I don't think I have ever shared this uncropped original photograph before. Low resolution but still effective. I like how the tail curls around the girder.

Polar bag of wind

Northern jet stream 1/6/14
RUSH: So, ladies and gentlemen, we are having a record-breaking cold snap in many parts of the country. And right on schedule the media have to come up with a way to make it sound like it's completely unprecedented. Because they've got to find a way to attach this to the global warming agenda, and they have. It's called the "polar vortex." The dreaded polar vortex.
Do you know what the polar vortex is? Have you ever heard of it? Well, they just created it for this week. Actually, there is a piece. I've got a piece in the Stack that actually makes the case that all of this frigid, chilling cold is due to global warming, strange as it may sound, it says. Other wackos are saying it's a great example of climate change, but regardless, the agenda is that we're responsible, we're causing it, we have to pay the price. And so any weather extreme now is said to be man-made, and therefore it fulfills the leftist agenda on this.
Now, in their attempt, the left, the media, everybody, to come up with a way to make this sound like it's something new and completely unprecedented, they've come up with this phrase called the "polar vortex." If you've been watching television, they've created a graphic, all the networks have, and it basically consists of a view of the planet if you are right above the North Pole. They put this big purple blob, or blue blob, or red blob, depending on the network you're looking at, over the entire North Pole, and they call that the polar vortex. It actually sounds like a crappy science fiction movie to me, but anyway, that's what they're calling it. It makes it sound like the jet stream is being forced lower across the United States.
Limbaugh says that the polar vortex is a new political invention. He's, of course, wrong. I started studying it, saw citations going back to 2001, have heard about it being discussed back in 1991. There are a ton of scientific papers extant regarding the phenomenon. Saturn has a hot polar vortex and I don't believe that they are yet a part of the great liberal conspiracy.
A polar vortex (also known as an Arctic cyclone, sub-polar cyclone, Frigid Twister, and a circumpolar whirl) is a persistent, large-scale cyclone located near either of a planet's geographical poles. On Earth, the polar vortices are located in the middle and upper troposphere and the stratosphere. They surround the polar highs and lie in the wake of the polar front. These cold-core low-pressure areas strengthen in the winter and weaken in the summer.[1] They usually span 1,000–2,000 kilometers (620–1,240 miles) in which the air is circulating in a counter-clockwise fashion (in the northern hemisphere). As with other cyclones, their rotation is caused by the Coriolis effect.The Arctic vortex in the Northern Hemisphere has two centres, one near Baffin Island and the other over northeast Siberia.[2] In the southern hemisphere, it tends to be located near the edge of the Ross ice shelf near 160 west longitude.[3] When the polar vortex is strong, the Westerlies increase in strength. When the polar cyclone is weak, the general flow pattern across mid-latitudes buckles and significant cold outbreaks occur.[4] Ozone depletion occurs within the polar vortex, particularly over the Southern Hemisphere, which reaches a maximum in the spring.
Studies published since 2001 suggest a link between extreme weather and the polar vortex, in recent years more research identified interactions with Arctic sea ice decline, reduced snow cover, evapotranspiration patterns, NAO anomalies or weather anomalies which are linked to the polar vortex and jet stream configuration.[12][13][14][15][16][17][18][19] However, because these are considered short-term observations (since ~13 years) there is considerable uncertainty in the conclusions. Climatology observations require several decades to distinguish natural variability from climate trends.
The general assumption is that reduced snow cover and sea ice reflect less sunlight and therefore evaporation and transpiration increases, which in turn alters the pressure and temperature gradient of the polar vortex, causing it to weaken or collapse. This becomes apparent when the jet stream amplitude increases (meanders) over the northern hemisphere, causing Rossby waves to propagate farther to the south or north, which in turn transports warmer air to the north pole and polar air into lower latitudes. The jet stream amplitude increases with a weaker polar vortex, hence increases the chance for weather systems to become blocked. A recent blocking event emerged when a high-pressure over Greenland steered Hurricane Sandy into the New Jersey coast and the New York metropolitan area.[20]
You wonder how a venomous buffoon like El Rushbo doesn't get his porcine balloon popped when he engages in these kinds of inventions and falsehoods. Then he runs to the you caught me, I was only kidding card, can't you liberals take a joke? The problem is how easy it is for him to hornswaggle the average Fox/Limbaugh listener.

I was reading today's transcript and he came up with this one. Can he really be this stupid or is he merely relying on the stupidity of others?
There are two rescue ships stuck in the ice in Antarctica. Why don't they ever try to get the jet stream to come from the South Pole? You know, it's summer down there now. Why not get the jet stream down there to counter the jet stream from the North Pole. I mean, if we're doing something to cause the jet stream to slow down, let's speed the one up from Antarctica.

Check out my flatulence vortex. Care to light one up?
