Capital Weather Gang Arctic warming, jet stream coupling may mean another winter of extreme storms and cold air outbreaks for eastern U.S. December 24, 2013 By Steve Tracton ...

The jet stream is a ribbon of high altitude, high-speed wind in northern latitudes that blows from west to east. It is formed when the cold Arctic air clashes with warmer air from further south.

“Our study shows that the changes in the jet stream are at least partly due to the loss of Arctic sea ice. If the ice cover continues to dwindle, we believe that both the frequency and intensity of ...

Blame jet stream, Arctic air for repeat snowstorms By Carolyn Y. Johnson Globe Staff,February 10, 2015, 6:38 p.m. 8 ...

An unusually wavy jet stream — a ribbon of fast-moving air that flows over the Northern Hemisphere — is to blame for an Arctic onslaught that is blasting most of the United States with snow ...

The jet stream flowing north through the 49th state pushes up into the Arctic, hits a wall of cold air, grabs some of that and ricochets south to bombard the East Coast of the U.S. with cold and snow.

Extreme cold weather being caused by the jet stream is not a result of Arctic warming, research suggests. Past studies have indicated the warming Arctic region causes a wavier jet stream – which ...

The “wavier” jet stream can lead to colder weather in the UK and the on continental Europe. But scientists now think the change in wind patterns is not caused by the Arctic.
