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. 

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.

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.

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.

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.

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.

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.

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.
