6 days ago · The Pacific Decadal Oscillation (PDO) is often described as a long-lived El Niño-like pattern of Pacific climate variability (Zhang et al. 1997). As seen with the better-known El Niño/Southern Oscillation (ENSO), extremes in the PDO pattern are marked by widespread variations in the Pacific Basin and the North American climate.

PDO is defined as the leading EOF of monthly SSTA in the North Pacific, between 20N-70N. SST monthly climatology is removed and then the global mean is removed. Climatology is 1920-2014.

Sep 9, 2022 · Concise description of a spatially coherent, large-scale mode of decadal climate variability across the Pacific basin. Robust pattern across many datasets (e.g. HadISST, ERSST, Kaplan SST, etc.) and also simulated in models.

Two main characteristics distinguish PDO from El Niño/Southern Oscillation (ENSO): first, 20th century PDO "events" persisted for 20-to-30 years, while typical ENSO events persisted for 6 to 18 months; second, the climatic fingerprints of the PDO are most visible in the North Pacific/North American sector, while secondary signatures exist in ...

The Pacific Decadal Oscillation (PDO) is a long-term ocean fluctuation of the Pacific Ocean. The PDO waxes and wanes approximately every 20 to 30 years. From ocean surface topography data, together with other ocean and atmospheric data, scientists can determine whether we are in a ‘cool’ phase or a ‘warm’ phase.

What is the Pacific Decadal Oscillation? The PDO is a long-term (10-20 year) oscillation of the Pacific Ocean in response to the changes in the atmosphere.

Pacific Decadal Oscillation (PDO) The Pacific Decadal Oscillation is a pattern of climate variability with a similar expression to El Niño, but acting on a longer time scale, and with a pattern most clearly expressed in the North Pacific/North American sector.

The Pacific decadal oscillation (PDO) is a robust, recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific basin. The PDO is detected as warm or cool surface waters in the Pacific Ocean, north of 20°N.

The PDO is defined as the leading EOF of mean November through March SST anomalies for the Pacific Ocean to the north of 20N latitude. For the EOF calculation, the global mean SST anomaly was first removed for each month in order to reduce …
