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.

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

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.

An analysis is made of the records made by Spanish observers of a notable aurora on 18 January 1770 in order to study the characteristics of this event. The records indicate that the phenomenon was observed in both continental and insular territories of Spain. In general, observers described the aurora as red in colour, from sunset to midnight. Calculations of the geomagnetic latitudes of the observation locations indicate this aurora was observed over a wide range of abnormally low latitudes.

A record has been found of an "aurora" observed on 27 October 1856 in the Philippines, practically at the magnetic equator. An analysis of this report indicates that it could belong to a "sporadic aurora" because of low magnetic activity at that time. We provide a possible physical mechanism that could explain the appearance of this sporadic, low-latitude aurora, according to the analyses on the observational report and magnetic observations at that time.

An analysis is given of the account of a
globe of fireobserved in Zafra (Spain) in the middle of the 16th century. During a strong storm, Conde Don Pedro observed what he described as a
globe of firethat was directed against the city and abruptly changed course. He attributed the change in course to a miracle. He described neither any damage nor sound.

This work explores the meteorological conditions of the hydro-geomorphologic event of December 1909 that triggered the highest floods in more than 100 years at the Douro river's mouth and caused important social impacts over the Portuguese and Spanish territories.
The study of this extreme event contributes to a comprehensive and systematic synoptic evaluation of the second most deadly hydro-geomorphologic disaster event occurred in Portugal since 1865.

This article provides a first look into the impact of drought in two cities in the eastern Netherlands from 1500 to 1795 on the basis of municipal records. It concludes that the impact of drought was sometimes similar but also different for both cities when focusing on specific aspects, such as water shortage and navigation. This strengthens the view that the impact of droughts could differ highly on a local level, which necessitates more emphasis on regional and local drought reconstructions.

The present paper upgrades our knowledge of Poland’s climate in the period 1001–1500 using multiproxy data. Four new climate reconstructions have been constructed – three based on dendrochronological data (since the 12th century) and one on documentary evidence (since the 15th century). The results should help improve the knowledge of climate change in Europe, particularly in central Europe.

The mid-6th century was one of the coldest periods of the last 2000 years as characterized by great societal changes. Here, we study the effect of the volcanic double event in 536 CE and 540 CE on climate and society in southern Norway. The combined climate and growing degree day models and high-resolution pollen and archaeological records reveal that the northern and western sites are vulnerable to crop failure with possible abandonment of farms, whereas the southeastern site is more resilient.

We present a novel approach to assimilate climate information contained in chronicles and annals from the 15th century to generate climate reconstructions of the Burgundian Low Countries, taking into account uncertainties associated with the descriptions of narrative sources. Our study aims to be a first step towards a more quantitative use of available information contained in historical texts, showing how Bayesian inference can help the climate community with this endeavor.

Short summary
A double volcanic eruption in 536 and 540 CE caused one of the coldest decades during the last 2000 years. We analyzed new climate model simulations from that period and found a cooling of up to 2°C and a sea-ice extent up to 200 km further south. Complex interactions between sea ice and ocean circulation lead to a reduction in the northward ocean heat transport, which makes the sea ice extend further south; this in turn leads to a surface cooling up to 20 years after the eruptions.

Climate field reconstructions (CFRs) estimate spatiotemporal climate conditions hundreds to thousands of years into the past. Assessing CFR skills is critical for improving their interpretation and ultimately for deriving better CFR estimates. We apply new methods for assessing spatiotemporal skill using formalized null hypotheses to derive a detailed assessment of why CFR skill varies across multiple methods, with implications for improving future CFR estimates.

China’s historical typhoon data show that (1) the tracks of typhoons correspond to the north–southward migration of the Intertropical Convergence Zone and phase of the North Atlantic Oscillation, which show a nearly 30-year and a 60-year cycle during the Little Ice Age (LIA) and (2) paleotyphoons made landfall in mainland China 1 month earlier during the Medieval Warm Period than during the LIA.

Short summary
We compare an off-line and an on-line ensemble-based data assimilation method, for the climate of the 17th century. Both schemes perform better than the simulations without DA, and similar skill on the continental and hemispheric scales is found. This indicates either a lack of control of the slow components in our setup or a lack of skill in the information propagation on decadal timescales. The temporal consistency of the analysis in the on-line method makes it generally more preferable.

Short summary
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.
