Assessing the most severe subsistence crisis of the 17th century in the Northwest of the Iberian Peninsula: a meteorological perspective
Abstract. The analysis of climate behavior over centuries reveals how environmental forces shaped society and helps contextualize modern climate trends and future projections. The torrential rains in several regions of the Eastern Atlantic during 1768–1769 triggered the last and most severe agricultural crisis in Galicia and Northern Portugal, resulting in unprecedented mortality. The atmospheric conditions of this historical episode were analyzed using the EKF400v2 paleo-reanalysis dataset, which spans from the 17th century to the early 21st century. From June 1768 to May 1769, the rainfall anomaly in Galicia and Northern Portugal was positive in 11 out of 12 months. Although the rainfall in Northern Portugal appeared less intense than in Galicia, June 1768 had the highest positive rain anomaly of the century, and September 1768 had the second-highest. This excess precipitation agrees with the occurrence of pro-Serenitate rogations and written testimonies indicating an unusually high number of rainy days between June 1768 and May 1769. The atmospheric synoptic patterns for the rainiest months show negative anomalies in both sea level pressure and 500 hPa geopotential height in the northeast Atlantic. These patterns are associated with troughs in the northeastern Atlantic that induce the formation of surface low-pressure systems and hinder the eastward progression of anticyclones into the region, resulting in more frequent episodes of rain and cold than usual.

Dear Authors,
I congratulate the authors on their research.
I would like to make two small comments in this post.
1) If the focus of this study is "to analyze the atmospheric conditions in the Atlantic Arc from June 1768 to May 1769" as written in lines 115-116, then the 18th century should be written in the title (instead of 17th century as in the current one).2) Using uniform time axis in each and every panels in Figs 4, 5 and 6 could facilitate the visual comparison of these very similar plots.

Dear colleague,
Thank you for your interest in the research and for your helpful comments. Regarding point 1, I completely agree, it is a typo, and as for point 2, it makes sense to select the same time axis in all those figures. Both comments will be taken into account in the next version of the manuscript.
