Arctic Ice Melt May Shift Jet Stream South, Cause Rainy UK Summer

Nature World: A new study published in the journal Environmental Research Letters suggests that a loss of Arctic sea ice caused the jet stream to shift further south, thus contributing to an extraordinary run of wet summers experienced by Britain and northwest Europe between 2007 and 2012. University of Exeter scientist James Screen uses a computer model to investigate the wet weather and whether it was linked to the melting of sea ice in the Arctic. Screen's study "compared weather patterns during low sea...
Wacky jet stream blame for wild North American weather
2013-09-25 20:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: A lot of wild weather has afflicted North America this year: deluges in Colorado and Alberta, a heatwave in Alaska, and bitter cold in Florida. But there`s a high-altitude link between each of these unusual events which itself might be tied to climate change: erratic behavior by the polar jet stream. This famous current of air zips eastward at high altitudes from the continent`s West, normally passing over North America somewhere near Seattle. It is one of two jet streams in the Northern Hemisphere...

Wild Weather Tied To Unusual Jet Stream Activity
2013-09-25 09:43:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: There has been a lot of extreme weather in the Northern Hemisphere this year, including the recent torrential rains in Colorado, flooding in Europe, bitter cold in Florida and a heat wave in Alaska. And scientists say all of it is related to some odd behavior by the powerful air currents called the polar jet stream. The jet stream is "this ribbon of very fast moving winds that's high over our heads," says Jennifer Francis, a research scientist at the Institute of Marine & Coastal Sciences at Rutgers...

Scientists say jet stream causing weather whiplash as it wobbles
2013-07-21 17:09:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The jet stream - the river of air high above Earth that generally dictates the weather - usually rushes rapidly from west to east in a mostly straight direction. But lately it seems to be wobbling and weaving like a drunken driver, wreaking havoc as it goes. The more the jet stream undulates north and south, the more changeable and extreme the weather. The most recent example occurred in mid-June when some towns in Alaska hit record highs. McGrath, Alaska, recorded an all-time high of 94...
