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.

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.

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.

2022年9月9日 · The Pacific Decadal Oscillation (PDO), first defined by Mantua et al. (1997), is the dominant year-round pattern of monthly sea surface temperature (SST) anomalies in the North Pacific obtained via Empirical Orthogonal Function (EOF) analysis.

The "Pacific Decadal Oscillation" (PDO) is a long-lived El Niño-like pattern of Pacific climate variability. While the two climate oscillations have similar spatial climate fingerprints, they have very different behavior in time.

太平洋十年振盪 （英語： Pacific Decadal Oscillation，縮寫：PDO），又稱 太平洋年代際振盪[1] 或 太平洋十年間振盪[2]，是一种約以10年為周期尺度的太平洋气候变化现象。 变换周期通常为20～30年。 PDO的特征为太平洋北纬20度以北区域表层海水温度异常偏暖或偏冷。 在太平洋十年振盪“暖相位”（或“正相位”）期间 西太平洋 偏冷而 东太平洋 偏暖，在“冷相位”（或“负相位”）期间西太平洋偏暖而东太平洋偏冷。 美国海洋学家Steven R.Hare 于1997年在研究 鲑鱼 繁殖现象 …

太平洋十年涛动（Pacific Decadal Oscillation, PDO）是一种以10年周期尺度变化的太平洋气候变化现象。 变换周期通常为20～30年。 PDO的特征为太平洋北纬20度以北区域表层海水温度异常偏暖或偏冷。

The PDO is a long-term (10-20 year) oscillation of the Pacific Ocean in response to the changes in the atmosphere. During a warm (positive) phase, the response of the ocean to low atmospheric pressure over the Aleutian Islands causes ocean currents to bring warm waters in the Eastern Pacific Ocean and along the coast of North America and cool ...

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.
