Blame The Jet Stream On Colder Winters

Here on the East Coast of the U.S., winter has not been kind to us this year. Researchers say they know why. A new study from Rutgers University indicates that the unusually chilly temperatures in the Midwest and southeastern US are due to a slowing in the high-altitude polar jet stream which is driving cold polar air to the south. But why? You probably guessed it – climate change. Researchers said that the warming of Arctic air now means there is less of a temperature difference when polar air hits air from lower latitudes. They say the jet stream is driven by the temperature contrast and since now there’s not much of a “contrast,” weather patterns are changing. Researchers continued by saying “we can expect more of the same and we can expect it to happen more frequently.”
