Popis
The Arctic Oscillation (AO) is a leading teleconnection pattern in the Northern Hemisphere circulation. It is calculated as the first Empirical Orthogonal Function (EOF) for height anomalies poleward of 20 degrees latitude for the Northern Hemisphere. The goal of the EOF procedure is to capture the maximum amount of explained variance in the circulation fields.
