The loss of Arctic sea-ice has been implicated with severe cold and snowy mid-latitude winters. However, the mechanisms and a direct link remain elusive due to limited observational evidence. Here we present atmospheric water vapour isotope measurements from Arctic Finland during ‘the Beast from the East’—a severe anticyclonic outbreak that brought heavy snowfall and freezing across Europe in February 2018. We find that an anomalously warm Barents Sea, with a 60% ice-free surface, supplied up…

The last two decades have seen a dramatic decline and strong year-to-year variability in Arctic winter sea ice, especially in the Barents-Kara Sea (BKS), changes that have been linked to extreme

Arctic Snow Isotope Hydrology: A Comparative Snow-Water Vapor Study

The Arctic’s winter water cycle is rapidly changing, with implications for snow moisture sources and transport processes. Stable isotope values (δ18O, δ2H, d-excess) of the Arctic snowpack have

Influence and prediction value of Arctic sea ice for spring Eurasian extreme heat events

In spring, Eurasia has experienced significant warming, accompanied by frequent extreme heat events. Whether the Arctic sea ice has contributed to the variation of spring Eurasian extreme heat events

Hydroclimatic Controls on the Isotopic (δ18 O, δ2 H, d-excess) Traits of Pan-Arctic Summer Rainfall Events

Arctic sea-ice loss is emblematic of an amplified Arctic water cycle and has critical feedback implications for global climate. Stable isotopes (δ18O, δ2H, d-excess) are valuable tracers for

Arctic Ocean Amplification in a warming climate in CMIP6 models

Arctic near-surface air temperature warms much faster than the global average, a phenomenon known as Arctic Amplification. The change of the underlying Arctic Ocean could influence climate through

An NAO-dominated mode of atmospheric circulation drives large decadal changes in wintertime surface climate and snow mass over Eurasia

The leading mode of wintertime atmospheric variability over the North Atlantic-North Eurasia sector is dominated by the North Atlantic Oscillation (NAO) and accounts for more than one third of the

Forecasting lake‐/sea‐effect snowstorms, advancement, and challenges

Lake‐/sea‐effect snow forms typically from late fall to winter when a cold air mass moves over the warmer, large water surface. The resulting intense snowfall has many societal impacts on communities

Permafrost Thermal Dynamics and Cryostratigraphy at Villum Research Station, Station Nord, Eastern North Greenland (81°N)

We provide the northernmost permafrost thermal analysis in Greenland through the ground temperature time series (2014–2021) and cryostratigraphy of two 20‐m deep boreholes (SN1 and SN2) at Villum

The July 2019 European heatwave in a warmer climate: Storyline scenarios with a coupled model using spectral nudging

Extreme weather events are triggered by atmospheric circulation patterns and shaped by slower components, including soil moisture and sea-surface temperature, and by the background climate. This

Hydrology under change: long-term annual and seasonal changes in small agricultural catchments in Norway

In agricultural catchments, hydrological processes are highly linked to particle and nutrient loss and can lead to a degradation of the ecological status of the water. Global warming and land use



The missing Northern European winter cooling response to Arctic sea ice loss

Despite an intensification of NAO− events, reflected by more prevalent easterly flow, sea ice loss does not lead to Northern European winter cooling and daily cold extremes actually decrease; the dynamical cooling from the changed NAO is ‘missing', because it is offset by a thermodynamical effect owing to advection of warmer air masses.

Arctic warming hotspot in the northern Barents Sea linked to declining sea-ice import

The Arctic has warmed dramatically in recent decades, with greatest temperature increases observed in the northern Barents Sea. The warming signatures are not constrained to the atmosphere, but

Consistency and discrepancy in the atmospheric response to Arctic sea-ice loss across climate models

The decline of Arctic sea ice is an integral part of anthropogenic climate change. Sea-ice loss is already having a significant impact on Arctic communities and ecosystems. Its role as a cause of

Weakening of the stratospheric polar vortex by Arctic sea-ice loss.

It is found that decreased sea-ice cover during early winter months (November-December), especially over the Barents-Kara seas, enhances the upward propagation of planetary-scale waves with wavenumbers of 1 and 2, subsequently weakening the stratospheric polar vortex in mid-winter (January-February).

Changing state of Arctic sea ice across all seasons

The decline in the floating sea ice cover in the Arctic is one of the most striking manifestations of climate change. In this review, we examine this ongoing loss of Arctic sea ice across all

Seasonal and Regional Manifestation of Arctic Sea Ice Loss

The Arctic Ocean is currently on a fast track toward seasonally ice-free conditions. Although most attention has been on the accelerating summer sea ice decline, large changes are also occurring in

Vertical Feedback Mechanism of Winter Arctic Amplification and Sea Ice Loss

Detailed physical mechanism of sea ice reduction in winter (December–February) is identified from the daily ERA interim reanalysis data and it is revealed that this feedback process is being amplified at the rate of ~8.9% every year during 1979–2016.

A reconciled estimate of the influence of Arctic sea-ice loss on recent Eurasian cooling

Northern midlatitudes, over central Eurasia in particular, have experienced frequent severe winters in recent decades1–3. A remote influence of Arctic sea-ice loss has been suggested4–14; however,

Influence of sea ice on Arctic precipitation

The independent, direct effect of sea ice on the increase of the percentage of Arctic sourced moisture (or Arctic moisture proportion, AMP) is found, corresponding to increases of 10.9 ± 2.8% and 2.7 ± 1.1%/1 °C of warming in the vapor source regions.
