TLDR
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).Abstract:
The mechanism behind the severely cold winters experienced by the mid-latitudes of the Northern Hemisphere in recent years is not fully understood. Here, the authors combine observational analyses and model experiments to reveal a dynamic connection between Arctic sea-ice cover and the polar stratosphere.read more

More Evidence Linking Arctic Amplification to Extreme Weather in Mid-Latitudes
TL;DR: In this article, the authors analyzed daily fields of 500-hPa heights from the National Centers for Environmental Prediction Reanalysis over N. America and the N. Atlantic to assess changes in north-south (Rossby) wave characteristics associated with Arctic amplification and the relaxation of poleward thickness gradients.

Changing state of Arctic sea ice across all seasons
TL;DR: In this paper, the authors examined the ongoing loss of Arctic sea ice across all seasons and found that recent anomalies in spring and winter sea ice coverage have been more significant than any observed drop in summer sea ice extent.
Journal ArticleDOI
The influence of Arctic amplification on mid-latitude summer circulation
TL;DR: It is shown that interactions between Arctic teleconnections and other remote and regional feedback processes could lead to more persistent hot-dry extremes in the mid-latitudes.

Flexible Electronics: Stretchable Electrodes and Their Future
TL;DR: In this paper, a review of the latest advances in stretchable transparent electrodes based on a new design strategy known as kirigami (the art of paper cutting) is presented.
Journal ArticleDOI
Evidence for a wavier jet stream in response to rapid Arctic warming
TL;DR: In this article, the authors find robust relationships among seasonal and regional patterns of weaker poleward thickness gradients, weaker zonal upper-level winds, and a more meridional flow direction.

TL;DR: ERA-Interim as discussed by the authors is the latest global atmospheric reanalysis produced by the European Centre for Medium-Range Weather Forecasts (ECMWF), which will extend back to the early part of the twentieth century.

TL;DR: HadISST1 as mentioned in this paper replaces the global sea ice and sea surface temperature (GISST) data sets and is a unique combination of monthly globally complete fields of SST and sea ice concentration on a 1° latitude-longitude grid from 1871.

TL;DR: The Community Earth System Model (CESM) as discussed by the authors is a community tool used to investigate a diverse set of Earth system interactions across multiple time and space scales, including biogeochemical cycles, a variety of atmospheric chemistry options, the Greenland Ice Sheet, and an atmosphere that extends to the lower thermosphere.

The central role of diminishing sea ice in recent Arctic temperature amplification.

TL;DR: It is shown that the Arctic warming is strongest at the surface during most of the year and is primarily consistent with reductions in sea ice cover, and suggests that strong positive ice–temperature feedbacks have emerged in the Arctic, increasing the chances of further rapid warming and sea ice loss.

Stratospheric harbingers of anomalous weather regimes.
TL;DR: Observations show that large variations in the strength of the stratospheric circulation, appearing first above ∼50 kilometers, descend to the lowermost stratosphere and are followed by anomalous tropospheric weather regimes, which precede shifts in the probability distributions of extreme values of the Arctic and North Atlantic Oscillations and the location of storm tracks.
