Changing Nature of High‐Impact Snowfall Events in Eastern North America Journal of Geophysical Research: Atmospheres

Snowstorms cause substantial disruption in the eastern United States and Canada each winter. While reductions in annual snowfall are projected over most of this region due to anthropogenic global warming, daily snowfall extremes that have the greatest impact may not decrease in the same manner. We examine changes to two extreme snowfall metrics: the 95th percentile of daily snowfall (SF95, cm) and the number of events during which 10% of the mean annual snowfall is exceeded during a single day (TC10, events yr −1). We explore changes to these metrics in two ensembles of the fifth-generation Canadian Regional Climate Model, including four 0.22° (≈25 km) simulations driven by different coupled general circulation models
