A Research on the North Pacific Oscillation
Abstract：The North Pacific Oscillation is a conspicuous seesaw-like low-frequency oscillation in the north hemisphere atmosphere.The evolution of the NPO directly affects not only the evolution of weather and climate near the North Pacific but even the entire Northern Hemisphere circulation anomalies and abrupt climate change.In this paper,a general survey was conducted to sum up the characteristics of the time and regional evolution of the NPO,the common calculation method,the defining method of the NPO index,and the impacts on the climate and weather.Then some scientific questions need solving were expounded.Finally it was pointed out that some mature research methods in other oscillation studies might serve as useful references since the NPO study is still in the beginning stage.
