The Pacific Decadal Oscillation (PDO) is a long-term fluctuation that occurs in the Pacific Ocean every 20 to 30 years that is characterized by variable sea-surface temperatures in the north-central Pacific and near the Gulf of Alaska. Atmospheric conditions can (and do) influence the ocean and the ocean influences the atmosphere. Some of them have much more of an impact on climate and weather patterns in the U.S. and elsewhere than ENSO. the repair of D.N.A. He has written dozens of scientific research papers and has appeared in a number of film and television documentaries, including programs for National Geographic, Discovery Channel, BBC, and numerous television networks. This mass of warm water is what causes climatic change around the world. A positive or “warm” phase brings about greater-than-average sea-surface temperatures and greater precipitation in the western Indian Ocean region, along with a corresponding cooling of waters in the eastern Indian Ocean that tends to bring reduce precipitation in Indonesia and Australia.
