The Polar Vortex,an atmospheric phenomenon that shapes our winter weather,has been gaining attention as it undergoes changes ...

There are more ways than we knew for the stratospheric polar vortex to get disrupted, shooting cold air southwards across ...

Stratospheric polar vortex changes still trigger brutal U.S. winter cold snaps and extreme weather despite a warming climate.

The mechanism involves atmospheric waves that bounce between the upper atmosphere and ground level, amplifying weather patterns and making them more extreme. Scientists call this “stratospheric wave ...

Despite a warming climate, bone-chilling winter cold can grip parts of the U.S. In a study appearing in Science Advances, ...

Because of an unstable polar vortex, experts have projected record low levels of Arctic sea ice for the coming winter.

Three factors are combining to increase the likelihood of a weaker polar vortex this winter, the website reports. And a ...

Public perception to the contrary, outbreaks of the polar vortex in the northern hemisphere—the bitter cold triggered by the wandering jet stream—are becoming less common.

A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation shows the vortex also moved away from the Arctic towards Europe.

Powerful winter storms which led to deaths and power outages in the UK and Ireland were made more likely by an intense swirling vortex of winds miles above the Arctic, say scientists.

The development of tools that appropriately simulate electric-natural gas interdependencies and their resulting propagation of disturbances within and between systems is a particular need of system ...
