In 2022, western Europe experienced its hottest summer on record and
widespread dry conditions, with substantial impacts on health, water and
vegetation. Here we use a reanalysis to classify daily mean sea level
pressure fields and investigate the influence of synoptic circulations
on the occurrence of temperature extremes and dry days. Summer 2022
featured an above-normal occurrence of anticyclones extending from the
British Isles to the Baltic countries, as well as enhanced easterly,
southerly and low-flow conditions which contributed to the observed
extremes over southern and western Europe. While the hot summer of 2022
is only marginally explained by circulation anomalies, such anomalies
played a key role in the exceptional occurrence of dry days. The
comparison with summer circulation anomalies projected by twenty global
climate models moreover suggests that future circulation changes will
further exacerbate hot and dry extremes over Europe.
Dear Editor, dear Alessandro Samuel-Rosa as second referee, Let me reply to your, Alessandro's comments (ASR) in the sequence of your review: ASR 2: "I agree with the Anonymous Referee #1 when s/he says that the sampled data is insufficient and inappropriate to answer the initial questions and upscale the results tothe entire upland Amazon basin. There is very little indication on why and how thesampling sites were selected or how representative of the entire upland Amazon basinthey are. Sampling along a single year also is insufficient to make statements C1
Dear editor (and possibly dear referee colleague, responsible for those review comments), We as authors are a little bit stupefied by some of the comments since they make assumptions about our work that are neither corroborated by the article itself nor by previous related publications. Referee 1 writes: "... the correct approach would (have been) to preplan a sampling programme, based on statistical evaluation of the number of sites and samples required C1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
