Standardized amplitudes of selected Northern Hemisphere teleconnection patterns for the most recent thirteen months. Pattern names and abbreviations are: North Atlantic Oscillation (NAO); East Atlantic pattern (EA); East Atlantic Jet pattern (EA-JET); West Pacificn pattern (WP). No value is plotted when a pattern does not appear as a leading mode in that month.
