These mood swings include a climate phenomenon known as Pacific Decadal Oscillation, or PDO. It's an El Nino- like shift in the ocean's temperature that scientists once thought cycled every 15 to ...

Last week, I wrote a long story about a phenomenon called the Pacific Decadal Oscillation or PDO, a naturally occurring wobble in the planet’s climate system that involves the burial and release ...

Oscillation Rules As The Pacific Cools Date: December 12, 2008 Source: NASA/Jet Propulsion Laboratory Summary: The latest image of sea-surface height measurements from the U.S./French Jason-1 ...

During a PDO cold phase, the tropical Pacific Ocean temperatures are lower, and Australia's decadal rainfall tends to be above average. Under warm phases, the opposite occurs, with below average ...

The Pacific Decadal Oscillation describes water conditions in the tropical Pacific Ocean that drive global climate conditions. Scientists have long observed the PDO alternates between warm and cool ...

The Pacific Decadal Oscillation (PDO) varies over a broader range of timescales. The researchers looked only at the portion of the PDO that was multidecadal—what they term the Pacific ...

John Wheeler: Other factors besides La Niña point to a cold and snowy winter The Pacific Decadal Oscillation reinforces the idea that our winter will likely be colder and snowier than average.

Analysis by a team of meteorologists suggest another pair of atmospheric patterns, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation, or AMO and PDO, aren't real.

There are many factors that influence the globally averaged temperature. Greenhouse gases play a role, certainly. But other, natural forces have effects as well.

Move over El Nino: Scientists now have their eyes on another, stronger climate pattern that could deliver rain to Southern California for years.
