The influence of the North Atlantic oscillation on seasonal snowfall totals in the northeastern United States, 1961-2010
The North Atlantic Oscillation (NAO) is one of the main components of atmospheric circulation variability within the middle and high latitudes of the Northern Hemisphere and largely affects winter weather in northeastern United States. This study examined the most recent decadal trend of the NAO as...
