| 摘 要： | 使用1994～2000年NCEP风应力资料驱动全球变网格环流模式，得出印度尼西亚贯穿流(ITF)流量的年际变化时间序列。模拟结果显示：ITF流量的年际变化与太平洋和印度洋的年际变化均有密切联系，在El Ni~↑no年流量偏低，在La Ni~↑no年流量偏高；ITF流量的年际变化与Ni~↑no 3区指数呈显著负相关，Ni~↑no 3区指数超前ITF流量2个月时负相关系数达到最大，为-0．81；与南方涛动指数(SOI)明显呈正相关，SOI超前ITF流量2个月时相关系数达到最大，为0．72；与印度洋偶极子(IOD)指数负相关，IOD指数超前ITF流量3个月时负相关系数达到最大，为-0．74。

| Abstract: | A variable-grid global circulation model driven by NCEP wind stress data from 1994 to 2000 was used to get the interannual variation time series of the Indonesian Throughflow (ITF). It is shown from the simulated results that the interannual variations of ITF volume transport are closely realted to the interannual variations of the Pacific Ocean and Indian Ocean, the ITF volume transport was smaller during E1 Nio event, and larger during La Nia event. The interannual variations of ITF volume transport are negatively correlated with those of Nio 3 area index, and their negative correlation coefficient reached the maximum of -0.81 when the Nio 3 area index led the ITF volume transport by 2 months; the interanual variations of ITF volume transport are correlated with those of Southern Oscillation index (SOI), and their correlation coefficient reached the maximum of 0.72 when the latter led the former by 2 months; the interannual variations of ITF volume transport are negatively correlated with those of Indian Ocean Dipole index, and their negative correlation coefficient reached the maximum of -0.74 when the latter led the former by 3 months. |
