PDO (Pacific Decadal Oscillation)

The Pacific Decadal Oscillation (PDO) is a long-term climate pattern in the North Pacific Ocean that lasts about 20 to 30 years. It involves changes in sea surface temperatures, affecting weather and climate in North America and beyond. The PDO has two phases: a "warm" phase, where the ocean surface is warmer, and a "cool" phase, where it is cooler. These shifts can influence rainfall, storm patterns, and temperatures, impacting agriculture, ecosystems, and weather trends. Understanding the PDO helps scientists predict climate variations and their potential effects on different regions.
