Influence of EL Nino Southern Oscillation on Lake Effect Snow in Western New York

The El Nino Southern Oscillation (ENSO) is a global coupled ocean atmospheric phenomenon. Previous work has associated this atmospheric phenomenon with the disruption of global scale circulation patterns. Previous studies have focused on the disruption of the precipitation patterns. These can cause variability in weather patterns around the world, including, presumably Western New York. It is unclear if these disruptions will impact the coupled small scale system of atmospheric and lake interactions that cause Lake Effect Snow Storms. This study examines the influence of the ENSO phenomena by comparing Lake Effect Snow events for Buffalo, Rochester, and Syracuse to corresponding ENSO phases. First using upper air data, the influence of Synoptic Scale systems were removed from the precipitation record. Using simple statistics tests to compare the sample characteristics of El Nino, La Nina and Neutral phases of ENSO are statistically different from one another.
