Summary: The study shows that climate models can simulate the correlation between Arctic sea ice and winter NAO, albeit rarely, with winter circulation signals not being driven by sea ice. It suggests that internal variability is more important than sea ice, and circulation anomalies over the Urals emerge as a decisive precursor to the winter NAO signal.

Summary: The Southern Carpathians in Romania exhibit significant warming trends in temperature extremes, with indications of a drying climate trend in some areas. Elevation does not show a strong influence on temperature and precipitation extremes, while longitude plays a significant role in explaining trends in heavy precipitation indices. Changes in large-scale atmospheric circulation, cloudiness, and summer convection are identified as key factors influencing trend behavior and spatial distribution.

Summary: This study proposes a mechanism for the mid-winter reversal of the North Atlantic Oscillation (NAO) from the perspective of local midlatitude air-sea interaction. It reveals the important role of sea surface temperature anomalies (SSTAs) in the reversal of NAO. The study finds that NAO induces SSTAs in early winter, which then feedback on the atmospheric circulation in late winter, resulting in the reversal of NAO. This reversal has significant impacts on air temperature anomalies in Europe and the Caspian Sea area.

Summary: Rock slope failure (RSF) plays a significant role in the Southern Carpathians, indicating the prevailing process domains, tectonic regimes, and climatic variations. The study reveals that both metamorphic bedrock and other lithologies are susceptible to RSF, with a higher occurrence in fluvial contexts rather than glacial ones. The main drivers of RSF in this region are fluvial incision and tectonic uplift.

Summary: This study analyzes the impact of tropical sea surface temperatures (SSTs) on the signal of geopotential heights (GH200) over the North Atlantic-European (NAE) region. The results show that in late winter, the association between ENSO events and geopotential heights is the strongest. The influences of individual tropical basins are also competitive. Additionally, the superposition effect of extratropical North Atlantic SSTs is demonstrated through the modulation of storm tracks. The ENSO signature in the North Atlantic is projected onto the East Atlantic pattern.

Summary: Using data from the past 64 years, this study found that the zonal wind signal associated with the winter-mean North Atlantic Oscillation (NAO) extends into the upper stratosphere more when solar activity is high, and less when solar activity is low. The analysis of momentum and wave-energy budget shows that this extension is driven by eddies and energy conversions between the eddies and zonal-mean flow. These energy transfers are closely related to the enhanced zonal wind. The study suggests that the structural modulation of the NAO due to the solar cycle comes from the increased sensitivity of the wave-mean flow interaction in the stratosphere during high solar activity years.

Summary: Climate models predict an intensification of the wintertime North Atlantic Ocean storm track by the end of the century. This study explores the role of ocean-atmosphere coupling in this intensification, focusing on the effects of thermodynamic and dynamic ocean coupling. Results show that dynamic coupling is the main driver of future TEKE strengthening, while changes in surface heat flux have a smaller impact. Additionally, ocean heat flux convergence increases meridional temperature gradient in the North Atlantic, leading to increased eddy growth rate and strengthening of TEKE. These findings highlight the importance of monitoring and studying changes in ocean heat transport for climate change adaptation strategies.

Summary: Climate during the last glacial period was characterized by abrupt and millennial-scale variations in temperature, especially in Greenland (Daansgard-Oeschger events) and Antarctica (AIM events). This study presents a continuous record of stable isotopes from planktic and benthic foraminifera at a site in the southwestern Iberian margin, providing insights into millennial climate variability (MCV) during the past 1.5 million years. The results demonstrate that MCV was a persistent feature of glacial climate, with modulation by orbital forcing and a strong correlation with North Atlantic surface temperature and deep-water circulation.

Summary: The detailed investigation of a Lower Miocene Plinian pyroclastic sequence in the Bukk Foreland Volcanic Area (BFVA) in Northern Hungary revealed a complete Plinian eruption phase with a pyroclastic succession approximately 50 meters thick. The eruption products include a basal ignimbrite covered by stratified pyroclastic unit indicating a proximal-to-distal source region to the east of BFVA. The correlation of pyroclastic rocks in different locations was supported by lithological, textural, and paleomagnetic similarities.

Summary: Sulfides from lherzolite and wehrlite xenoliths in the Nograd-Gomor Volcanic Field were studied to understand the behavior of chalcophile and siderophile elements. Significant differences were found in the composition and distribution of sulfides between the two xenolith types, suggesting enrichment of sulfides and chalcophile elements in the subcontinental lithospheric mantle due to metasomatism.

Summary: The study concludes that the Danube alluvium, Carpathian Bending, Eastern Carpathian, glaciofluvial, and Black Sea pathways are the main potential sources of loess sediments in the Lower Danube Basin. The geochemical data suggest that the Danube alluvium pathway is the major trajectory for loess in the region, with contributions from the Carpathian Bending pathway in the northeastern part, and possible minor influences from the Black Sea pathway.

Summary: This study investigates high-resolution magnetic properties as paleoclimatic proxies in loess-paleosol sequences, using magnetic susceptibility and luminescence dating to identify characteristics of global climatic transitions. The results highlight the regional response to major climatic transitions and the continuous eolian dust accumulation and soil formation processes in loess regions across the northern hemisphere. Combining magnetic susceptibility with absolute dating provides a more accurate understanding of Pleistocene-Holocene climatic transitions, avoiding potential misinterpretations in records due to simple pattern correlations.

Summary: This study reconstructs changes in vegetation, temperature, and sediment geochemistry in the Subcarpathian belt of the Eastern Carpathians over the past 6.5 thousand years. Pollen and brGDGTs are used as paleothermometers to reconstruct mean annual air temperature (MAAT) and mean temperature above freezing (MAF), respectively. Both proxies show consistent records, with the highest temperatures occurring during the oldest part of the record. The transition from the Middle to the Late Holocene is marked by a prominent temperature decrease, coinciding with Bond events and other climatic factors.

Summary: Recent fluvial tufa carbonates from two valleys in Hungary were studied to examine the suitability of oxygen isotope-based palaeothermometers for tufa deposits and find the most appropriate locations for temperature calculation. A good correlation was found between 1000ln alpha and water temperature near the spring orifice. However, significant differences were observed between calculated and measured temperature values in areas with large seasonal water temperature fluctuations. The stable isotope composition of the measured tufas reflects increasing continentality from west to east in Europe.
