The impact of winter atmospheric blocking over the Ural Mountains region (UB) coincident with different phases North Atlantic Oscillation (NAO) on sea ice variability Barents and Kara Seas (BKS) in is investigated. It found that UB conjunction positive phase NAO (NAO+) leads to strongest decline. During this composites trajectory analyses reveal an efficient moisture pathway BKS from mid-latitude near Gulf Stream Extension where water vapor abundant due high surface temperatures. NAO+-UB...
Winter Arctic sea-ice concentration (SIC) decline plays an important role in amplification which, turn, influences ecosystems, midlatitude weather and climate. SIC over the Barents-Kara Seas (BKS) shows large interannual variations, whose origin is still unclear. Here we find that variations winter BKS have significantly strengthened recent decades likely due to increased amplitudes of El Niño-Southern Oscillation (ENSO) a warming La Niña leads enhanced Atlantic Hadley cell positive phase...
Abstract In recent decades boreal wildfires have occurred frequently over eastern Siberia, leading to increased emissions of carbon dioxide and pollutants. However, it is unclear what factors contributed increases in these wildfires. Here, using the data we show that background Siberian Arctic warming (BAW) related summer Russian sea-ice decline accounts for ~79% increase vapor pressure deficit (VPD) controls Siberia 2004-2021 with remaining ~21% internal atmospheric variability associated...
Abstract This study investigates how El Niño‐Southern Oscillation (ENSO) modulates winter cold anomalies over central Eurasia (CE) using reanalysis data during 1950–2019. It is found that ENSO can significantly influence air temperature CE mainly through modulating the strength and location of cyclonic anomaly Ural blocking (UB) or long‐lived UB events. A strong (weak) on southeastern (eastern) side Mountains tends to occur midlatitude (high‐latitude) La Niña (El Niño) winters. Such...
Abstract In recent decades, the winter surface air temperature (SAT) anomaly in Northern Hemisphere has exhibited a warm Arctic‐cold Eurasia (WACE) dipole pattern and this undergone significant decadal variation. paper, physical cause of variability WACE is explored, it shown to be mediated by phases Pacific Decadal Oscillation (PDO) Atlantic Multidecadal (AMO). Although negative PDO (PDO − ) or positive AMO (AMO + favors pattern, meridional structure significantly influenced whether...
Abstract In the mid–high latitude atmosphere, instability of planetary waves characterizes enhanced wave activity or amplified large‐scale waviness leading to increased regional weather extremes. this paper, a nonlinear Schrödinger equation is derived describe evolution waves. Then consequences Arctic amplification (AA)‐induced meridional background potential vorticity (PV y ) changes on modulational are examined. It found that uniform trains mainly results from presence high‐order...
Abstract Summer heatwaves over Europe, which can cause many deaths and severe damage, have become increasingly frequent central eastern Europe western Russia in recent decades. In this paper, we estimate the contributions of warming due to increased greenhouse gases (GHG) nonlinear variations correlated with Atlantic Multidecadal Oscillation (AMO) observed heatwave trend during 1980–2021, when GHG‐induced exhibits a linear trend. It is found that contributes ∼57% European while cold‐to‐warm...
Abstract In recent decades, winter Arctic sea-ice concentration (SIC) has experienced a most prominent decline over Barents-Kara Seas (BKS). However, what regulates the time scale and spatial structure of SIC variability Eurasian is unclear. Here, we find that exhibits two major modes: decadal dipole mode with antiphase variation between BKS East Greenland (EG), interannual monopole in-phase EG. This mainly results from interdecadal changes in ocean heat transports (OHTs) through Barents Sea...
ABSTRACT On February 22, 2023, North America experienced an unusual weather phenomenon characterised by extreme cold in the west and warmth east, reflecting a surface air temperature (SAT) seesaw pattern that significantly impacted human activities region. Utilising reanalysis data, we analysed this case as well similar events long‐term climate records. The results indicate mode is caused hybrid evolution of atypical Pacific Oscillation (NPO) Pacific‐North American (PNA) phase relationships,...
Abstract In this paper, we investigate the contrasting evolutionary behaviors and weather impacts of Greenland blocking Euro-Atlantic blocking. The comprehensive analysis reveals that is characterized by substantial amplitude, a prolonged lifespan, notable westward movement, accompanied significant warming over western cooling eastern North America northern Europe. contrast, remains quasi stationary, has shorter duration, features smaller resulting in only mild southern We elucidate dynamic...

By analyzing characteristics solitary media comparing with physical experiment's results, it can be found that flume has good accuracy generation propagation. This focuses comparative analysis topography. It...
Abstract Winter surface air temperature (SAT) over North America exhibits pronounced variability on subseasonal, interannual, decadal, and interdecadal time scales. Here, reanalysis data from 1950–2017 are analyzed to investigate the atmospheric ocean conditions associated with its subseasonal interannual variability. Detrended daily SAT reveal a known warm west/cold east (WWCE) dipole midlatitude cold north/warm south (CNWS) eastern America. It is found that while Pacific blocking (PB)...
This study investigates why the Arctic winter sea ice loss over Barents–Kara Seas (BKS) is accelerated in recent decade. We first divide 1979–2013 into two time periods: 1979–2000 (P1) and 2001–13 (P2), with a focus on P2 difference between P1 P2. The results show that during P2, rapid decline of BKS related not only to high surface temperature (SST) BKS, but also increased frequency, duration, quasi-stationarity Ural blocking (UB) events. Observational analysis reveals UB tends become quasi...
Winter Arctic sea-ice concentration (SIC) decline plays an important role in amplification which, turn, influences ecosystems, midlatitude weather and climate. SIC over the Barents-Kara Seas (BKS) shows large inter- annual variations, whose origin is still unclear. Here we find that interannual variations winter BKS have significantly strengthened recent decades likely due to increased amplitudes of El Niño-Southern Oscillation (ENSO) a warming La Niña leads...
