Ok, once more for the slow of thinking:
The polar jet stream is an effect of the temperature differential between the arctic and the temperate zones. A warmer arctic mean less temperature differential which in turns leads to a weaker polar jet. The weaker polar jet stream wanders more than a strong polar jet, allowing these polar vortex disruptions that bring arctic temperatures to portions of the US that don't normally see them.
This isn't brain surgery kids, it's an easily observable effect.
Yes it is... And you got it wrong. The stronger polar jet, as we see today, is being pushed out from tight constraint (where a weak polar jet would be kept) by the thinning atmosphere and cooling at high altitude. The temperature gradient widens in cooling causing larger lows and highs in the arctic. These are pushed southward by the thinning polar atmosphere and weakening equatorial jet.
Your totally upside down and inside out to the facts..
Lol, are you seriously just rejecting the facts and substituting your own made up crap?
Its called laughing like hell at people like you, who have no clue how the atmosphere works. That is what I am laughing at..
Tell me, Do you know the average wind speed and size of the polar jet during times of close to equilibrium? Do you understand that the polar jet of today is 2X bigger than it was just 14 years ago? You all have this misconception that we are still warming, we are not... But carry on, its fun to watch.
