Where is the North Atlantic Oscillation measured?
Quick Answer
The North Atlantic Oscillation is measured over the North Atlantic between the subtropical high near the Azores and the Icelandic low. It is not a single place, but a pressure pattern across the ocean basin.
The Full Story
The North Atlantic Oscillation, or NAO, is a climate pattern measured across the North Atlantic region. It compares atmospheric pressure near the Azores and near Iceland, which helps describe shifts in storm tracks and winds. When the NAO is in one phase, western Europe may get milder, wetter winters; in the other, colder conditions can be more likely. Because it spans a large area, it is best understood as a basin-wide pattern rather than a single location.
