  "account": "Meteorologists reported on Friday an unprecedented early disruption of the polar vortex, a region of cold air high above the Arctic, raising the risk of cold snaps across the Northern Hemisphere. This is the earliest stratospheric vortex disruption observed, according to scientists from the European Centre for Medium-Range Weather Forecast (ECMWF). The disruption could be attributed to a strong El Niño event in the Pacific or a high-pressure system over Scandinavia, though the exact cause remains uncertain. The polar vortex typically strengthens through autumn and peaks in January, but it can weaken between January and March, allowing cold air to spill south into Europe, North America, and Asia. The disruption, if it persists, could increase the likelihood of cold air outbreaks in densely populated regions, though the severity of any cold spells remains uncertain.",
