Standardized amplitudes of selected Northern Hemisphere teleconnection patterns for the most recent thirteen months. Pattern names and abbreviations are: East Pacific pattern (EP); North Pacific pattern (NP); Pacific/ North American pattern (PNA); East Atlantic/ Western Russia pattern (EATL/ WRUS- called Eurasia-2 pattern by Barnston and Livezey, 1987, Mon. Wea. Rev., 6, 1083-1126); and Scandinavia pattern (SCAND- called Eurasia-1 pattern by Barnston and Livezey 1987). No value is plotted when a pattern does not appear as a leading mode in that month.
