Sixteen directional atmospheric circulation types (ACTs) from this method were used for the characterization of circulation conditions in Poland. They were determined based on the direction of the geostrophic wind and the distinction between cyclonic and anticyclonic circulation based on shear vorticity. Both circulation indices were calculated based on data from ERA5 reanalysis, namely the 850 hPa geopotential height. Atmospheric circulation types were determined for a total of 195 grid points, including 109 located in Poland. The study presents an analysis of spatial and temporal changes in circulation conditions in the years 1950–2021 in Poland, which indicates an increase in the frequency of anticyclonic circulation in Poland since the 1980s, notably W and NW advection. The Sc, SWc and Wc types stand out among the cyclonic types with the greatest decrease in frequency across the entire territory of Poland. The anticyclonic west circulation stands out for its statistically significant increase in frequency in winter throughout the analyzed area.","PeriodicalId":35736,"journal":{"name":"Acta Geographica Lodziensia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135212414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chemical composition of lake and mire sediments can be used as proxies of past changes in different accumulation environments. Here, I present these proxies that can be used to reconstruct the palaeoenvironment of the past 16,000 years for many mineral-biogenic series from central Poland and establish regional similarities and differences. Past geochemical studies of biogenic sediments from this region were usually carried out in the context of the genesis of: individual accumulation reservoirs, the development of the relief of river valleys and watersheds; they were also used in combination with other methods of palaeoecological research also reconstruct climatic changes in individual phases of the Late Glacial and Holocene. However, due to the complexity of matter circulation in the lithological and hypsometrical diverse transitional zone between the belts of the Polish Uplands and the Polish Lowlands, an analysis was made to determine the relationship between the conditions of biogenic sedimentation at individual sites using selected statistical analyses. In addition to its description of the geochemical variability of biogenic sediments, this analysis was supplemented by its reference to the spatial differentiation in the relationships between geochemical landscapes and the landforms of various orders. In turn, the method of lithogeochemical facies used for several profiles along the transect from the west to the east of the region made it possible to determine: the origin of water supplying the studied biogenic accumulation reservoirs, the range of individual zones of their supply and the conditions of in-flow of allochthonous mineral matter.","PeriodicalId":35736,"journal":{"name":"Acta Geographica Lodziensia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69338822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
