Snow coverage across the Northern Hemisphere has reached its highest extent for this time of year (mid February) in two decades, according to recent data.
The increase is primarily driven by substantial snowfall in Asia and North America, while Europe remains below average.
Satellite observations and meteorological reports confirm that snow extent has surged due to a combination of strong winter storms and persistent cold air masses, particularly across Siberia, Mongolia, Canada, and the northern United States. The spike in snowfall is linked to shifting atmospheric patterns, including a stronger-than-usual polar vortex and La Niña influences that have intensified winter weather in certain regions.
In Asia, heavy snow has blanketed vast areas of Russia, China, and Mongolia, with some regions reporting record-breaking accumulations. In North America, significant snowfall across Canada and parts of the northern United States has also contributed to the overall increase. Cities such as Chicago and Toronto have experienced heavier-than-average snowfalls, disrupting travel but boosting seasonal activities like skiing and snowboarding.
In contrast, Europe has seen below-average snow cover, particularly in western and central regions. Warmer-than-usual temperatures have limited snowfall in parts of Germany, France, and the United Kingdom, where rain has been more common than snow. Some Alpine regions, however, have still received substantial snowfall, though not enough to offset the overall deficit across the continent.
Experts suggest that while natural climate variability plays a role, the distribution of snowfall aligns with broader meteorological patterns influenced by global climate shifts. “We’re seeing strong regional differences in snowfall this winter, which are likely tied to changes in atmospheric circulation,” said Dr. Emily Carter, a climatologist at the Global Weather Institute. “While some areas are experiencing exceptional snow accumulation, others are dealing with warmer and drier conditions.”
The 20-year high in snow extent raises questions about long-term climate trends, but scientists highlight that such variations are influenced by multiple factors, including seasonal weather patterns, ocean currents, and Arctic conditions.
