Weathermen have warned a frozen donut at the top of the world is set to unleash another cold snap.
The 3,000 mile-wide circle of winds – dubbed the ‘North Pole donut’ after Homer Simpson’s favourite snack – will bring chills and snow to Britain in weeks, boffins warn.
Cold air is set to seep south after the loop of polar vortex winds weakens this week, letting out bitter air trapped inside the Arctic Circle.

The Beast from the East in 2018 and the Big Freeze in 2010 were both caused by the same phenomenon.
Forecasters warn of snow flurries next weekend and beyond, with cold spells, freezing nights and frosts during February.
Met Office forecaster Alex Deakin said: “The doughnut of strong winds at the Pole is the polar vortex. And there’s a weakening of the Polar Vortex.”
The Met Office said: “Changes in the Polar Vortex can see a weaker jet stream, allowing more frequent cold air from the Arctic.”
The Weather Outlook forecaster Brian Gaze said: “A February cold spell would see -10C possible with snow risks. February has traditionally seen some of Britain’s coldest weather.”
BBC Weather said: “The potential for Arctic air is dependent on disruptions to the Polar Vortex, which looks distorted as January ends.
“Between frontal systems into February, we can expect wintry showers in northern areas.”
Met Office forecaster said: “Towards next weekend has the risk for wintry showers in the northeast, with the risk of frost following, especially in the South.
“February 11-25 has temperatures likely average or slightly above, with brief colder spells possible.”
This comes after snowfall and 60 mph winds were froecast this weekend for certain parts of the country.
A senior Met Office presenter said: "As we move through Sunday, winds will start to pick up, particularly across the north. Gusty conditions will develop across the Pennines in England."
