Lagged relationships between North American snow mass and atmospheric teleconnection indices
Abstract Relationships between North American winter (January, February, March or JFM) snow mass, or snow water equivalent (SWE), between 1980 and 1997, and four teleconnection indices are explored at different spatial and temporal scales, with teleconnection indices leading SWE by one to two season...
