Climate Prediction Center (CPC) Scandinavia Teleconnection Pattern Index

Monthly tabulated index of the Scandinavia teleconnection pattern. The data spans the period 1950 to present. The index is derived from a rotated principal component analysis (RPCA) of normalized 500-hPa height anomalies from the period 1950-2000. The data source is the NCEP/NCAR Reanalysis. The resulting time series is then re-normalized to coincide with the 1981-2010 base period monthly means. The index is updated monthly. Calculating the index using the RPCA approach is a somewhat complicated process, in that it is not derived independently of the other extratropical teleconnection pattern indices.
