On the association between Eurasian snow cover and North American winter temperatures
The extent of snow cover over Eurasia during autumn has proven influential in shaping atmospheric circulation over the Northern Hemisphere the following winter via the Arctic Oscillation (AO) and the Pacific/North American (PNA) teleconnections. Regions of active autumnal Eurasian snow cover were de...
