On the seasonal time scale, the winter AO is found to be significantly correlated with the preceding autumn Eurasian snow cover (SNC EUR ) throughout the period observed.

However, starting in the mid 1980s, the AO and SNC EUR vary in phase. Analyses of the seasonal relationship and persistence of snow and atmospheric variables illustrate a phase shift in the sub-decadal variability between the AO and SNC EUR due to the loss of autumn-winter SNC EUR autocorrelation replaced by a significant winter-spring persistence and the emergence of a concurrent SNC EUR -AO connection in winter and spring. Similar analysis shows that the sub-decadal NAO variation is mostly described by the fluctuation in summer North American snow cover.
