Glad to see a centralized discussion on this topic here in the US. I have been following an European  blog called 'Severe Weather Europe' which discusses the polar vortex too. 

So to my question above - is there a corresponding 'vortex' over the South Pole?

If we are to examine the impacts of 'warming' and other human induced weather related changes isnt it necessary to examine impacts at both poles?

I came to this blog because of a 'shout out' about it from Dr. Swain at WeatherWest.
