The Influence of Regional Storm Tracking and Teleconnections on Winter Precipitation in the Northeastern United States

摘要: Abstract Secular changes in regional storm tracking are examined as physical mechanisms for observed teleconnections between the New England hydroclimate and four predictor variables: Southern Oscillation Index, North Atlantic Oscillation, Pacific Decadal sea-surface temperatures. The main modes of winter precipitation, snowfall, cyclone variability resolved using varimax rotated principal component analysis. first defines an out-of-phase relationship marine versus continental activity is statistically linked with precipitation northern England. Also, El Nino winters generally accompany a slight increase southern precipitation. second component, defining inverse occurrences along East Coast alo...
