Low-latitude aurorae (LLA) were an uncommon phenomenon not well known or understood in 1780. During our historical manuscript research of high atmospheric phenomena, we came across a document reporting an observation made by the abbot Rozier in Beausejour, France, on 15/08/1780. Thanks to the accuracy of his report, we were able to confirm it was a white, two-band structure LLA. Due to the few existing geomagnetic and solar observations, this is useful new geomagnetic activity proxy data.

Drought events are of great importance in most Mediterranean climate regions, and the impacts caused on rainfed crops are particularly evident. In this study the impacts of drought on two representative rainfed crops in Spain (wheat and barley) are assessed by testing various worldwide drought indices and two datasets at different spatial resolution.

Drought is a major driver of vegetation activity in Spain. Here we used a high-resolution remote-sensing dataset spanning the period from 1981 to 2015 to assess the sensitivity of 23 vegetation types to drought across Spain. Results demonstrate that vegetation activity is controlled largely by the interannual variability of drought. Nevertheless, there are some considerable spatio-temporal variations, which can be linked to differences in land cover and aridity conditions.

We analyzed changes in surface relative humidity (RH) at the global scale from 1979 to 2014 and compared the variability and trends in RH with those in land evapotranspiration and ocean evaporation in moisture source areas across a range of selected regions worldwide. Our results stress that the different hypotheses that may explain the decrease in RH under a global warming scenario could act together to explain recent RH trends.

We found an early record of ball lightning, which was observed in the monastery of Pi (Oliva, southeastern Spain) on 18 October 1619. The ball lightning was observed by at least three people and was described as a “rolling burning vessel” and a “ball of fire”. The ball lightning appeared following a lightning flash, showed a mainly horizontal motion, crossed a wall, smudged an image of the Lady of Rebollet (then known as Lady of Pi) and burnt her ruff, and overturned a cross.

A catastrophic flash-flood event hit the northeastern part of Mallorca in 2018, causing 13 casualties and impacting on the international opinion in one of the most important tourist resorts. The analysis of the rainfall–runoff processes illustrated an unprecedented flashy behaviour in Europe triggering the natural disaster. UAVs and hydrogeomorphological precision techniques were used as a rapid post-catastrophe decision-making tool, playing a key role during the rescue searching tasks.

Africa has been severely influenced by intense drought events, which has led to crop failure, food shortages, famine, epidemics and even mass migration. The current study developed a high spatial resolution drought dataset entirely from satellite-based products. The dataset has been comprehensively inter-compared with other drought indicators and may contribute to an improved characterization of drought risk and vulnerability and minimize drought's impact on water and food security in Africa.

A database of reference evapotranspiration (ETo) was obtained and made publicly available for Spain covering the 1961–2014 period at a spatial resolution of 1.1 km. Previous to ETo calculation, data of required climate variables were interpolated and validated, and the uncertainty was estimated. Obtained ETo values can be used to calculate irrigation requirements, improve drought studies (our main motivation) and study the impact of climate change, as a positive trend was detected.

In order to define a dry period, a threshold for wet days is usually considered to account for measurement errors and evaporation. In the present study, we compare the threshold of 1 mm d−1, the most commonly used threshold, to a time-varying threshold describing evapotranspiration to compare how the risk of extreme dry spells is estimated with both thresholds. Results indicate that considering a fixed threshold can underestimate extreme dry spells during the extended summer.

Two optical disdrometers, OTT Parsivel2 disdrometer and Thies Clima laser precipitation monitor (LPM), are compared. Analysis of 2 years of one-minute replicated data showed significant differences. Thies LPM recorded a larger number of particles than Parsivel2 and a higher proportion of small particles, resulting in higher rain rates and amounts and differences in radar reflectivity and kinetic energy. Possible causes for these differences, and their practical consequences, are discussed.

Spanish PREcipitation At Daily scale (SPREAD) is a new daily gridded precipitation dataset for Spain. It covers the whole territory of peninsular Spain and the Balearic and Canary Islands at a 5 × 5 km spatial resolution for the 1950–2012 period. The research is more than a complex analysis of precipitation in Spain; it provides a product that can be used for both scientific and decision-making policy purposes.

In this work we analyse the recent evolution and meteorological drivers of the atmospheric evaporative demand in the Canary Islands. We found that the reference evapotranspiration increased by 18.2 mm decade−1 – on average – between 1961 and 2013, with the highest increase recorded during summer. This increase was mainly driven by changes in the aerodynamic component, caused by a statistically significant reduction of the relative humidity.

A Lagrangian approach was used to identify the moisture sources for fourteen ice-core sites located worldwide for the present climate. The approach computed budgets of evaporation minus precipitation by calculating changes in the specific humidity along 10-day backward trajectories. The results indicate that the oceanic regions around the subtropical high-pressure centers provide most of moisture, and their contribution varies throughout the year following the annual cycles of the centers.

This paper analyzes the evolution of the Monte Perdido Glacier, Spanish Pyrenees, since 1981. Changes in ice volume were estimated by geodetic methods and terrestrial laser scanning. An acceleration in ice thinning is detected during the 21st century. Local climatic changes observed during the study period do not seem sufficient to explain the acceleration. The strong disequilibrium between the glacier and the current climate and feedback mechanisms seems to be the most plausible explanation.

Forecasts of natural hazards save lives. But the accuracy of forecasts must be evaluated before use. Here we evaluate heavy rainfall advisories over Kenya. We assess their ability to anticipate heavy rainfall and show how well they warned of recent floods which had significant impacts. We find that although they effectively warn of heavy rainfall and flooding, issues such as a lack of spatial detail limit their utility for systematic approaches to preparedness.

This study investigated one case of a tropical-like cyclone over the Mediterranean Sea under present and future climate conditions with a regional climate model. A pseudo global warming (PGW) technique is employed to simulate the cyclone under future climate, and our simulation showed that the cyclone is moderately strengthened by warmer climate. Other PGW simulations where only ocean and atmosphere are warmed reveal the interesting results that both have counteracting effects on the cyclone.

This study investigates hot weather episodes in eight German cities which are statistically associated with increased mortality. Besides air temperature, ozone concentrations partly explain these mortality rates. The strength of the respective contributions of the two stressors varies across the cities. Results highlight that during hot weather episodes, not only high air temperature affects urban populations; concurrently high ozone concentrations also play an important role in public health.

A set of models is developed to forecast hourly probabilities of weather-related road accidents in Germany at the spatial scale of administrative districts. Model verification shows that using precipitation and temperature data leads to the best accident forecasts. Based on weather forecast data we show that skilful predictions of accident probabilities of up to 21 h ahead are possible. The models can be used to issue impact-based warnings, which are relevant for road users and authorities.

Heavy precipitation causes serious losses and several casualties in the western Mediterranean every year. To predict this phenomenon better, we aim at understanding how the models represent the interaction between atmospheric moisture and precipitation by nudging a 10 min, state-of-the-art GPS data set. We found, for the selected case in autumn 2012, that the improvement in the modelling of precipitation stems from relevant variations of atmospheric instability and humidity above 1.5 km.

The Weather Research Forecasting with Chemistry (WRF-Chem) model was modified to include volcanic ash aggregation. The modified WRF-Chem model was run with and without aggregation, and changes in the model output were measured. Changes in the lifetime of volcanic ash a function of the chosen fractal dimension were quantified. A case study using the 2010 eruptions of Eyjafjallajökull revealed that the aggregation modifications result in tephra fallout and ash concentrations near observed values.

We considered the Western Mediterranean Oscillation index (WeMOi) to analyse the occurrence of extreme torrential episodes (≥ 200 mm in 24 h) over Catalonia (NE Iberia) during the 1951–2016 period. Principal results reveal the occurrence of 50 episodes, mainly in autumn, especially during the second 10 d period of October (11–20), coinciding with the most negative WeMOi values of the year. Seasonal changes in these episodes and in WeMOi values might be due to sea warming.

In this study, we corrected Asian Precipitation Highly Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE) in the Yarlung Tsangpo–Brahmaputra River Basin using both linear and nonlinear methods, and their influences on resulting extreme precipitation indices were assessed. Results showed that all methods were able to correct mean precipitation, but their ability to correct wet-day frequency and coefficient of variation were markedly different.

In recent years, heat waves have become more frequent in the world, e.g., in Europe, Australia, China and the US, at huge detriment to human health and natural resources. Thus we establish an integrated index of heat waves and extreme-temperature days to provide unified standards for assessing heat waves and hot years. It provides a clear picture of the evolution and spatial distribution of heat waves and hot years in China.

Severe convective storms are major loss drivers across Europe. We reconstructed several thousand storm tracks from radar reflectivity over a 10-year period for parts of Europe. The tracks were additionally combined with hail reports, reanalysis data, and front detections based on ERA-Interim (ECMWF Reanalysis). It is found that frontal hailstorms on average produce larger hailstones and have longer tracks and that wind shear is important not only for the hail diameter but also for track length.

We have studied changes in winter weather known to trigger road closures and isolation of small seaside communities in northern Norway. We find that snow amounts and heavy snowfall events have increased in the past, while future projections for 2040–2100 show a decrease in snow-related indices. Events of heavy water supply and zero crossings are expected to increase. Our results imply fewer dry-snow-related access disruptions in the future, while wet-snow avalanches and slushflows may increase.

Coastal compound flooding (CF), caused by interacting storm surges and high water runoff, is typically studied based on concurring storm surge extremes with either precipitation or river discharge extremes. Globally, these two approaches show similar CF spatial patterns, especially where the CF potential is the highest. Deviations between the two approaches increase with the catchment size. The precipitation-based analysis allows for considering
local-rainfall-driven CF and CF in small rivers.

The main objective of this paper was to analyze differences in soil moisture responses to drought for each biome of Brazil. For that, we used satellite data from the European Space Agency, from 2009 to 2015. We found an overall soil moisture decline of −0.5 %/year at the country level and identified the most vulnerable biomes of Brazil. This information is crucial to enhance the national drought early warning system, develop strategies for drought risk reduction and soil moisture conservation.

Coastal regions of China feature high population densities as well as flexible structures and are therefore vulnerable to tropical cyclone (TC) damage. A TC is a moving rotating storm with a small occurrence rate at a specific site. Wind anemometers are usually damaged during strong typhoon events, making the record of observed winds an unreliable predictor for design wind speed. This study uses the Monte Carlo simulation to investigate the typhoon wind hazards in coastal regions of China.

Severe convective storms (SCS) and related hail constitute a major atmospheric hazard in various parts of Europe. In our study we identified the regions the most affected by hail over a 10-year period (2005 to 2014) covering France, Germany, Belgium and Luxembourg. A cell-tracking algorithm was computed on remote-sensing data to enable the reconstruction of several thousands of SCS tracks. The location of hail hotspots will help to understand hail formation and improve hail forecasting.

Post-event damage assessment data are used to study the consequences of natural hazards, such as strong convective winds (i.e. tornadoes, downbursts). The information gathered during fieldwork can be used to characterize those events, which is necessary to build up and maintain robust and homogeneous databases of severe weather cases and high-impact weather events. Accordingly, a methodology to carry out damage surveys of strong-convective-wind events is presented in this article.

Impact of assimilation of various observation data set on the forecasts is studied in a mesoscale weather model. The ground-based GNSS Zenithal Total Delay data set providing information on humidity has the largest impact on the analyses and the forecasts. Indeed it represents an evenly spread and frequent data set available at each analysis time over the model domain. Moreover, the reprocessing of these data also improves the forecast quality but this impact is not statistically significant.

We assess a methodology to evaluate and improve intense precipitation forecasting in the southeastern French region. This methodology is based on the use of a 30-year dataset of past forecasts which are analysed using a spatial verification approach. We found that precipitation forecasting is qualitatively driven by the deep-convection parametrization. Locally the model is able to reproduce the distribution of spatially integrated rainfall patterns of the most intense precipitation.

Derechos are widespread, convectively induced severe wind events. A climatology of derechos in Germany is presented. It shows that derechos are not uncommon across the country. Two seasonal peaks indicate a comparable derecho risk in summer and winter. At the same time, we found two different derecho types, a warm- and a cold-season type. We present characteristics of both derecho types that can help forecasters to estimate the potential derecho threat in a given weather situation.

Of severe tropical cyclones (TCs) lead to devastating losses. Nevertheless, to construct a robust risk assessment is difficult based on historical TC records only. This paper addresses this issue by introducing a computationally simple approach, using operational ensemble forecasts to build a physically consistent high-impact TC event set with data equivalent to more than 10 000 years of TC events. This method will be of high relevance for insurance and disaster risk reduction applications.

We designed an index-based insurance (IBI) for drought and flood in rice crops in Babahoyo (Ecuador). We assessed Babahoyo's soil, climatic and topographic variability, finding two homogeneous zones inside this area. We set differentiated insurance premiums according to the particular risk status of each zone. Results demonstrate that this IBI is an efficient risk transfer tool for policyholders. This insurance design could contribute to stabilizing farmers' incomes and rice production.

Models are not particularly skilful at forecasting rainfall more than 15 d in advance. However, they are often better at predicting atmospheric variables such as mean sea-level pressure (MSLP).

In 1876, 1910, and 2005, Switzerland was impacted by extreme rainfall and floods. All events were linked to a Vb cyclone. We test a range of weather model setups (short spinup and standard physics are best) to understand the sensitivity of atmospheric dynamics. The simulated Vb cyclones are (not) well defined for 2005 and 1910 (1876). To reproduce the events, intense moisture flux from the right direction is needed. Storms that slightly deviate from an ideal path produce erroneous precipitation.

Tropical cyclone wind models are often used in engineering applications. However, these models lack the required accuracy when the size of the tropical cyclone is not known. In this paper, new relationships are derived to describe parameters affecting the size. These relationships are formulated using observed data and make it possible to estimate tropical cyclone size and to use this information in tropical cyclone wind models to obtain more reliable estimates of the tropical cyclone winds.

A transition zone often exists between a moist upper river reach and an arid lower reach in a watershed with complex topography. This zone is more suitable for human activities but is difficult to identify in climate classification. We found that a hydrological index overpowers a meteorological index in identifying a transition zone of a watershed in northwestern China, indicating the important role of the land-surface processes and human disturbances in formulating the transition zone.

We have developed a statistical-parametric model of tropical cyclones (TCs), to undertake hazard and risk assessments at continental scales. The model enables users to build an understanding of the likelihood and magnitude of TC-related wind speeds across full ocean basins, but at a fine spatial resolution. The model can also be applied to single events, either scenarios or forecast events, to inform detailed impact assessments.

In order to define a dry period, a threshold for wet days is usually considered to account for measurement errors and evaporation. In the present study, we compare the threshold of 1 mm d−1, the most commonly used threshold, to a time-varying threshold describing evapotranspiration to compare how the risk of extreme dry spells is estimated with both thresholds. Results indicate that considering a fixed threshold can underestimate extreme dry spells during the extended summer.

In this study, we show that both the model horizontal resolution and air–sea flux parameterization can exert a large influence on tropical cyclone intensity simulation but with different impacts on wind structures. We highlight the intensification and contraction of the TC eyewall in response to the reduction of grid spacing. We also suggest that a well-developed eyewall is more conducive to the positive effect of flux formulas on TC development.

Considering flood risk composed of hazard, exposure, and vulnerability from global to local scales, this paper reviews and presents increasing observed flood losses and projections of flood hazard and losses. We acknowledge existence of multiple driving factors and of considerable uncertainty, in particular with regards to projections for the future. Finally, this paper analyses options for flood risk reduction from a global framework to regional and local scales.

The mapping of convective storms in the area of the transboundary Prut River basin was developed using a 15-year radar dataset (2003–2017). The analysis is based on data sampled in successive 6 min scans of the atmosphere, to detect and track the convective storms. The results highlighted a yearly, monthly, and daily variation of convective activity but also spatial distribution patterns. The study of atmospheric convection is important in assessing the risks associated with extreme weather.

Drought events are of great importance in most Mediterranean climate regions, and the impacts caused on rainfed crops are particularly evident. In this study the impacts of drought on two representative rainfed crops in Spain (wheat and barley) are assessed by testing various worldwide drought indices and two datasets at different spatial resolution.

Short summary
We mapped – for the first time – the probability of occurrence of drought over Spain, with the overriding aim of improving current drought assessment, management and mitigation measures, and strategies across the region. Spatially, our estimations suggest a higher probability of extreme drought events in southern and central areas of Spain compared to northern and eastern regions. Nevertheless, there are strong differences among drought indices and drought timescales.
We mapped – for the first time – the probability of occurrence of drought over Spain, with the...
