    Yes, that is consistent with most studies to date. Records indicated that winter has been shrinking in duration at both ends, but the core of winter is not warming. There is evidence to suggest that snowfall may even be increasing, though a lack of a consistent snowfall record complicates this conclusion. All of this is consistent with a warming global climate, especially in the Arctic. The hypothesized connection is that a warmer Arctic Ocean is leading a less stable polar vortex. When the polar vortex splits you get rapid, dramatic warming in the Arctric and a cold air outbreak to mid-latitudes. New England is one of the favored locations of these outbreaks due to a coincidence of geography.

    Awesome info Yeggous.

    I am so sick of the media buzz words. They make it sound like a polar vortex has never happened before. IT is called a f'in artic low with a high pressure ridge blocking it.

    Without the buzz word it would be commonly known as "that time it was really fucking cold for a month"

    It's true that the media has perverted the term polar vortex, but it is a real thing. It's not an arctic low. Those (a.k.a., polar lows) are essentially hurricanes where it is really cold. Thermodynamically there is practically no difference between a tropical hurricane / typhoon / cyclone, and and a polar low.

    A polar vortex split differs from a typical cold air outbreak in its dynamics. The polar vortex has a deep coupling all the way up into the stratosphere. It should up very clearly on a potential vorticity map. Where the vortex become distorted due to wave disturbances around its periphery, this is your typical cold air outbreak while the center of the vortex remains centered in the arctic. What we're talking about is a vortex breakup / split where you end up with two (or sometimes more) distinct vortex centers which typically wander more equatorward over the continents. This vortex split is associated with a "sudden stratospheric warming".

    For extra credit, the sudden stratosphere warming is caused by breaking a planetary-scale waves called Rossby waves. These waves are observable and forecastable well in advance due to their large scale. When we forecast a polar vortex split so far in advance, it is usually because we can see a large Rossby wave breaking event coming and know what comes next. The dynamics of Rossby wave are complicated "and will be left for the reader", but involve the rotational forces of the Earth.

    The real question

    Patterns shifting?

    I find this interesting.

    A polar low is a small-scale, short-lived atmospheric low pressure system (depression) that is found over the ocean areas poleward of the main polar front in both the Northern and Southern Hemispheres.

    A polar vortex is a large pocket of very cold air, typically the coldest air in the Northern Hemisphere, which sits over the polar region during the winter season.

    I also find this interesting too!

    Those questions are impossible to answer.
