以1958~2001年ERA40风应力强迫分辨率为0.5×0.5的准全球海洋环流模式LICOM1.0, 建立了高分辨率印度尼西亚海上层环流的长时间序列. 模拟结果合理再现了以望加锡海峡为印度尼西亚贯穿流(ITF)主要通道的基本流场. 模拟ITF年平均流量14.5 Sv, 其中上层700 m年平均流量13.2 Sv. ITF流量的季节变化主要是年周期信号. 与观测结果相比, 模拟ITF流量的年平均值与季节变化特征都是合理的. 模拟ITF流量年际异常与Ni駉3.4指数有显著的负相关(-0.65), 太平洋的年际异常是影响ITF流量变化的主要因子. 模拟结果中, ITF流量与太平洋、印度洋年际异常的关系不是固定不变的, 在某些年份(例如1994年), 印度洋偶极子(IOD)强信号对ITF流量的影响超过了ENSO信号的影响.
A long-time series of high-resolution sea circulation in Indonesia was established by the quasi-global ocean circulation model LICOM1.0 with an ERA40 wind stress forcing resolution of 0.5 × 0.5 from 1958 to 2001. The simulation results reproduce the long- The basic flow field of the main channel of ITF in Indonesia simulates the annual average flow rate of 14.5 Sv in ITF, of which the average flow rate in the upper 700 m is 13.2 Sv. The seasonal variation of ITF flow is mainly annual period signal. Compared with the observed results, Both the annual mean and seasonal variations of the flow rate are reasonable.The inter-annual anomaly in the simulated ITF flow is significantly negatively correlated with the Ni 駉 3.4 index (-0.65), and the interannual anomalies in the Pacific Ocean are the major factors affecting the ITF flow rate. As a result, the relationship between ITF flux and the interannual anomalies in the Pacific and Indian Oceans is not constant. In some years (eg, 1994), the impact of strong Indian Ocean dipole (IOD) signals on ITF flows exceeded that of ENSO signals .
