"Bulge" in Atmospheric Pressure Responsible for Cold Winter Amid Global

The cold in places like Florida actually could be a sign of warming,
rather than an argument against the phenomenon

http://www.scientificamerican.com/article.cfm?id=bulge-in-atmospheric....

"The ongoing disappearance of sea ice in the Arctic from elevated
temperatures is a factor to changes in atmospheric pressure that control
jet streams of air, explained James Overland, an oceanographer of the
National Oceanic and Atmospheric Administration, or NOAA. That is
because ice-less ocean is darker and, thus, absorbs more solar heat,
which in turn spews warmer air than average back into the Arctic atmosphere.

"That unusually warm air can contribute to a "bulge" effect to the
atmospheric pressure controlling how cold air flows, according to
Overland, who works at NOAA's Pacific Marine Environmental Laboratory.
Rather than moving circularly in the Arctic from west to east as
typical, the bulge may prompt air to move in a U-shaped pattern down to
the southern United States".

Let's see if I can follow this logic...

The pole is warming so that pushes cold air south.

OK, it the pole is warming, where does the cold air come from?

And the "U-shaped pattern" doesn't have anything to do with the low
pressure area that usually forms in the Great Lakes area?

For the uninitiated, FL480 means 48,000 feet, and once you get above about
10,000 feet the general directions of the winds don't change much, just
the velocity and temperatures.

It's just not worth even trying to explain synoptics to these people.
