The aim is to derive improved conversion factors for each aerosol type, enabling their application in future CCN and INP concentration profiles. Full article

As cities grow, natural surfaces are replaced by heat-retaining materials, raising urban temperatures and intensifying heatwave impacts. The present study investigates the effectiveness of urban greening strategies, including green roofs, street vegetation and metropolitan parks, in enhancing climate resilience in Athens, a coastal Mediterranean city characterized by complex heatwave dynamics. The strategies were evaluated through simulations using the WRF model coupled with the BEP-BEM urban canopy model and a detailed land-cover map that is uses the 11 urban Local Climate Zones (LCZ) categories (CLIMPACT) tailored for Athens. Simulations focused on a significant heatwave event that affected the region in 2021 assessed the thermal impacts of the different greening scenarios. Results show that expanding green areas reduces peak temperatures and modifies local thermal circulations, highlighting the potential of greening in mitigating urban heat island effects.

Urban vegetation plays a key role in mitigating thermal stress in cities, particularly in Mediterranean climates increasingly affected by urban heat. This study evaluates the impact of vegetation on outdoor thermal comfort in Piazzetta San Michele Arcangelo, a square in Lecce (Southern Italy), using the ENVI-met microclimate model. Two scenarios were simulated: the current configuration and a hypothetical one without trees. Results show that vegetation reduces air temperature during the hottest hours (up to −0.52 °C on average) and improves thermal comfort, as indicated by the Universal Thermal Climate Index (UTCI), with reductions in “very strong heat stress” up to 43% at peak times. At night, tree canopies limit radiative cooling, leading to slight temperature increases. The findings confirm the crucial role of urban greening in enhancing outdoor thermal comfort and provide quantitative support for sustainable urban planning strategies in Mediterranean contexts.

Terminal Aerodrome Forecasts (TAFs) and long TAFs are issued by forecasters in the Hellenic National Meteorological Service for the upcoming 9 or 24 h respectively, for all airports to aid in flight planning. The most important predicted parameters are wind speed and direction, weather phenomena, and visibility. A verification procedure comparing TAFs to Meteorological Aerodrome Reports (METARs) can be helpful for improving the skills of forecasters. To this end, software was developed to read the raw format structure of TAFs and METARs and compare them. The wind speed and direction for each forecast hour are verified according to thresholds specified by the International Civil Aviation Organization (ICAO), and a summary is produced, showing correct, overestimated, and underestimated percentages. A weather phenomenon, such as rain (RA) or thunderstorm (TSRA), is usually given inside a probability time window in a TAF (e.g., PROB40 TEMPO RA). In such a case, the occurrence or absence of the phenomenon and its frequency inside the time window are considered when determining the forecaster’s skill (correct, false alarm, or miss), evaluated using categorical indices such as POD, ETS, and FAR over a number of TAFs. A similar procedure is carried out for visibility range intervals. In this study, verification was performed for a test period of January 2023 for 14 Greek airports. Results indicate generally good performance in predicting wind speed and direction, and also demonstrate the TAFs accuracy in detecting phenomena like rain, although with a notable tendency for false alarms. A systematic tendency to underestimate actual visibility, especially inside TEMPO statements is observed. Full article

ClimateHub, the National Collaboration Programme (NCP) in Greece aims at delivering innovative services to national authorities regulating the energy sector by developing climate-based tools and services building on the C3S experience. As a service provider, ClimateHub fills the knowledge and service gap on climate information at time scales exceeding the typical weather forecast. Through a co-design approach, ClimateHub has identified three applications where public authorities have virtually no access to climate-related impacts on the renewable energy sources (RES) sector at seasonal and decadal time scales, (a) energy demand, (b) solar power and (c) wind power. This study addresses the performance of ECWMF SEAS5 seasonal and the CMCC-CM2-SR5 decadal prediction systems over Greece, for near-surface temperature. Full article

In this contribution, three techniques related to modelling and remote sensing were tested to answer questions and satisfy requirements from air quality managers in the mining sector: (1) What are appropriate emission factors for blasting operations in copper mines? (2) How can we know the concentration of particulate matter in the next few hours in advance? (3) How can we generate a heat map of the particulate matter levels over the mine and nearby populations? These techniques were evaluated for one of the most relevant open pit mines in southern Europe, the Riotinto Mine, Huelva (Spain). The results obtained suggest that these techniques can efficiently improve the management of air quality in mining activities. Full article

On 31 March 2025, a severe thunderstorm system affected the Cyclades region, causing extensive flash floods on the islands of Paros and Mykonos and leading to significant material damage. This study investigates the meteorological characteristics of the event and focuses on the potential role of elevated sea surface temperatures (SSTs) in intensifying the storm’s severity. The analysis is centered on the broader Aegean region (geographic extent: 41.25° N, 21.83° E to 34.30° N, 28.51° E), utilizing ERA5 reanalysis data from ECMWF. These data provide high-resolution information on the atmospheric and ocean surface conditions during the event. The primary research objective is to explore how warmer SSTs may have contributed to enhanced moisture in the lower troposphere and increased energy availability for convective storm development. The theoretical background and a preliminary data exploration suggest that elevated SSTs likely favored increased evaporation, enhanced low-level moisture transport, and greater atmospheric instability, leading to the development of deep convective clouds. This, in turn, may have intensified precipitation rates and elevated the flood risk. This study aims to contribute to a better understanding of the mechanisms behind such extreme weather events, particularly in island environments, and to explore the sea’s potential catalytic role under a changing climate.

To analyze the climatic evolution of Greece, the ERA5-Land dataset, providing high spatial (~9 km) and temporal (daily) resolution, was utilized. Since the dataset comes from reanalysis (surface, satellite, and radiosonde measurements assimilated with the forecast model), it is ideal for assessing atmospheric variations. Input parameters were used to calculate the Johansson, Kerner, and Pinna climatic indices during the 1964–1993 and 1994–2023 periods. Along with the spatial distribution of the indices for each time interval, the spatial statistics related to the phytogeographical regions of Greece were also demonstrated. The results indicate a clear shift in the climate’s characterization by more “Continental” and more “Moderate Dry” classes, mostly in inland parts of the country. Outcomes involving the mapping material along with spatial statistics data may shed light on the spatial and temporal changes in the climate over the Greek peninsula. Full article

Our study focuses on investigating the present-day influence of wildfires on the global atmosphere. To achieve this, we utilized four observational biomass burning (BB) emissions datasets for present-day simulations employing the TM5 Chemical Transport Model (CTM). To assess how different emissions estimates influence the model’s ability to simulate the atmosphere, we compared the following datasets over the period 2003–2015: GFED4s, GFASv1.2, FEERv1.0-G1.2 and QFEDv2.6r1. Our study aims to investigate the role of wildfires in affecting important trace gases and aerosols. Their impact on atmospheric composition and their interactions with solar radiation affect the radiative balance at the Earth’s surface and, consequently, temperature trends in the troposphere.

Air pollution imposes significant economic burdens due to its adverse health effects. This study estimates the economic cost of premature mortality from PM₁₀ and ground-level O₃ exposure in the Greater Athens Area (2001–2019), using the value of statistical life and willingness-to-pay methods. Despite low PM₁₀ levels in 2011, rising O₃ concentrations from 2015–2019 correlated with increased cardiorespiratory mortality costs. The average cost reached €1253 million per 100,000 people. Results suggest air pollution mortality costs follow Gross Domestic Product (GDP) trends, underscoring the economic and public health value of improving air quality. Full article

Here, we assess the projected changes in photovoltaic power generation potential (PVpot) in Greece for the 21st century. Our analysis is based on an ensemble of high-resolution Regional Climate Model (RCM) simulations from the EURO-CORDEX initiative following three different Representative Concentration Pathways (RCPs), namely, RCP2.6 (strong mitigation), RCP4.5 (moderate mitigation), and RCP8.5 (no further mitigation). The spatial patterns of the PVpot changes in the near future (2021–2050) and at the end of the century (2071–2100) relative to the 1971–2000 baseline period are presented along with the corresponding statistical robustness. In addition, we analyze time series of the projected PVpot changes. Finally, we isolate the effects of specific climatic variables on the projected PVpot changes and discuss the importance of PV energy production in Greece. Full article
