| 1430519 | 2017-01-07 20:47:00 | Does anyone see a specific pattern here: 7796 When the Arctic vortex is at it strongest, there is a single vortex, but normally, the Arctic vortex is elongated in shape, with two cyclone centers, one over Baffin Island in Canada and the other over northeast Siberia. When the Arctic pattern is at its weakest, subtropic air masses can intrude poleward causing the Arctic air masses to move equatorward, as during the Winter 1985 Arctic outbreak.[14] The Antarctic polar vortex is more pronounced and persistent than the Arctic one. In the Arctic the distribution of land masses at high latitudes in the Northern Hemisphere gives rise to Rossby waves which contribute to the breakdown of the polar vortex, whereas in the Southern Hemisphere the vortex is less disturbed. The breakdown of the polar vortex is an extreme event known as a sudden stratospheric warming, here the vortex completely breaks down and an associated warming of 30–50 °C (54–90 °F) over a few days can occur. The waxing and waning of the polar vortex is driven by the movement of mass and the transfer of heat in the polar region. In the autumn, the circumpolar winds increase in speed and the polar vortex rises into the stratosphere. The result is the polar air forms a coherent rotating air mass: the polar vortex. As winter approaches, the vortex core cools, the winds decrease, and the vortex energy declines. Once late winter and early spring approach the vortex is at its weakest. As a result, during late winter, large fragments of the vortex air can be diverted into lower latitudes by stronger weather systems intruding from those latitudes. In the lowest level of the stratosphere, strong potential vorticity gradients remain, and the majority of that air remains confined within the polar air mass into December in the Southern Hemisphere and April in the Northern Hemisphere, well after the breakup of the vortex in the mid-stratosphere.[15] It's youse guyses turn to speak.............. |

| 1430520 | 2017-01-08 07:53:00 | The answer is HERE (www.youtube.com) somewhere Joe. Personally, I think a “Vortex Tax” should be introduced to offset the spiralling Polar Bear population. |

| 1430522 | 2017-01-08 19:53:00 | Well - I wasn't going there - not in an argument about global warming yea or nay. I was looking at the pattern and seeing that it seems to mostly be hovering over large land masses except where it incidentally also covers smaller seas and bodies of water to get over those large land masses. Any thoughts about that? |

| 1430524 | 2017-01-08 21:11:00 | I was under the impression that all planets have polar vortexes of some sort, at both poles, if a gaseous atmosphere is present in any substantial form so not sure what you are getting at here Joe. The North Pole Vortex is swinging it's lobes far further out and more erratically than we are used to normally seeing in the past 10 years or so, I don't need to say the phrase do I? Hint A.G.W. Anyway here is a far more interesting polar vortex on Saturn: en.wikipedia.org |

Must be somewhat balmy, perhaps the pictures of polar bears, on sun-loungers, sipping margaritas, etc may be prophetic? |

That's because the weather which should be in the North Pole and surroundings has moved to parts of Europe and America/Canada, Joe's vortex being responsible: www.independent.co.uk |

| 1430527 | 2017-01-08 21:44:00 | OK - I see that this is falling off the tracks. MY thought was that the Vortex is ONLY hovering over land masses and NOT over the waters of the world.... mostly so anyway. There's speculation that with the El Nino - or is it La Nina this time 'round - that the vortex phenoms (N & S Pole-wise) are not cooling the oceans - hence the idea that there's a new dynamic at work here. No? ..... and it's NOT my personal vortex. I know that Montana has had record cold here and I blame it on Upsidedown Land's Above Ground Nuclear Testing. |

I don’t think we will have to relocate the Polar Bears to the South Pole just yet Dave as it’s still -26ºC up there and within expetations. 7798 But the bit that gets me is it costs the American Taxpayer $4.7 Billion Dollars a year to fund this Pseudo-science, when I could have jacked them up a Tarot Card reader for a fraction of the cost. :crying Life can be so cruel. :) |
