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.

A researcher expects the polar vortex to strengthen over the next two weeks. This has a big impact on our day-to-day weather here in the Great Lakes region and even the Northeast. Judah Cohen ...

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.

The polar vortex is like a giant, swirling pool of super-cold air in the upper atmosphere over the North Pole. Imagine it like a children's spinning top.

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 ...

A polar vortex could bring cold winds to much of the U.S. as the new year approaches—but what exactly is a polar vortex, and how could it affect the weather in 2025? Why It Matters.

Polar vortex headed for US will bring ‘exceptionally cold’ temps in the new year: ‘Weather models are screaming’ By . Alex Oliveira. Published Dec. 30, 2024, 8:14 p.m. ET.

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 is an expansive area of low pressure in the stratosphere, about 10 to 30 miles above the surface, which remains constant above the Earth’s Poles. according to Climate.gov.

During the polar vortex, temperatures could reach 12-25°F below average in some states, according to AccuWeather. “This could end up being the coldest January since 2011 for the U.S. as a whole ...

A polar vortex is set to bring weeks of icy temperatures to the Lower Hudson Valley and New York City. “This could end up being the coldest January since 2011 for the U.S. as a whole,” said ...
