Sci. Res., 22, 165–176, https://doi.org/10.5194/asr-22-165-2026, 2026<br> On 6 July 2023, a severe hailstorm hit Vitoria-Gasteiz, caused by a supercell. Active cells moved southwest to northeast, with some shifting west-east. The storm, with radar reflectivities up to 65 dBz, brought intense showers and hail up to 5 cm in diameter. It caused injuries, vehicle damage and urban flooding. This study analyzes the storm’s conditions and surface effects using different data. 2026-05-13T18:47:06+02:00 https://doi.org/10.5194/asr-22-149-2026 <b>The regional reanalysis COSMO-R6G2 as a successor to COSMO-REA6: evaluation for renewable energy applications</b><br> Franziska Bär, Michael Borsche, Frank Kaspar, Thomas Spangehl, Dehong Yuan, David Geiger, and Lukas Pauscher<br> Adv. Sci. Res., 22, 149–164, https://doi.org/10.5194/asr-22-149-2026, 2026<br> COSMO-REA6 is widely used in energy applications but has known deficits. Its successor, COSMO-R6G2, is evaluated for Germany, focusing on Global Horizontal Irradiance (GHI) as well as wind speed. It shows slightly lower GHI and good wind quality in flat areas, but underestimates night-time wind in mountains. Overall, it is a useful successor, though users should consider remaining limitations. 2026-05-11T18:47:06+02:00 https://doi.org/10.5194/asr-22-131-2026 <b>Assessing the performance of reanalysis and meso-scale model datasets for onshore wind power modelling in Germany</b><br> David Geiger, Christoph Zink, Franziska Bär, Maximilian Pfennig, Doron Callies, Carsten Pape, Jaqueline Drücke, and Lukas Pauscher<br> Adv. Sci. Res., 22, 131–148, https://doi.org/10.5194/asr-22-131-2026, 2026<br> In this paper we analyse the suitability of different reanalyses and meso-scale models for simulating wind energy in Germany. We found that all datasets overestimate energy production, with errors ranging from 5 % to 45 %. This suggests that the underlying models may not accurately reflect average wind conditions. CERRA and ERA5 performed the best, but they also require regional adjustment. Understanding the cause of these differences is crucial for improving weather and wind energy modelling. 2026-04-29T18:47:06+02:00 https://doi.org/10.5194/asr-22-119-2026 <b>Weather intelligence – transforming economies</b><br> David P. Rogers, Alan J. Thorpe, Melanie S. Kappes, and Anna-Maria Bogdanova<br> Adv. Sci. Res., 22, 119–130, https://doi.org/10.5194/asr-22-119-2026, 2026<br> This paper explores advances in weather intelligence as an integral part of the digital transformation of society, enabling everyone to make better informed decisions to avoid harm and enhance economic productivity.  2026-01-30T18:47:06+01:00 https://doi.org/10.5194/asr-22-111-2026 <b>Bridging the gap between users and scientists: challenges of climate service production in a central European case study</b><br> Andrea Böhnisch, Marion Zilker, Inga Beck, Ralf Ludwig, and Gunnar Braun<br> Adv. Sci. Res., 22, 111–117, https://doi.org/10.5194/asr-22-111-2026, 2026<br> Climate services comprise of climate model or observational data that is provided by scientists or authorities to stakeholders who use them in decision-making processes. However, providers and users typically have diverging expectations regarding the data. We here describe various aspects of the gap between needs and offers that were identified in two workshops in the Main River catchment (central Germany). To bridge the gap, we propose a framework that can guide future stakeholder dialogues. 2026-01-27T18:47:06+01:00 https://doi.org/10.5194/asr-22-103-2025 <b>Response of the atmospheric boundary layer to SST variability in a coupled simulation in the Atlantic trades</b><br> Alessandro Storer, Matteo Borgnino, Agostino Niyonkuru Meroni, Fabien Desbiolles, Carlos Conejero, Lionel Renault, and Claudia Pasquero<br> Adv. Sci. Res., 22, 103–110, https://doi.org/10.5194/asr-22-103-2025, 2025<br> We looked into how a numerical experiment represents the interactions between the air and the sea at scales of about 100–1000 km. We found that slight changes in sea surface temperature (SST) drive dramatic modifications in evaporation rates from the sea surface. Cold sea patches tend to cool down the air and to keep moisture trapped within the lower atmospheric layers. Warmer SST, instead, makes them more buoyant and inflate with drier air, thus diluting moisture over thicker air layers. 2025-12-15T18:47:06+01:00 https://doi.org/10.5194/asr-22-97-2025 <b>Intercomparison of measurements at climate reference stations in Germany on the influence of funnel heating of a precipitation device</b><br> Isabel Knerr, Karsten Friedrich, and Florian Imbery<br> Adv. Sci. Res., 22, 97–102, https://doi.org/10.5194/asr-22-97-2025, 2025<br> Long-term series of precipitation data are important for e.g. the precise quantification of climate change. Such time series should be consistent, but changes in the measurement conditions can't always be avoided. Parallel measurements are carried out at German climate reference stations in order to analyse the effects of changes in the measuring systems, e.g. when switching the device to another. In this study, the influence of funnel heating on precipitation measurement  was analysed. 2025-11-24T18:47:06+01:00 https://doi.org/10.5194/asr-22-87-2025 <b>How to best evaluate and communicate the value of severe weather warnings?</b><br> Kathrin Wapler and Anders Sivle<br> Adv. Sci. Res., 22, 87–95, https://doi.org/10.5194/asr-22-87-2025, 2025<br> The question of how to best evaluate and communicate the value of weather warnings was addressed by a survey. This included questions with respect to the relevance of various aspects of a warning, the potential benefit of providing information on warning quality, the type of useful information and suitable ways of providing such information. Apart from the core information of warnings (time, place and severity) impact information and behavioural advice are seen to add value to a warning. 2025-11-17T18:47:06+01:00 https://doi.org/10.5194/asr-22-69-2025 <b>Evaluation of ERA5, COSMO-REA6 and CERRA in simulating wind speed along the French coastline for wind energy applications</b><br> Anindita Patra, Boutheina Oueslati, Tessa Chevallier, Paul Renaud, Youen Kervella, and Laurent Dubus<br> Adv. Sci. Res., 22, 69–85, https://doi.org/10.5194/asr-22-69-2025, 2025<br> In this study, the quality of 10 and 100 m wind speeds from three different reanalyses (global and regional) are evaluated along the different coasts of France. The evaluation show that Copernicus Regional Reanalysis for Europe (CERRA) has a high skill for surface wind speed on the three French seafronts, as well as for offshore wind speed at 100 m. Thus, CERRA appears to be the optimal reanalysis to use as a reference for offshore wind studies over the French maritime zone. 2025-11-14T18:47:06+01:00 https://doi.org/10.5194/asr-22-59-2025 <b>Improving wind power forecasts in the Belgian North Sea with a wind farm parameterization and a neural network</b><br> Dieter Van den Bleeken, Geert Smet, Joris Van den Bergh, Idir Dehmous, Daan Degrauwe, Michiel Van Ginderachter, and Alex Deckmyn<br> Adv. Sci. Res., 22, 59–67, https://doi.org/10.5194/asr-22-59-2025, 2025<br> To better predict offshore wind energy in Belgium, we improved the Royal Meteorological Institute (RMI) weather model by directly incorporating the effects of wind turbines. We also used AI to account for wind farm wake effects, where turbines slow down wind for other turbines. By combining physics-based models with a neural network trained on observations from the Belgian Offshore Zone, we achieved more accurate forecasts. This helps ensure a stable power grid and supports the growing role of offshore wind in our energy mix. 2025-10-21T18:47:06+02:00 https://doi.org/10.5194/asr-22-53-2025 <b>Wind and solar PV generation ramping events from farm to national level: the case of Ireland</b><br> Aina Maimó Far, Conor Sweeney, and Damian Flynn<br> Adv. Sci. Res., 22, 53–58, https://doi.org/10.5194/asr-22-53-2025, 2025<br> Renewable energy is becoming more common, but its variability creates challenges in keeping electricity supply stable. This study examines how changes in energy generation, known as ramps, occur, how they can be modelled and the associated skill. By analyzing wind and solar power in Ireland, we find that using a mix of sources reduces extreme fluctuations and helps supply stability. Our results also stress the benefits of energy diversity and the challenges of modelling changes at a local scale. 2025-09-08T18:47:06+02:00 https://doi.org/10.5194/asr-22-39-2025 <b>Bridging the gap between ensemble forecasting and end-user needs for decision-making on high-impact events</b><br> Matteo Ponzano, Bruno Joly, Isabelle Beau, Elvis Renard, and Gregory Fifre<br> Adv. Sci. Res., 22, 39–52, https://doi.org/10.5194/asr-22-39-2025, 2025<br> Weather forecasts that include uncertainty can be difficult to interpret and apply to real decisions. This study presents simplified and user-friendly tools developed in collaboration with professionals to make probabilistic forecasts more accessible. Tested to heat stress during the Paris 2024 Olympic and Paralympic Games and late frost in vineyards, these tools help anticipate risks and support earlier, more informed, and more effective responses. 2025-07-29T18:47:06+02:00 https://doi.org/10.5194/asr-22-19-2025 <b>Occurrence of tornado outbreaks influenced by solar wind–magnetosphere–ionosphere–atmosphere coupling</b><br> Paul Prikryl and Vojto Rušin<br> Adv. Sci. Res., 22, 19–38, https://doi.org/10.5194/asr-22-19-2025, 2025<br> A link between the solar wind and the occurrence of large tornado outbreaks is found. The solar wind coupling to the Earth’s magnetic field deposits energy into the upper atmosphere at high latitudes. We consider the role of aurorally generated atmospheric gravity waves in the release of instabilities contributing to development of synoptic-scale weather conditions favoring formation of supercells in a strong wind shear environment and high tornado occurrence.  2025-07-18T18:47:06+02:00 https://doi.org/10.5194/asr-22-13-2025 <b>The influence of absorbing aerosols on the morning PBL growth dynamic in the EDMF-AERO modeling framework</b><br> Grzegorz M. Florczyk and Krzysztof M. Markowicz<br> Adv. Sci. Res., 22, 13–18, https://doi.org/10.5194/asr-22-13-2025, 2025<br> Our study investigates how air pollution affects lower troposphere behavior. While the overall height of this layer did not change significantly under heavy pollution, we found a slight delay in the start of air movement and a rapid rise of warm air pockets. We also found out that absorbing aerosols warms the air despite blocking sunlight. For the layer height, no dominant effect was found. This research improves our understanding of how pollution influences atmospheric dynamics. 2025-07-17T18:47:06+02:00 https://doi.org/10.5194/asr-22-9-2025 <b>A Call to Action: Seven recommendations to boost public engagement and decision-making on climate change</b><br> Tomas Molina and Ernest Abadal<br> Adv. Sci. Res., 22, 9–11, https://doi.org/10.5194/asr-22-9-2025, 2025<br> Efforts to meet the Paris climate goals are falling short. This letter proposes seven ways to boost public engagement and better decisions: clearer scientific reports, hopeful messages, countering false information, climate education, local action in workplaces, open and fair leadership, and focusing on adapting to climate change to also encourage cutting emissions. These strategies blend communication, policy, and community action for a stronger global climate response. 2025-07-10T18:47:06+02:00 https://doi.org/10.5194/asr-22-1-2025 <b>On the use of disdrometer data for characterization of precipitation episodes in the Basque Country</b><br> Santiago Gaztelumendi, Joseba Egaña, and José Antonio Aranda<br> Adv. Sci. Res., 22, 1–8, https://doi.org/10.5194/asr-22-1-2025, 2025<br> Measurements are crucial for understanding atmospheric processes, water cycles, and climate. This paper focuses on optical disdrometer measurements to study precipitation complexity at the surface, analyzing precipitation episodes in the Basque Country. Using 1-minute disdrometer data, key characteristics like duration, intensity, particle count, and rain amount are examined for episodes previously established through aggregation of minute data. 2025-06-12T18:47:06+02:00 https://doi.org/10.5194/asr-21-49-2024 <b>Climate Change Scenarios for the Basque Country: wind, humidity and radiation</b><br> Maialen Martija-Díez, Roberto Hernández, José Daniel Gómez de Segura, and Santiago Gaztelumendi<br> Adv. Sci. Res., 21, 49–61, https://doi.org/10.5194/asr-21-49-2024, 2024<br> This paper explores the projected changes on wind, relative humidity and solar radiation in future scenarios for the Basque Country. This work is part of the UrbanKlima2050 initiative and aims to provide a more comprehensive characterization of future climate change impacts in the region, and thus, improve the resiliency of the territory. The main results show a decrease in both wind and relative humidity by the end of this century, while solar radiation tends to increase. 2024-12-20T18:47:06+01:00 https://doi.org/10.5194/asr-21-41-2024 <b>The Basque Impact Weather Catalogue</b><br> Santiago Gaztelumendi, Joseba Egaña, Miriam Ruiz, and Eguzkiñe Iturrioz<br> Adv. Sci. Res., 21, 41–48, https://doi.org/10.5194/asr-21-41-2024, 2024<br> We presents the Basque Country Impact Weather Catalogue, recording detailed information on adverse weather events and their environmental impacts. It includes context, hazard/risk, and impact sections, utilizing data from Euskalmet, Emergency, Media, Insurance, etc. Standardized information enables qualitative and quantitative analysis feasibility for events spanning the 21st century. The paper details catalogue design, structure, and implementation steps. 2024-10-30T18:47:06+01:00 https://doi.org/10.5194/asr-21-27-2024 <b>Characterization of hydrometeorological events and flood impacts in the Basque Country</b><br> Santiago Gaztelumendi, Joseba Egaña, and Kepa Otxoa de Alda<br> Adv. Sci. Res., 21, 27–39, https://doi.org/10.5194/asr-21-27-2024, 2024<br> This study examines floods in the Basque Autonomous Community from 2000 to 2021, assessing damages, weather conditions, and other factors. It uses data from the Spanish Insurance Compensation Consortium and the AWS network, analyzing diverse datasets to extract indicators. Visual analytics are used for analysis and characterization. 2024-10-25T18:47:06+02:00 https://doi.org/10.5194/asr-21-19-2024 <b>Lagrangian model with heat-carrying particles</b><br> Enrico Ferrero, Bianca Tenti, and Stefano Alessandrini<br> Adv. Sci. Res., 21, 19–25, https://doi.org/10.5194/asr-21-19-2024, 2024<br> A new plume rise scheme based on heat transport by particles was presented: the entrainment is simulated by the mixing of two fluids (air and plume particles) with different temperatures and the resulting temperature is given by Richmann's law. The new algorithm is compared with the one that is currently included in SPRAY-WEB by Alessandrini et al. (2013). The new scheme seems to behave better when the ambient wind speeds are higher, but the asymptotic behavior is correct even with lower speeds. 2024-08-02T18:47:06+02:00
