An unusually early polar-vortex disruption could make weather history and influence winter conditions across the Northern ...

High above the North Pole, in a slice of atmosphere rarely noticed and even less understood, a transformation is underway. Over the next 10 days, changes in the stratosphere will upend weather ...

Will the Pacific jet stream or the polar vortex dominate November's weather? A 'blowtorch pattern' sets up, but for how long? We look at the deciding factors.

Have you ever wondered how something as simple as air can turn into something as powerful as a tornado? In this segment of Up and Atom, meteorologists Kellie McGlynn and Amanda Verrier show us a fun ...

The vortex is strongest during the winter and usually weakens or even disappears in the summer. When the polar vortex weakens or even splits, it allows frigid air to escape and push southward toward ...

Air cannons produce visible vortex rings by generating rotating air pressure differences, while electromagnetic cannons emit electromagnetic vortex pulses using coaxial horn antennas. The ...

Vortex rings, a mysterious and fascinating natural phenomenon, display breathtaking structures and behaviors in both air and electromagnetic waves. Imagine an air cannon that can shoot vortex rings, ...

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 ...
