WebAug 30, 2009 · Highlights. The North Atlantic Oscillation (NAO) Index describes changes in the strength of two recurring pressure patterns in the atmosphere over the North Atlantic: a low near Iceland, and a high near the Azores Islands. Positive NAO index values indicate these features are strong, creating a big pressure difference between them.
