The polar vortex is essentially a large area of low pressure and cold air surrounding both of Earth’s poles. It constantly sits over the poles but expands in the winter.

The vortex is essentially an area of low pressure in the upper layers of the atmosphere over the polar region. This vortex consists of powerful westerly winds in the stratosphere, about 10 to 30 ...

“The polar vortex is a core of extremely cold air that typically remains near the poles,” explains Spectrum News NY 1’s Chief Meteorologist John Davitt.. “During the winter, shifts in the ...

These polar vortex stretches are happening more frequently as the world — and especially the Arctic — warms, a 2021 paper published in the journal Science, also co-authored by Cohen, demonstrated.

Because this is the Polar Vortex Blog, we would love to be able to tell you how the stratospheric polar vortex is doing super cool things that can explain how cold and snowy it’s been in many ...

The polar vortex spins anticlockwise around the North Pole with wind speeds of about 155mph (250km/h). There are two types of polar vortexes – tropospheric and stratospheric.

The polar vortex breaking off and sending cold air down south is not always an indicator of snow in North Carolina. If we look at the time frame for which we see that next Arctic blast, we'd be ...
