Reconstruction of the North Atlantic Oscillation, 1429–1983
Abstract The North Atlantic Oscillation (NAO) is considered to be the dominant mode of winter atmospheric variability in the Northern Hemisphere (Barnston AG, Livezey RE. 1987.

Although the reconstructed values are generally lower than the instrumental values during the calibration period (1863–1983), the final reconstruction does capture the low frequency of the instrumental NAO.

The variability in the reconstructed NAO is also discussed within the context of lengthy regional climate records. Results suggest that the occurrence and length of the recent persistently high phase of the NAO are not unusual over the 555‐year period of time, but that the magnitude of some of the instrumental values may, in fact, be unique.
