Space exploration missions have revealed that polar vortices aren’t uncommon beyond Earth. They’ve been observed throughout ...

A "major disruption" has recently rocked the Arctic polar vortex, causing it to weaken and reverse direction from west-to-east to east-to-west. Amid the chaos, the vortex shifted off the pole and ...

Several days with temperatures of 10-20 degrees below the historical average could be dangerous to plants and ruin outdoor ...

The Polar Vortex in the upper atmosphere has disintegrated after the intense warming of the stratosphere in mid-March.

Brrr, January 2025 is bringing some serious chill! 🥶 Dive into the science of the polar vortex and learn what’s behind this ...

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.

When the AO turns toward a negative phase, however, it means that the polar vortex is weaker than normal. This can force that circulation of winds to become unstable and wavy, often sending frigid ...

Such cold air blasts have become known as the polar vortex. It’s a long-established ... Northwest to the Southeast and is stuck on that wavy track. To the west of that plunge, in California ...

a wavy jet stream can mean the difference between a mild winter day and a bone-chilling freeze. Understanding these dynamics is crucial for predicting and preparing for the polar vortex's icy grip.

For instance, a wavy jet stream was partly responsible for the infamous “polar vortex” that brought freezing temperatures to North America in recent years. It’s a bit like a traffic jam in ...

Researchers from the University of Leeds have found there was an extremely strong stratospheric polar vortex (SPV) – a large spinning mass of cold air in the stratosphere around 15 miles above ...
