High-latitude snowfall as a sensitive indicator of climate warming: A case study of Heilongjiang Province, China

While global distribution and dynamics of snow extent and snow depth have been intensely studied, the response of snowfall events to global warming is complex and remains unclear in current literature. This study explores historical snowfall records since the 1960s at 62 meteorological stations in H...
