摘要
首先应用IAP/LASG GOALS气候模式的多年积分的结果,对赤道中西太平洋和印度洋的SST和纬向风场进行分析, 发现在模式中也同样存在与观测资料分析结果相似的“印太齿轮式耦合”。基于此, 设计了赤道太平洋和印度洋海域纬向风应力异常的4 组敏感性试验, 去研究太平洋和印度洋海气相互作用的联系。结果表明, 在太平洋或印度洋上的大气异常信号通过印- 太齿轮组合(GIP) 作为桥梁(atm ospheric bridge), 影响到另一地的海气相互作用, 从而将太平洋上的ENSO 类年际变率信号与印度洋环流和亚洲季风纬向分量的变化联系起来。
The analysis of the muti-year integrations from the global climate model IAP/LASG GOALS shows that the gear-like connection in the air-sea interaction between the equatorial Indian and Pacific Oceans, “GIP” in short, is well represented in the model Sensitivity experiments were then designed to further investigate such GIP connections Results reveal that, through such kind of gearing, the air-sea interaction in one ocean basin forced by the zonal-wind stress anomaly causes the air-sea interaction in the other ocean, and then results in anomalous SST there Therefore, the “GIP” is considered to be the atmospheric bridge linking the ENSO over the Pacific Ocean on one side and the zonal wind component of the Asian monsoon over the Indian Ocean on the other
