JERUSALEM, July 11 (Xinhua) -- An international research group has found that extreme cold snaps in the United States are driven by disruptions in a high-altitude Arctic air mass called the polar ...

While this polar vortex event will not affect Northern California, its presence in the central and eastern U.S. will have an impact on the weather pattern for the West Coast.

The polar vortex is area of fast-moving winds well above the Earth’s surface and the jet stream that circle the Arctic during the Northern Hemisphere’s coldest months.

The United States has been at the epicenter of the planet’s most unusually cold conditions early in 2025. The polar vortex is to blame.
