英文摘要: Both observational and numerical studies suggest that fall snow cover extent over Eurasia is linked to subsequent winter variations in the predominant Northern Hemisphere teleconnection pattern, known as the Arctic Oscillation (AO). The present study uses the recent 20th Century Reanalysis to explore the snow-AO relationship over the entire 20th century for the first time. 20th Century Reanalysis is first shown to have a consistently realistic simulation of the onset of the Eurasian snow cover compared to a large number of in situ observations. It is then used to explore the snow-AO relationship over both the satellite and presatellite periods. Results show that this teleconnection is not stationary and did not emerge until the 1970s. The possible modulation of the teleconnection by the Quasi-Biennal Oscillation is then discussed, because it could have favored the influence of snow anomalies on the Arctic Oscillation in recent decades. These results have important implications for seasonal forecasting and suggest, in particular, that statistical predictions of the wintertime AO should not be based on snow predictors alone. © 2013.
