## Key points

- The polar vortex has weakened and reversed unusually early.
- The disruption could raise the risk of cold outbreaks.
- Its effect on winter weather remains uncertain.

## Summary

Scientists have recorded an unusually early disruption of the polar vortex, a ring of cold air high above the Arctic, with its winds weakening and reversing direction. The event may increase the chance of cold air reaching parts of the Northern Hemisphere, but it does not mean a severe winter is certain.

The vortex sits about 10 to 50 kilometres above Earth and is linked to the jet stream, which helps shape weather at the surface. Disruptions can take weeks to recover from; a previous one contributed to the 2021 Texas freeze. Forecasters say other patterns, including a strengthening El Niño, could affect the outcome, and the precise impact remains unclear.
