A multiscale analysis, where the historical and future precipitation data from the CORDEX project were used as input in a hydrological model (HEC-HMS) that, in turn, feeds a 2D hydraulic model (Iber+), was applied to the case of the Miño-Sil basin (NW Spain), specifically to Ourense city, in order to analyze future changes in flood hazard. Detailed flood maps indicate an increase in the frequency and intensity of future floods, implying an increase in flood hazard in important areas of the city.

Extreme events have increased in the last few decades; having a good estimation of the outflow of a reservoir can be an advantage for water management or early warning systems. This study analyzes the efficiency of different machine learning techniques to predict reservoir outflow. The results obtained showed that the proposed models provided a good estimation of the outflow of the reservoirs, improving the results obtained with classical approaches.

This study uses Lagrangian moisture tracking and high-resolution weather simulations to trace moisture sources for Storm Ianos (Sept 2020). The analysis identified the Ionian Basin and southwestern Balkans as the primary sources, with secondary contributions from the surrounding seas. Large transport moisture traveled via three main pathways, with the Marmara-Black Sea route most significant. For record-breaking rainfall local evaporation over Greece and the Ionian Sea dominated moisture uptake.

Understanding climate change is crucial, but global models lack fine detail for local assessments. Regional climate models improve accuracy by simulating climate at higher resolution. This study compares two approaches: one continuous and one resetting daily to reduce errors and speed up processing. Both perform well and similarly, but the reinitialized method is 30 times more efficient. Its lower cost makes it a promising option for high-resolution climate modelling and regional predictions.

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.

European windstorms regularly cause damage to natural and human-made environments, leading to high socio-economic losses. For the first time, we compare estimates of these losses using a meteorological loss index (LI) and the insurance loss (catastrophe) model of Aon Impact Forecasting. We find that LI underestimates high-impact windstorms compared to the insurance model. Nonetheless, due to its simplicity, LI is an effective index, suitable for estimating impacts and ranking storm events.

Simultaneous heatwaves or cold spells in remote geographical regions have potentially far-reaching impacts on society and the environment. Despite this, we have little knowledge of when and where these extreme events have occurred in the past decades. In this paper, we present a summary of past simultaneous heatwaves or cold spells and provide a computer program to enable other researchers to study them.

Landslides are complex phenomena causing important impacts in vulnerable areas, and they are often triggered by rainfall. Here, we develop a new approach that uses information on the temporal clustering of rainfall, i.e. multiple events close in time, to detect landslide events and compare it with the use of classical empirical rainfall thresholds, considering as a case study the region of Lisbon, Portugal. The results could help to improve the prediction of rainfall-triggered landslides.

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.

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.

Atmospheric blocking is associated with stationary, self-sustaining and long-lasting high-pressure systems. They can cause or at least influence surface weather extremes, such as heat waves, cold spells, heavy precipitation events, droughts or wind extremes. The location of the blocking determines where and what type of extreme event will occur. These relationships are also important for weather prediction and may change due to global warming.

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.

Extensive, long-standing dry and wet episodes are frequent climatic extreme events (EEs) in the Iberian Peninsula (IP). A method for ranking regional extremes of persistent, widespread drought and wet events is presented, using different SPEI timescales. Results show that there is no region more prone to EE occurrences in the IP, the most extreme extensive agricultural droughts evolve into hydrological and more persistent extreme droughts, and widespread wet and dry EEs are anti-correlated.

Short summary
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.
The present study focuses on an in-depth analysis of floods in the lower section of the Tagus...
