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

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

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 "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 ...

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.

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 ...

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 ...

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.
