【Abstract】 In order to evaluate the ability of the third generation of IAP / LASG global ocean general circulation model to simulate the interannual variability in the tropical Pacific during the l980s, espec- ially the El Nino and La Nina events, we adopt three datasets of wind stress to force the model. Then, the simulated results are compared with NCEP ocean assimilation data. Analyses show that there are a lot of common characteristics between the model ’s response to wind stress and NCEP ocean assimila- tion data in SST distribution, description of thermocline, and El Nino and La Nina events. However, the model’s response is not accurate in SST anomaly poleward of l0°N and l0°S and depicting seasonal cycle. In addition, the simulated temperature anomaly lags NCEP ocean assimilation data by about two months.更多还原
