Advances in Studies of Pacific Decadal Oscillation
太平洋年代际振荡的研究进展

This review summarizes major advances in the observational and theoretical studies of the Pacific Decadal Oscillation (PDO) phenomenon. The spatio-temporal structures of the PDO are described and three categories of existing theories or hypotheses associated with the large-scale air-sea interaction are compared and discussed. The problems and unresolved issues in these theories are proposed, and future prospects are suggested. Moreover, the interdecadal climate variabilities in East Asia and China are also reviewed and possible role of these variations in the PDO is also discussed.
