The month of June 1925 was found to be exceptional in the southwest interior of the Iberian Peninsula due to the large number of thunderstorms and their significant impacts, with serious losses of human lives and material resources. We analyzed this event from different, complementary perspectives: reconstruction of the history of the events from newspapers, study of monthly meteorological variables of the longest series available, and the analysis of the meteorological synoptic situation.

2025 broke wildfire records across European regions. For five extreme fire seasons, we identify the weather, vegetation and management conditions that drove such extreme fires. We found the change in the likelihood and intensity of similar driving “fire weather”, from before global warming to now, and from now to a likely future climate. Summer drought and hot, dry and windy conditions have shifted rapidly, with 2025’s conditions not rare in some regions despite devastating fires.

This article collects and analyzes reports of auroras published in the Extremadura newspaper from 1923 to 2017. We identified 31 news items describing these events, including major auroras in 1926, 1938, 1957, and 1991. This research highlights the value of newspapers in reconstructing past solar activity.

Persistent rains in the eastern Atlantic during 1768–1769 caused the worst agricultural crisis in Galicia and northern Portugal. Using the EKF400v2 paleo-reanalysis dataset, it was found that the rainfall anomaly was positive in 11 out of 12 months. June 1768 saw the highest positive rain anomaly of the century; September 1768 saw the second-highest. The atmospheric synoptic patterns show negative anomalies in sea level pressure and 500 hPa. These patterns induce surface low-pressure systems.

We investigate the synoptic evolution associated with the occurrence of an atmospheric river that led to a 24 h record-breaking extreme precipitation event (120.3 mm) in Lisbon, Portugal, on 13 December 2022. The synoptic background allowed the formation, on 10 December, of an atmospheric river associated with a deep extratropical cyclone and with a high moisture content and an inflow of moisture, due to the warm conveyor belt, throughout its life cycle. The system made landfall on 12 December.

The present study focuses on an in-depth analysis of floods in the lower section of the Tagus River from a hydrodynamic perspective by means of the Iber+ numerical model and on the development of dam operating strategies to mitigate flood episodes using the exceptional floods of February 1979 as a benchmark. The results corroborate the model's capability to evaluate floods in the study area and confirm the effectiveness of the proposed strategies to reduce flood impact in the lower Tagus valley.

This article aims to explore the interaction between tropical cyclones and the ocean in a less studied area regarding these events. Tropical cyclones generally create an area of colder waters behind them, which in turn can contribute to an increase in biological activity. In the Azores region, the intensity, track geometry, and impact area of the cyclones are the most important factors to determine these responses. The speed of the cyclones was found to be more important for biological activity.

The 1921 drought was the most severe drought to hit Europe since the start of the 20th century. Here the climatological description of the drought is coupled to an overview of its impacts, sourced from newspapers, and an analysis of its drivers. The area from Ireland to the Ukraine was affected but hardest hit was the triangle between Brussels, Paris and Lyon. The drought impacts lingered on until well into autumn and winter, affecting water supply and agriculture and livestock farming.

Short summary
We present the earliest records made in San Fernando, very close to Cádiz (SW Spain). Several previous works have already recovered a significant number of meteorological records of interest in these localities. However, more than 40 000 daily meteorological observations recorded at the Royal Observatory of the Spanish Navy (located in San Fernando) were previously unnoticed and remained neither digitized nor studied. We analyze in detail these newly recovered meteorological readings.
We present the earliest records made in San Fernando, very close to Cádiz (SW Spain). Several...
