Understanding the Pacific Decadal Oscillation: A Guide for Wear OS Users

The Pacific Decadal Oscillation (PDO) is a long-term climate pattern in the Pacific Ocean, characterized by shifts in sea surface temperatures and atmospheric pressures. These shifts occur in phases lasting 10 to 20 years, significantly impacting weather patterns across the Pacific region.

What Is the Pacific Decadal Oscillation?

The PDO is a recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific Ocean basin. It is detected as warm or cool surface waters in the Pacific Ocean, north of 20°N. Over the past century, the amplitude of this climate pattern has varied irregularly at interannual-to-interdecadal time scales. There is evidence of reversals in the prevailing polarity of the oscillation occurring around 1925, 1947, and 1977; the last two reversals corresponded with dramatic shifts in salmon production regimes in the North Pacific Ocean.

Phases of the PDO

The PDO has two primary phases:

• Positive (Warm) Phase: During this phase, the western Pacific becomes cooler, and the eastern Pacific warms. This pattern is associated with increased sea surface temperatures along the North American coast, leading to warmer and wetter conditions in regions like the Pacific Northwest and Alaska. (psl.noaa.gov)

• Negative (Cool) Phase: In contrast, the negative phase features cooler sea surface temperatures along the North American coast and warmer temperatures in the central and western Pacific. This phase is linked to cooler and drier conditions in the same coastal regions. (psl.noaa.gov)

Impacts of the PDO

The PDO influences various climatic and ecological aspects, including:

• Temperature and Precipitation: The PDO affects coastal sea and continental surface air temperatures from Alaska to California. (en.wikipedia.org)

• Ecosystems: Shifts in the PDO have been linked to changes in salmon production regimes in the North Pacific Ocean. (en.wikipedia.org)

• Drought Patterns: The PDO, along with the Atlantic Multidecadal Oscillation (AMO), strongly influences multidecadal drought patterns in the United States. (en.wikipedia.org)
