Sažetak
The dataset is the 40-year record (1958-98) of NCEP/NCAR re-analyses for sea surface temperatures and upper air fields, while, for snow depth fields, the Historical Soviet Daily Snow Depth dataset (based on observations at a series of 284 World Meteorological Organization (WMO) stations throughout the Former Soviet Union) is used. First the leading variability patterns of the atmospheric flow are searched for by calculating empirical orthogonal functions (EOFs) of seasonal anomalies. The Eurasian snow depth anomalies and SST anomalies associated with the leading circulation patterns are then identified by computing, for each season, the covariance between the principal components (associated with the EOFs) and the snow/SST anomaly time series. The relationship with the large scale monsoon circulation is evaluated through (lagged) correlations with the Webster and Yang index.
