Un nou vortex polar se formează deasupra Polului Nord. Ce ar putea însemna pentru iarna 2026–2027

A new polar vortex is forming over the North Pole, potentially stronger than last year. Seasonal models suggest a weakening in January and February 2027, which could lead to cold spells and snow in parts of Europe, the US, and Canada. A strong vortex typically keeps cold air contained in the Arctic, resulting in milder winters in some regions. However, if the vortex weakens, cold air may move southward, increasing the likelihood of colder weather. The impact on Europe, including Romania, remains uncertain, with potential for cold air incursions but no guarantee of a harsh winter. Monitoring will continue as the season progresses.
