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. 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. This climate pattern also affects coastal sea and continental surface air temperatures from Alaska to California.
During a "warm", or "positive", phase, the west Pacific becomes cooler and part of the eastern ocean warms; during a "cool" or "negative" phase, the opposite pattern occurs. The Pacific (inter-)decadal oscillation was named by Steven R. Hare, who noticed it while studying salmon production pattern results in 1997.
Video... O’Neill said the PacificOcean off the Oregon Coast was in a period of Pacific Decadal Oscillation that frequently brings heavier rain than normal, in addition to the formation of a weak La Nina, which also favors wetter-than-normal conditions.
It is part of the PacificTyphoonBelt, and has an active typhoon season that ...Instead, Basconcillo and Moon’s paper links it to the Pacific Decadal Oscillation—which, according to the U.S.
... factors that influence climate — things like changes in the sun’s brightness, major volcanic eruptions, and cycles such as El Niño and the Pacific Decadal Oscillation,” the q-and-a states.
However, the cooling effect of La Niña will still be felt in western and northwestern Canada where it is reinforced by the Pacific Decadal Oscillation, a long-term fluctuation in Pacific Ocean...
Factored in with a weak La Niña, Merrill noted a cool phase of the Pacific-Decadal Oscillation leading to a warmer than average winter in our area. That oscillation is about the configuration of sea ...
Another natural pattern known as the Pacific Decadal Oscillation (PDO) can lead to swings in sea surface temperatures in the Pacific Ocean between the northern latitudes of 20 and 60 degrees. Since 2016, B.C.
In addition, the shift of bifurcation latitude of the North Equatorial Current, the phase transition of the Pacific Decadal Oscillation and El Niño-Southern Oscillation have also influenced the changes of the Kuroshio, according to the researchers.
... large-scale weather anomaly known as the Pacific Decadal Oscillation (PDO), which is in the cold phase and so reinforces the idea that our winter will likely be colder and snowier than average.
With that said, the predicted La Niña may happen within the context of a larger climate event, a resurgence of a cool phase of the basin-wide Pacific Decadal Oscillation... A multi-year Pacific Decadal ...
...Pacific, while convergence occurs over the western Pacific ... This effect is further linked to the phase of the Pacific Decadal Oscillation (PDO), a long-term climate pattern in the Pacific Ocean.
The researchers combined the information with environmental data about factors that affect the whales’ foraging grounds, including the Pacific Decadal Oscillation, a fluctuation in sea temperatures ...
Two proxies of habitat quality, the mean Pacific Decadal Oscillation index and the mean ratio between upwelling intensity and the number of relaxation events, were highlighted; these are thought to be ...
Their overall condition is worse compared to their ENP (Eastern NorthPacific) counterparts ... the mean Pacific Decadal Oscillation index, and the mean ratio between upwelling intensity in a season and the number of relaxation events.
Zhou and colleagues suggest that the Arctic internal mode is likely to shift to a negative phase and Interdecadal PacificOscillation to a positive one in the coming decades, which would lead to a ...
