摘要: Miami Isopycnal Coordinate Ocean Model (MICOM) is applied here to simulate the interdecadal climatic change in the Pacific Ocean. The surface forcing functions from January 1945 through to December 1993 are derived from the Comprehensive Ocean and Atmospheric Data Set (COADS). Such a numerical experiment reproduces the observed basin-wide evolution for the interdecadal variability of the heat content in the upper 400 m layers. The teleconnections between the central North Pacific, the Gulf of Alaska, and the eastern and western tropical Pacific Oceans are captured very well. Two additional experiments are performed to investigate the relative importance of anomalous wind and buoyancy forcing regarding the regime shift. The results show that the anomalous buoyancy forcing is the dominant factor in the North Pacific and the subtropics, whereas the anomalous wind forcing is more important in the tropical Pacific than the other factors. Subduction is intrinsic physics for the interdecadal variability in the midlatitudes and the northern subtropics, whereas other mechanisms are involved in the tropical Pacific.
