“…However, a systematic classification of droughts intensity on an ordinal scale based on religious ceremonies could not be made for the present study, due to frequent changes in the liturgical ceremonial or changes in the institutions involved (Silva, 2017). Nevertheless, as in other similar studies conducted in catholic countries (e.g., Piervitali and Colacino, 2001), we found that, in general, the first liturgical initiatives began with prayers (e.g., novenas). Novenas consisted of nine successive days of Pro pluvia prayers followed by Pro pluvia processions 2-3 weeks later if the situation of dry weather and rainfall shortage persisted.…”

“…Domínguez-Castro et al (2008; have reconstructed drought episodes based on Pro pluvia rogation ceremonies from which excellent series have been extracted. These religious activities were organized in catholic countries (Spain, Portugal, Italy, and France) to ask God for rainfall during long-lasting periods of the absence of precipitation, which were interpreted as punishment from God (Martín-Vide and Barriendos, 1995;Barriendos, 1997;Alcoforado et al, 2000;Piervitali and Colacino, 2001;Garnier et al, 2015). Pro serenitate ceremonies begging for the end of severe storms are addressed in other studies.…”

A renewed interest in historical droughts is due to the current climate change issues and also to the recent extreme drought of 2017 in Portugal. This work aims to lengthen the historical drought series and help improve projections for the future. The main droughts of the 18th century in mainland Portugal were identified using mostly direct documentary sources: individual (poems, letters, memoirs, manuscripts and printed newspapers) and institutional (ecclesiastical and administrative), as well as accounts of Pro pluvia ceremonies and processions. All the records had been assembled in the KlimHist database (http://clima.ul.pt/Klimhist-project). A summary statistical analysis of the drought evidence including its impacts was performed to assess its temporal distribution and geographical incidence. A strong precipitation variability was detected, which, similar to the present times, hardly presents trends in long series. The main years of drought during the 18th century in Portugal are highlighted, particularly the severe and long‐lasting 1737–38 and 1753–54 droughts that, together with their atmospheric causes, were studied in detail. There are more drought records for Southern Portugal (SP) than for Northern Portugal (NP). It was also observed that spring March, April and May (MAM) and winter December, January and February (DJF) drought evidence are more frequent in SP, whereas in NP there are more records concerning summer June, July and August (JJA). The results obtained agree with those of others of the Iberian Peninsula (IP). Despite Portugal being a small country, our results confirm the existence of an important climatic boundary between the NP and the SP with different precipitation variability.

“…For Italy, Piervitali and Colacino (2001) reported 50 prayer processions for the relief of droughts, based on records from Erice in western Sicily relating to the 1565-1915 period. These processions were at their most frequent during the 17th century (21 years, compared to only 8 years in the 19th century) and in April (28 years), followed by May and March (a total of 44 years in any spring month).…”

“…Pfister and Brázdil, 1999;Dobrovolný and Barriendos Vallvé (1995) and Barriendos (1997) developed a Drought Rogation Index, taking into account five levels of drought intensity/duration according to the hierarchic system of rogation ceremonies performed in Barcelona (Spain). Rogation ceremonies as dry/wet proxies have been analysed in many papers covering Spain and Portugal (see Domínguez-Castro et al, 2008Fragoso et al, 2018;Tejedor et al, 2018 and references therein), Italy (Piervitali and Colacino, 2001) and France (Garnier, 2014). Rogations are also well-known in former Spanish colonies in Central and South America (e.g.…”

Abstract. The use of documentary evidence to investigate past climatic trends and events has become a recognised approach in recent decades. This contribution presents the state of the art in its application to droughts. The range of documentary evidence is very wide, including: general annals, chronicles, and memoirs, diaries kept by missionaries, travellers and those specifically interested in the weather, the records kept by administrators tasked with keeping accounts and other financial and economic records, legal-administrative evidence, religious sources, letters, marketplace and shopkeepers' songs, newspapers and journals, pictographic evidence, chronograms, epigraphic evidence, early instrumental observations, society commentaries, compilations and books, and historical-climatological databases. These come from many parts of the world. This variety of documentary information is evaluated with respect to the reconstruction of hydroclimatic conditions (precipitation, drought frequency and drought indices). Documentary-based drought reconstructions are then addressed in terms of long-term spatio-temporal fluctuations, major drought events, relationships with external forcing and large-scale climate drivers, socio-economic impacts and human responses. Documentary-based drought series are also discussed from the viewpoint of spatio-temporal variability for certain continents, and their employment together with hydroclimate reconstructions from other proxies (in particular tree-rings) is discussed. Finally, conclusions are drawn and challenges for the future use of documentary evidence in the study of droughts are presented.

“…Natural proxy data (see PAGES Hydro2k Consortium, 2017) may be supplemented by the documentary records generally utilized in historical climatology (Brázdil et al, 2005(Brázdil et al, , 2010 in drought reconstructions. These are usually represented as series for drought frequency covering the last few centuries, usually from the 16th century to the present time or a shorter time period (e.g., Piervitali and Colacino, 2001;Domínguez-Castro et al, 2008Diodato and Bellocchi, 2011;Brázdil et al, 2013;Noone et al, 2017). However, reconstructions of long-term series of drought indices from documentary and instrumental data, as have been done for the Czech Lands from the 16th century (Brázdil et al, 2016a;Možný et al, 2016), still remain the exception.…”

Long-term variability of drought indices in the Czech Lands and effects of external forcings and large-scale climate variability modes

Abstract. While a considerable number of records document the temporal variability of droughts for central Europe, the understanding of its underlying causes remains limited. In this contribution, time series of three drought indices (Standardized Precipitation Index – SPI; Standardized Precipitation Evapotranspiration Index – SPEI; Palmer Drought Severity Index – PDSI) are analyzed with regard to mid- to long-term drought variability in the Czech Lands and its potential links to external forcings and internal climate variability modes over the 1501–2006 period. Employing instrumental and proxy-based data characterizing the external climate forcings (solar and volcanic activity, greenhouse gases) in parallel with series representing the activity of selected climate variability modes (El Niño–Southern Oscillation – ENSO; Atlantic Multidecadal Oscillation – AMO; Pacific Decadal Oscillation – PDO; North Atlantic Oscillation – NAO), regression and wavelet analyses were deployed to identify and quantify the temporal variability patterns of drought indices and similarity between individual signals. Aside from a strong connection to the NAO, temperatures in the AMO and (particularly) PDO regions were disclosed as one of the possible drivers of inter-decadal variability in the Czech drought regime. Colder and wetter episodes were found to coincide with increased volcanic activity, especially in summer, while no clear signature of solar activity was found. In addition to identification of the links themselves, their temporal stability and structure of their shared periodicities were investigated. The oscillations at periods of approximately 60–100 years were found to be potentially relevant in establishing the teleconnections affecting the long-term variability of central European droughts.
