Public granaries served as key infrastructures to improve food security in agrarian societies. The granary data from 15 domains at the Sušice region (southwestern Bohemia) in the period 1789–1849 CE were used to identify years with bad and good grain harvests, which have been further confronted with documentary data and climatic reconstructions. Data used represent the new source of proxy data for historical-climatological research.

Flash floods belong to natural hazards that can be enhanced in frequency, intensity, and impact during recent climate change. This paper presents a complex analysis of spatiotemporal variability and human impacts (including material damage and fatalities) of flash floods in the Czech Republic for the 2001–2023 period. The analysis generally shows no statistically significant trends in the characteristics analyzed.

This bottle of Riesling from the traditional Bassermann Jordan winery in Deidesheim (Germany) is a relic of the premium wine harvested in 1811. It was named “Comet Wine” after the bright comet that year. The study shows that wine quality can be used to infer summer weather conditions over the past 600 years. After rainy summers with cold winds, wines turned sour, while long periods of high pressure led to excellent qualities. Since 1990, only good wines have been produced due to rapid warming.

We present a robust method for identification and classification of global land drought events (GLDEs) based on soil moisture. Two models were used to calculate soil moisture and delimit soil drought over global land from 1980–2022, which was clustered into 775/630 GLDEs. Using four spatiotemporal and three motion-related characteristics, we categorized GLDEs into seven severity and seven dynamic categories. The frequency of GLDEs has generally increased in recent decades.

The newly developed series of wheat, rye, barley, and oats prices from Sušice (southwestern Bohemia) for the period 1725–1824 CE is used to demonstrate effects of weather, climate, socio-economic, and societal factors on their fluctuations, with particular attention paid to years with extremely high prices. Cold spring temperatures and wet conditions from winter to summer were reflected in very high grain prices.

The official mortality data in the Czech Republic in 1919–2022 are used to show long-term fluctuations in the number of fatalities caused by excessive natural cold and heat, lightning, natural disasters, and falls on ice/snow, as well as the sex and age of the deceased, based on certain meteorological, historical, and socioeconomic factors that strongly influence changes in the number and structure of such fatalities. Knowledge obtained is usable in risk management for the preservation of lives.

The Thirty Years' War (from 1618 to 1648 CE), an armed military conflict in Europe, brought extensive devastation to Europe. The paper analyses annual and seasonal temperature, precipitation, and drought patterns, as well as severe weather extremes, based particularly on documentary data, during this event in central Europe to demonstrate their broad impacts on human society and human responses in coincidence with weather and climate during this period of hardship.

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.

We present an analysis of fatalities attributable to weather conditions in the Czech Republic during the 2000–2019 period based on our own database created from newspaper reports, on the database of the Czech Statistical Office, and on the database of the police of the Czech Republic as well as on their comparison. Despite some uncertainties, generally declining trends in the number of fatalities appear for the majority of weather variables. The structure of fatalities is described in detail.

Previous studies related to historical droughts in the Czech Lands showed that the summers of 1531–1540 could represent the driest summer decade of the past 500 years. To confirm this hypothesis, documentary data from central Europe were collected and presented for individual summers and complemented by maps of precipitation and drought distribution to document corresponding weather patterns and their various impacts. The main droughts occurred in 1532, 1534–1536, 1538, and particularly in 1540.

EUFF 2020 database (EUropean Flood Fatalities-FF) contains 2483 flood fatalities (1980–2018) occurred in 8 countries. Gender, age, activity of FF and dynamics of accidents were obtained from documentary sources. 64.8 % of FF were killed by floods killing less than 10 people. Males were more numerous than females due higher proportion of them driving and working outdoors. FF 30–64 years old died traveling to home/work, driving vehicles dragged by water. Elderly people were trapped indoor by flood.

The paper analyses a weather diary of the Reverend Šimon Hausner from Buchlovice in south-east Moravia, Czech Republic, in the 1803–1831 period. From daily weather records, series of numbers of precipitation days, cloudiness, strong winds, fogs, and thunderstorms were created. These records were further used to interpret weighted temperature and precipitation indices. Records of Šimon Hausner represent an important contribution to the study of climate fluctuations on the central European scale.

To reveal sources of variability imprinted in central European drought records, regression and wavelet analysis were applied to 5 centuries of reconstructed data characterizing Czech climate. Mid- to long-term changes in temperature in the North Atlantic and North Pacific were identified as one of the potential sources of drought variations; transient colder and wetter episodes were linked to the effects of large volcanic eruptions.

The paper analyses extreme droughts of the pre-instrumental period (1501–1803) over the territory of the recent Czech Republic. In total, 16 droughts were selected for spring, summer and autumn each and 14 droughts for summer half-year (Apr–Sep). They are characterized by very low values of drought indices, high temperatures, low precipitation and by the influence of high-pressure situations. Selected extreme droughts are described in more detail. Effect of droughts on grain prices are studied.

Careful selection of available moisture-sensitive proxies resulted in a new reconstruction of short-term drought over the Czech Republic during the last 500 years. It consists of a synthesis of four different proxies and its high reconstruction skill demonstrates the clear advantage of a multi-proxy approach. The new chronology of Z-index shows that central Europe experienced the most severe 30-year late spring–early summer period of drought for the last 500 years.

Throughout the last millennium, several cold periods occurred which affected humanity. Here, we investigate an exceptionally cold decade during the 15th century. The cold conditions challenged the food production and led to increasing food prices and a famine in parts of Europe. In contrast to periods such as the “Year Without Summer” after the eruption of Tambora, these extreme climatic conditions seem to have occurred by chance and in relation to the internal variability of the climate system.

April–August temperature reconstruction for the Czech Lands based on grape-harvest dates in the 1499–2012 period constitutes a further important contribution to the better understanding of long-term spatiotemporal temperature variability in central Europe and includes the very long overlap period (1801–2012) used for calibration and verification, the consistent dominance of Pinot varieties through time, and the stability of vineyard management throughout the period reconstructed.

The paper deals with climatic and human impacts of the strong Tambora (Indonesia) volcanic eruption in April 1815 over the Czech Lands territory based on analysis of documentary data and instrumental records. While climatic effects were related particularly to summers 1815 and 1816 (1816 is known as "a Year Without Summer"), quite important were societal impacts represented after bad harvest by steep increase in prices and shortages of food.

A new data set of 3194 oak (Quercus spp.) ring width samples collected across the Czech Republic and covering the past 1250 years was analysed. The temporal distribution of negative and positive TRW extremes occurring is regular with no indication of clustering. Negative TRW extremes coincided with above-average March-May and June-August temperature means and below-average precipitation totals. Positive extremes coincided with higher summer precipitation, while temperatures were mostly normal.

Historical hydrology combines documentary data with hydrological methods to lengthen flow records to the past centuries. We describe the methodological evolution of historical hydrology under the influence of developments in hydraulics and statistics. Analysis of 45 case studies in Europe show that present flood magnitudes are not unusual in the context of the past, whereas flood frequency has decreased, although some rivers show a reactivation of rare floods over the last two decades.

A data set of instrumental pressure and temperature observations for the early instrumental period (before ca. 1850) is described. This is the result of a digitisation effort involving the period immediately after the eruption of Mount Tambora in 1815, combined with the collection of already available sub-daily time series. The highest data availability is therefore for the years 1815 to 1817. An analysis of pressure variability and of case studies in Europe is performed for that period.

Recent drought events caused enormous damage in Europe. We therefore questioned the existence and effect of current drought management strategies on the actual impacts and how drought is perceived by relevant stakeholders. Over 700 participants from 28 European countries provided insights into drought hazard and impact perception and current management strategies. The study concludes with an urgent need to collectively combat drought risk via a European macro-level drought governance approach.

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.

Previous studies related to historical droughts in the Czech Lands showed that the summers of 1531–1540 could represent the driest summer decade of the past 500 years. To confirm this hypothesis, documentary data from central Europe were collected and presented for individual summers and complemented by maps of precipitation and drought distribution to document corresponding weather patterns and their various impacts. The main droughts occurred in 1532, 1534–1536, 1538, and particularly in 1540.

The paper analyses a weather diary of the Reverend Šimon Hausner from Buchlovice in south-east Moravia, Czech Republic, in the 1803–1831 period. From daily weather records, series of numbers of precipitation days, cloudiness, strong winds, fogs, and thunderstorms were created. These records were further used to interpret weighted temperature and precipitation indices. Records of Šimon Hausner represent an important contribution to the study of climate fluctuations on the central European scale.

To reveal sources of variability imprinted in central European drought records, regression and wavelet analysis were applied to 5 centuries of reconstructed data characterizing Czech climate. Mid- to long-term changes in temperature in the North Atlantic and North Pacific were identified as one of the potential sources of drought variations; transient colder and wetter episodes were linked to the effects of large volcanic eruptions.

The paper analyses extreme droughts of the pre-instrumental period (1501–1803) over the territory of the recent Czech Republic. In total, 16 droughts were selected for spring, summer and autumn each and 14 droughts for summer half-year (Apr–Sep). They are characterized by very low values of drought indices, high temperatures, low precipitation and by the influence of high-pressure situations. Selected extreme droughts are described in more detail. Effect of droughts on grain prices are studied.

Careful selection of available moisture-sensitive proxies resulted in a new reconstruction of short-term drought over the Czech Republic during the last 500 years. It consists of a synthesis of four different proxies and its high reconstruction skill demonstrates the clear advantage of a multi-proxy approach. The new chronology of Z-index shows that central Europe experienced the most severe 30-year late spring–early summer period of drought for the last 500 years.

Throughout the last millennium, several cold periods occurred which affected humanity. Here, we investigate an exceptionally cold decade during the 15th century. The cold conditions challenged the food production and led to increasing food prices and a famine in parts of Europe. In contrast to periods such as the “Year Without Summer” after the eruption of Tambora, these extreme climatic conditions seem to have occurred by chance and in relation to the internal variability of the climate system.

Historical hydrology combines documentary data with hydrological methods to lengthen flow records to the past centuries. We describe the methodological evolution of historical hydrology under the influence of developments in hydraulics and statistics. Analysis of 45 case studies in Europe show that present flood magnitudes are not unusual in the context of the past, whereas flood frequency has decreased, although some rivers show a reactivation of rare floods over the last two decades.

A data set of instrumental pressure and temperature observations for the early instrumental period (before ca. 1850) is described. This is the result of a digitisation effort involving the period immediately after the eruption of Mount Tambora in 1815, combined with the collection of already available sub-daily time series. The highest data availability is therefore for the years 1815 to 1817. An analysis of pressure variability and of case studies in Europe is performed for that period.

Glaciers in the European Alps have been retreating since the 1850s. Monitoring glacier mass balance is vital for understanding global changes, but only a few glaciers have long-term data. This study aims to reconstruct the mass balance of the Silvretta Glacier in the Swiss Alps using stable isotopes and tree ring proxies. Results indicate increased glacier mass until the 19th century, followed by a sharp decline after the Little Ice Age with accelerated losses due to anthropogenic warming.

We study the climate signal in long harvest series from across Europe between the 16th and 18th centuries. The climate–harvest yield relationship is found to be relatively weak but regionally consistent and similar in strength and sign to modern climate–harvest yield relationships. The strongest climate–harvest yield patterns are a significant summer soil moisture signal in Sweden, a winter temperature and precipitation signal in Switzerland, and spring temperature signals in Spain.

We digitized dozens of weather journals containing temperature measurements from in and around Bern and Zurich. They cover over a century before the creation of a national weather service in Switzerland. With these data we could create daily temperature series for the two cities that span the last 265 years. We found that the pre-industrial climate on the Swiss Plateau was colder than suggested by previously available instrumental data sets and about 2.5 °C colder than the present-day climate.

This study investigates the possibility of inferring information on aerosol optical depth from photographs of historic paintings. The idea – which has been applied in previous studies – is very interesting because it would provide an archive of the atmospheric aerosol loading covering many centuries. We show that twilight colours depend not only on the aerosol optical thickness, but also on several other parameters, making a quantitative estimate of aerosol optical depth very difficult.

Descriptions of climate held in archives are a valuable source of past climate variability, but there is a large potential for error in assigning quantitative indices (e.g. −2, v. dry to +2, v. wet) to descriptive data. This is the first study to examine this uncertainty. We gave the same dataset to 71 postgraduate students and 6 professional scientists, findings that error can be minimized by taking an average of indices developed by eight postgraduates and only two professional climatologists.

How did cities respond to drought during the 17th century? This article studies the strategies followed by the city government of Barcelona during the severely dry period from 1620 to 1650. Beyond the efforts to expand urban water supply sources and to improve the maintenance of the system, the city government decided to compile knowledge about water infrastructure into a book and to restrict access to it. This management strategy aimed to increase the city's control over water.

A historical drought series (since 1200 CE) for Shenyang, NE China, shows 20th century droughts comparable in magnitude to recent severe droughts. Drought resilience driven by early 20th century societal/cultural changes reduced loss of life compared with the 1887 and 1891 droughts. A longer temporal analysis from integrated precipitation and historical records shows an earlier onset to droughts. Regional standardised precipitation indices could provide early warnings for drought development.

A new study on droughts in Germany since 1500 reveals the long-term trend of single extreme events, as well as drier periods. Extreme droughts appeared in 1540, 1590, 1615, 1706, 1834, 1893, 1921, 1949 and 2018. Like today, droughts had manifold impacts such as harvest failures, water deficits, low water levels and forest fires. This had different societal consequences ranging from famine, disease, rising prices, migration and riots leading to subsidies and discussions on climate change.

This study provides the opportunity to extend climatic records to preindustrial periods in northern Pakistan. The reconstructed March–August PDSIs for the past 424 years, going back to 1593 CE, enable scientists to know how these areas were prone to climatic extremes in the past. The instrumental data are limited in Pakistan; however, the Cedrus deodara tree that preserves physical characteristics of past climatic variabilities can provide insight into the trend of climatic changes.

The paper presents the main features of droughts in Poland in the period 996–2015 based on proxy data (documentary and dendrochronological) and instrumental measurements of precipitation. More than 100 droughts were found in documentary sources from the mid-15th century to the end of the 18th century with a maximum in the second halves of the 17th and, particularly, the 18th century. The long-term frequency of droughts in Poland has been stable for the last two or three centuries.

We developed a new dataset of historical documents by compiling records (rogation ceremonies) from 13 cities in the northeast of the Iberian Peninsula (IP). These records were transformed into quantitative continuous data to develop drought indices (DIs). We regionalized them by creating three DIs (Ebro Valle, Mediterranean, and Mountain), which cover the period from 1650 to 1899 CE. We identified extreme drought years and periods which help to understand climate variability in the IP.

In this paper we present the longest grape harvest date (GHD) record reconstructed to date, i.e. Beaune (France, Burgundy) 1354–2018. Drawing on unedited archive material, the series is validated using the long Paris temperature series that goes back to 1658 and was used to assess April-to-July temperatures from 1354 to 2018. The distribution of extremely early GHD is uneven over the 664-year-long period of the series and mirrors the rapid global warming from 1988 to 2018.

The historical climatology has remarkable research potentialities. However, historical climatology has some methodological limitations. This study presents a new methodology (COST) that allows us to perform climate reconstructions with monthly resolution. The variability of the climatic series obtained are coherent with previous studies. The new proposed method is objective and is not affected by social changes, which allows us to perform studies in regions with different languages and cultures.

The paper analyses extreme droughts of the pre-instrumental period (1501–1803) over the territory of the recent Czech Republic. In total, 16 droughts were selected for spring, summer and autumn each and 14 droughts for summer half-year (Apr–Sep). They are characterized by very low values of drought indices, high temperatures, low precipitation and by the influence of high-pressure situations. Selected extreme droughts are described in more detail. Effect of droughts on grain prices are studied.

In this paper, we apply a new hydro-climatic reconstruction method on the Caniapiscau Reservoir (Canada), compare the obtained streamflow time series against time series derived from dendrohydrology by other authors on the same catchment, and study the natural streamflow variability over the 1881–2011 period. This new reconstruction is based on a historical reanalysis of global geopotential height fields and aims to produce daily streamflow time series (using a rainfall–runoff model).

In this paper we reconstruct the annual temperature anomalies in South Central China from 1850 to 2008, using phenodates of plants, snowfall days, and five tree-ring width chronologies. It is found that rapid warming has occurred since the 1990s, with an abrupt change around 1997, leading to unprecedented variability in warming; a cold interval dominated the 1860s, 1890s, and 1950s; warm decades occurred around 1850, 1870, and 1960; and the warmest decades were the 1990s–2000s.

Short summary
Bark beetle outbreaks are important disturbances to Norway spruce forests. Their meteorological and climatological triggers are analysed for the main oubreaks over the territory of the Czech Republic based on newly created series of such outbreaks, covering the 1781–2021 CE period. The paper demonstrates the shift from windstorms as the main meteorological triggers of past outbreaks to effects of high temperatures and droughts together with windstorms in past decades.
Bark beetle outbreaks are important disturbances to Norway spruce forests. Their meteorological...
