Pattern Calculation Procedures: Description of Rotated Principle Component Analysis (RPCA) technique used to identify teleconnection patterns.

Index Calculation Procedures: Description of RPCA technique used to calculate monthly teleconnection indices.

Explained Variance time series showing monthly total explained variance by the ten leading teleconnections patterns.

Individual teleconnection patterns: Discussion, Height Anomaly Map, and plotted historical Time series for the period January 1950-March 1997

Historical Archive of all Indices: Monthly Tabulated Indices for all teleconnection pattern amplitudes dating back to 1950. Indices are standardized by the 1981-2010 climatology.

Recent Monthly Time series: Time series of pattern amplitudes for the last few years for selected teleconnection patterns, from the Climate Diagnostics Bulletin.
