When the polar vortex stretches, North America feels the chill. New research reveals some of the stratospheric patterns ...
Dramatic waves in the jet stream can also usher south the polar vortex, which is the raft of subzero air circling the North Pole that has become a popular term for bouts of dangerously cold ...
A. One of the main factors for a weather event like this is the position of the jet stream, what we call “the polar front jet stream.” In the upper atmosphere, about 50,000 or 60,000 feet from the ...

Images sent back to Earth revealed that Jupiter’s north pole has a central vortex that’s about 3,000 miles across, ringed by eight other vortices of about the same size.
The Associated Press The term “polar vortex” usually refers to the gigantic circular upper air weather pattern in the Arctic region. It is a normal pattern that is stronger in the winter and keeps ...
What is the polar vortex? The polar vortex is a part of Earth's atmosphere that is found over the North Pole.
“The polar vortex has been particularly strong and stable the past few weeks. That has kept the coldest of Arctic air largely confined to the North Pole,” says Mike Bettes, meteorologist with ...
That uncertainty means it’s also unclear whether polar vortex stretching actually leads to, or is just a result of, the tropospheric conditions that drive cold air outbreaks over North America.
The polar vortex has taken on an unexpected pattern this winter - one that’s made part of the United States the most unusually cold place on the planet, at least so far this year. While the ...
The sudden winter chill came thanks to the polar vortex, an area of low pressure and cold air in the Arctic near the North Pole, that has taken hold over parts of the country, meteorologists say.
