The ECMWF model predicts a significant disruption of the polar vortex in early November, potentially splitting it into two. This could alter atmospheric circulation in the Northern Hemisphere and affect cold air penetration in the coming weeks. However, it does not guarantee a harsh winter for Europe or North America. The forecast is also linked to the ongoing El Niño phenomenon, which influences global atmospheric circulation but does not directly dictate regional weather. A sudden stratospheric warming could lead to changes in weather patterns, but the effects may not be immediate. Even during a strong El Niño, cold air outbreaks and severe winter storms remain possible, depending on various atmospheric factors.
