Definition
- [Céline Bonfils] The pacific decadal oscillation (PDO) is a mode of natural decadal climate variability, typically\ defined as the principal component of North Pacific sea surface temperature (SST) anomalies. To\ remove any global warming signal present in the data, the traditional definition specifies that\ monthly-mean, global-average SST anomalies are subtracted from the local anomalies. Differences in\ the warming rates over the globe and the PDO region may therefore be aliased into the PDO index... , "[HE Juanxiong] Pacific Decadal Oscillation (PDO) is a long-term ENSO-like variability of the North Pacific. It is\ the first principal component of EOF of the North Pacific SST. ENSO is the strongest signal of\ annular change of global climate system. Empirical Mode Decomposition (EMD) method is applied to two\ types of indices. One type of index is the Pacific Decadal Oscillation (PDO) index that represents a\ long-term ENSO-like variability of the North Pacific...
