Description: North Atlantic Oscillation (NAO) index. Year is on the x-axis (1900–2005), and the standardised principal-component based winter NAO index on the y-axis. The bars show each winter's mean NAO index (where for instance "winter 1900" means the period from December 1899 up to and including March 1900). The black line is the 5-year running mean of the same index values (smoothed with a Gaussian filter).
