"The strength of the jet stream is directly proportional to the difference in temperature between the poles and the tropics. When it's strong, the jet stream tends to take a straighter path, but when it's weak it meanders. As the Arctic is experiencing warming at faster rates than the tropics, that difference is getting smaller, so the jet stream is weakening along with it."

"Mark Serreze, the director of the U.S. National Snow and Ice Data Center, was on the panel along with Francis. He says the idea that changes in the polar north could influence mid-latitude weather, was a new and lively area of research.

"Fundamentally, the strong warming that might drive this is tied in with the loss of sea-ice cover that we're seeing, because the sea-ice cover acts as this lid that separates the ocean from a colder atmosphere," Serreze says.

"If we remove that lid, we pump all this heat up into the atmosphere. That is a good part of the signal of warming that we're now seeing, and that could be driving some of these changes.""

Shouldn't global warming make the tropics warmer?

What's the "jet stream" compared to Mammade global warming? You Deniers make me laugh

With any luck Chicago will break the record.

It has. It's just had a greater effect on the Arctic. Surely you've heard this before. The temperature increase in the Arctic is greater than anywhere else on the planet. So the delta has been decreased.

If the jet stream "got weaker" than that's great news for Tornado Alley. And the intensity of storms over the CONUS should be lessened.

I'm not inclined to watch an hour and a half video, but the paper I led this thread with contends that the increased temperatures in the Arctic have caused the development of Rossby waves in the Jet Stream which are responsible for the large amount of Arctic air and snow coming through the US midwest and northeast.

C'mon. Let's get this straight. IT'S ALL PRESIDENT BUSH'S FAULT!!!

 

[Abraham3]

Given his utter failure to do anything in response to global warming, you could say that if you wanted to. But it doesn't help.

Dr. Jennifer Francis is a Phd Meteorologist from Rutgers, and explores the whole connection of Arctic Ice and the Jet Stream in this lecture.

What I find bizarre is what bad weather superimposed over voting patterns seems to show. Including CA where are the threads about God's wrath?

 

[Kosh]

Once again the AGW cult has no clue on what they have posted other than it had one of seven key words.

Another failed thread from the AGW cult.

The belief in the AGW religion is strong, so no amount of science will defeat the church dogma.

The desperation is amusing to say the least! Here's the best information on the Jet Stream and what causes it to behave in this manner. Please note, that unlike your cute little "study" that has no observational support, THIS study does....




"New Scientist, April 14, 2010



Brace yourself for more winters like the last one, northern Europe. Freezing conditions could become more likely: winter temperatures may even plummet to depths last seen at the end of the 17th century, a time known as the Little Ice Age. That's the message from a new study that identifies a compelling link between solar activity and winter temperatures in northern Europe.



The research finds that low solar activity promotes the formation of giant kinks in the jet stream. These kinks can block warm westerly winds from reaching Europe, while allowing in winds from Arctic Siberia. When this happens in winter, northern Europe freezes, even though other, comparable regions of the globe may be experiencing unusually mild conditions.



Mike Lockwood at the University of Reading in the UK began his investigation because these past two relatively cold British winters coincided with a lapse in the sun's activity more profound than anything seen for a century. For most of 2008-9, sunspots virtually disappeared from the sun's surface and the buffeting of Earth by the solar magnetic field dropped to record lows since measurements began, about 150 years ago.



Lockwood and his colleagues took average winter temperatures from the Central England Temperature dataset, which extends back to 1659, and compared it with records of highs and lows in solar activity. They found that during years of low solar activity, winters in the UK were far more likely to be colder than average. "There is less than a 1 per cent probability that the result was obtained by chance," says Lockwood, in a paper to appear in Environmental Research Letters."

So global warming makes winters colder?

You're serious about this theory?

Remember when all the AGW nutburgers were saying that global warming meant there would be no more snow?.
