Historical reanalyses that span more than a century are needed for wide range of studies, from understanding large‐scale climate trends to diagnosing the impacts individual historical extreme weather events. The Twentieth Century Reanalysis (20CR) Project is an effort fill this need. It supported by National Oceanic and Atmospheric Administration (NOAA), Cooperative Institute Research in Environmental Sciences (CIRES), U.S. Department Energy (DOE), facilitated collaboration with...
One of the few long instrumental records available for Arctic is Svalbard Airport composite series that hitherto began in 1911, with observations made on Spitsbergen, largest island Archipelago. This record has now been extended to 1898 inclusion by hunting and scientific expeditions. Temperature observed almost continuously since 1898, although at different sites. It therefore possible create one covering period 1898–2012, this valuable new presented here. The reveals large temperature...
Abstract The performance of a new historical reanalysis, the NOAA–CIRES–DOE Twentieth Century Reanalysis version 3 (20CRv3), is evaluated via comparisons with other reanalyses and independent observations. This dataset provides global, 3-hourly estimates atmosphere from 1806 to 2015 by assimilating only surface pressure observations prescribing sea temperature, ice concentration, radiative forcings. Comparisons observations, reanalyses, satellite products suggest that 20CRv3 can reliably...
Abstract Instrumental meteorological measurements from periods prior to the start of national weather services are designated “early instrumental data.” They have played an important role in climate research as they allow daily decadal variability and changes temperature, pressure, precipitation, including extremes, be addressed. Early data can also help place twenty-first century climatic into a historical context such defining preindustrial its variability. Until recently, focus was on...
The Svalbard Airport composite series spanning the period from 1898 to present represents one of very few long-term instrumental temperature High Arctic. A homogenized monthly is available since 2014. Here we increase resolution a daily basis, and further digitization historical data has reduced uncertainty series. most pronounced changes in 120-year record occur during last three decades. For 1991–2018 number days warmer than 0 5 °C increased by 25 (21%) 22 (59%), respectively, per year...
Abstract There is a growing need for past weather and climate data to support science decision-making. This paper describes the compilation construction of global multivariable (air temperature, pressure, precipitation sum, number days) monthly instrumental database that encompasses substantial body known early time series. The dataset contains series compiled from existing databases start before 1890 (though continuing present) as well large amount newly rescued data. All underwent quality...
A detailed analysis of the spatial and temporal changes in mean seasonal annual surface air temperatures over period instrumental observations Arctic is presented. In addition, role atmospheric circulation controlling decadal-scale temperature investigated. Mean monthly anomalies data from 37 Arctic, 7 sub-Arctic 30 grid-boxes were used for analysis. The presented shows that observed variations real (defined on basis climatic as opposed to other criteria, e.g. astronomical or botanical) are...
ABSTRACT In this article, the results of an investigation into air temperature conditions on Svalbard in period 1 September 2010 to 31 August 2011 are presented. For period, parallel measurements have been made as many 30 sites. On basis unique set data it was possible study, detail, spatial distribution different thermal characteristics [mean temperature, diurnal range (DTR), day‐to‐day variability, degree climate continentality, etc.] Svalbard. Such knowledge whole not previously available...
We monitored leaf phenology and xylogenesis of 12 Pedunculate oaks in northern Poland 2014. hypothesized that the individual trees, which differed size, age habitat (tree stand or gap), also diverged terms seasonal patterns xylogenesis. The samples used for wood formation observations were collected most frequently during early phenophases (from March to end June). transverse sections cambial region cut with a sledge microtome. counted number cells, measured width xylem increment assessed...
Daily temperature measurements from six meteorological stations along the coast and fjords of western Spitsbergen have been digitized quality controlled in a Norwegian, Russian Polish collaboration. Complete daily data series reconstructed back to 1948 for all stations. One station's monthly has previously extended 1898 is included this study. The long-term show large variability on with colder periods 1910s 1960s warmer 1930s, 1950s 21st century. most recent years are warmest ones...
Abstract A detailed analysis of the spatial and temporal changes in mean seasonal annual surface air temperature (SAT) Arctic is presented mainly for period 1951–2005. Mean homogenized complete series SAT from up to 35 stations were used analysis. The focus this paper on 11 years 1995–2005, a which saw dramatic warming (>1˚C values relation 1951–90 mean). An abrupt rise occurred mid-1990s was most pronounced autumn winter (>2˚C). greatest 1995–2005 Pacific Canadian regions (>1˚C),...
Climate change is exacerbating the risk of occurrence extreme weather. This study has projected in mean and climate conditions Central Poland during near-future (2026-2050), mid-term (2051-2075), far-future (2076-2100) periods under two climate-change scenarios six General Circulation Models (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6). The results showed that, compared to historical reference period (1990-2014), will experience an increase temperature precipitation by...
Scots pine (Pinus sylvestris) is a very common tree in Polish forests, and therefore was widely used as timber. A relatively large amount of available wood allowed long-term chronology to be built up source information about past climate. The analysis reconstructed indexed values mean temperature 51-year moving intervals the recognition coldest periods years 1207–1346, 1383–1425, 1455–1482, 1533–1574, 1627–1646, 1694–1785. extreme wide narrow rings forms complementary method examining...
Rapid ecosystem transitions and adverse effects on services as responses to combined climate human impacts are of major concern. Yet few long-term (i.e. >60 years) quantitative observational time series exist, particularly for ecosystems that have a long history intervention. Here, we combine three environmental pressures (land use, nutrients erosion) with summer winter reconstructions model simulations explore the system dynamics, resilience role disturbance regimes in varved eutrophic...
Recent air temperature changes in the high Arctic (HA) have been investigated based on mean seasonal and annual data calculated for period 1951–2015 two sub-periods 1976–2015 1996–2015. Two kinds of (observational reanalysis) used research. The observational were compared with taken from six reanalysis products (20CRv2c, CERA-20C, ERA-Int, MERRA-2, NCEP-CFSRR, JRA-55). scale HA warming 1996–2015 relative to reference 1951–1990 reached 1.6 °C was greatest autumn (1.9 °C) winter (1.7 °C),...

Abstract. The winter 1788/89 was one of the coldest winters Europe had witnessed in past 300 years. Fortunately, for historical climatologists, this extreme event occurred at a time when many stations across Europe, both private and as part coordinated networks, were making quantitative observations weather. This means that several dozen early instrumental series are available to carry out an in-depth study severe cold spell. While there have been attempts present daily spatial information...
In the era of human-induced climate change, droughts are one extreme events that can severely impact water resources, regional agriculture and ecological environment. A reliable projection for future is crucial with rapid global increase in frequency intensity droughts. This research aims to project Poland by end 21st century. To achieve this, we use a multi-model mean ensemble 26 downscaled bias-corrected high-resolution general circulation models (GCMs) under Shared Socioeconomic Pathways...
