As Canadians, we are very familiar with the term ‘polar vortex.’ We are also familiar with its effects on Canadian weather when it ‘acts up.’ While the polar vortex is a year-round phenomenon, we tend ...

The polar vortex circling the Arctic is swirling in the wrong direction after surprise warming in Earth's atmosphere triggered a major reversal event earlier this month. It is one of the most extreme ...

Some of the coldest air in years is expected to plunge into the High Plains, Midwest and finally the East in the coming days as arctic air dips down into the Lower 48 for a spell. The mere mention of ...

Atmospheric scientists were surprised earlier this month to notice that the Arctic's polar vortex reversed its trajectory as it began spinning in the opposite direction. What's more: It has yet to ...

The polar vortex rages in the arctic during the winter, producing winds up to 150 miles per hour. But when that vortex weakens, arctic air escapes to more southerly latitudes, which creates ...

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, ...

The Arctic witnessed a meteorological phenomenon this month when a sudden stratospheric warming event compelled the polar vortex to deviate from its usual path, inverting its rotation. Instead of its ...

The polar vortex is a winter weather feature. At some point in spring or early summer, the polar vortex shrinks and disappears for the summer. The shrinking and disappearing of the polar vortex is ...

GRAND RAPIDS, Mich. — We saw young children at Plainfield Child Care in Grand Rapids, but they were amazed at some of the science and weather experiments we did. They all love talking about tornadoes, ...

A spinning fire vortex spotted on video Friday among the flames in a raging Pacific Palisades wildfire looks similar to a tornado, but scientists are still examining whether it was a rare fire tornado ...

Earlier this month, a sudden atmospheric warming event caused the Arctic's polar vortex to reverse its trajectory. The swirling ring of cold air is now spinning in the wrong direction, which has ...
