Iarna ar putea avea două fețe în Europa: vortex puternic la început și schimbare majoră din ianuarie

The polar vortex is starting the winter season stronger than last year, but forecasts suggest a potential weakening in mid-winter, which could lead to cold and snow in Europe. The vortex has already formed over the Arctic, with a significant cooling of the stratosphere. While a strong polar vortex keeps cold air near the North Pole, a weakening could allow cold air to move southward. Seasonal forecasts indicate a possible weakening in January and February 2027, with models suggesting changes in stratospheric winds. Additionally, the ongoing Super El Niño may influence the vortex's stability. Meteorologists will monitor the situation closely, as a weakened vortex could lead to colder temperatures and snowfall in Europe later in the winter.
