| Abstract: | Using CCSM3 model of NCAR,this study examines the results of control run and 130yr simulation run form year 1870 to 1999. The temperature varying trend of the Pacific Ocean area and the spatial-temporal structure of the North Pacific Decadal Oscillation (PDO) are analyzed by comparing model output with corresponding reanalysis data. The results indicate that the model simulates well many features of the observed PDO, the spatial distribution pattern of sea surface temperature anomaly are similar to the typical PDO. Especially when the trend of CO2 is considered in simulation, the three important phase-changing of SSTA in North Pacific Ocean in the 20th are well reproduced. The position of two core of temperature anomaly in subsurface are more eastern and deeper, and the temperature difference between east and west are reduced. The increasing of CO2 play an important role in elongating the period and phase-changing of simulated PDO, the position and intensity are also affected. |
