jimmy cee,

I suspect that the "powers that be" received so much input about that deceptive label that they simply pulled it.

The basic concept, as I understand it, has been around for decades.  However, it required a new label to tie it to the threat of globull warming.

A cold front is the weather system developed by the polar vortex presenting itself in the atmosphere or by other means ,

The cold front is found across a frontage or adjacent to an opposing type of weather .

 The term weather vortex  has been with us for years apparently , it is not a simple jet stream high in the atmosphere but a regular gently oscillating wide path travelling round the earth clockwise or anticlockwise  frequently visiting the sub Arctic or sub Antartic  depending which hemisphere it is in .

I think !   Laughing
 Now to Google it  What a Face .

 One thing for sure tonight 08 Jan 20115 it's colde nough to freeze th ....... well blow me down with a feather ..I've just seen a welder being chased by a brass monkey  Laughing Laughing

When forecasting winter, the term ‘polar vortex’ has been quoted a lot in recent years, but what is it, and how does it affect the weather we can expect?

Polar vortex
The polar vortex is an area of low pressure that spins above both the North and South Poles. It’s a circulation of air high up in the atmosphere at around 50km, much higher than the troposphere, where our ‘weather’ happens.
It’s always there, but tends to strengthen through the autumn in the northern hemisphere and weaken in the spring.
In the winter months the lack of sunlight over the Arctic means that cold air becomes established there, and, as it spins, the polar vortex keeps this cold air over the poles. This cold air is ‘fenced in’ by the polar jet stream.
What happens if the polar vortex breaks down?
Some theories suggest that a breakdown of the polar vortex can influence surface weather, leading to colder air coming down to lower levels.
This is because a breakdown in the polar vortex can lead to subsequent changes in the polar jet stream, which is the fast-moving ribbon of air which influences our weather patterns.
If the jet stream dives south in winter, it can bring cold air down over the UK from the poles.
Not all cold snaps are linked to the polar vortex, however. High and low pressure systems and the jet stream all have an effect on the air which heads to the UK over winter, and the direction of the air is crucial when it comes to helping to determine whether it will be bitterly cold or mild.
