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 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 …

2022年9月9日 · The Pacific Decadal Oscillation (PDO) is defined by the leading pattern (EOF) of sea surface temperature (SST) anomalies in the North Pacific basin (typically, polewards of 20°N). The SST anomalies are obtained by removing both the climatological annual cycle and the global-mean SST anomaly from the data at each gridpoint.

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.

2021年8月10日 · The monthly PDO index, ranging from 1900 to present, is retrieved from the Joint Institute for the Study of the Atmosphere and Ocean (JISAO), University of Washington: http://research.jisao.washington.edu/pdo/, which is defined as the leading principal component of monthly SST variability over the North Pacific (north of 20°N).

2013年4月2日 · [1] The Pacific Decadal Oscillation (PDO) has been shown to have significant climatic and environmental impacts across the Pan-Pacific Basin; however, there are no records of PDO activity from the South China Sea (SCS), the largest marginal sea in the northwest Pacific Ocean. This study suggests that a series of geochemical profiles obtained ...

2014年11月7日 · At times, phases of PDO are uncertain. For example, in winter 2013–2014, the PDO index from Joint Institute for the Study of the Atmosphere and Ocean (JISAO) indicated that the PDO transited to a positive phase, while PDO indices from other three centers remained in a …
