Eurasian Snow Cover Variability Links with Stratosphere-Troposphere Coupling and its Impacts on Alaskan Weather
Using both observational analysis and novel numerical modeling experiments, we showed that autumn snow cover extent and Arctic sea ice trends can force observed increasing trends in stratospheric polar vortex stretching and surface impacts. Our analysis provides a dynamical link between rapid Arctic change and extreme winter weather across large regions of the Northern Hemisphere.
