摘要：

印尼贯穿流（ITF）连通着太平洋和印度洋，且具有显著的时空变化特征，但现有再分析数据集对其描述的能力尚不清楚。利用布放在入流和出流的系泊潜标，对多套再分析数据模拟的ITF流场结构、最大流速、最大流速深度等要素变化特征进行验证。结果表明：CMEMS再分析数据表现较好，在望加锡海峡、帝汶海峡和翁拜海峡处与观测数据的相关系数分别为0.70、0.50和0.42，能够再现ITF对气候事件的响应；HYCOM再分析数据表现次之，其主要缺点是不能模拟出帝汶海峡和翁拜海峡300 m以下的流场结构；OFES再分析数据对望加锡海峡和翁拜海峡流速的模拟均偏小。

The Indonesian Throughflow（ITF） connects the Pacific Ocean and the Indian Ocean, which has the flow field with significant spatiotemporal variation. However, the ability of existing reanalysis datasets to describe the ITF is unclear. The ITF flow field structure, maximum velocity and maximum velocity depth of the reanalysis data are verified by using the mooring submerged buoys placed in the inflow and outflow. The results show that the CMEMS reanalysis data has a good performance, and the correlation coefficients between it and the mooring data in Makassar Strait, Timor Strait and Ombai Strait are 0.70, 0.50 and 0.42, respectively. And it can reproduce the response of ITF to climate events. In contrast, the HYCOM reanalysis data cannot simulate the flow field structure below 300 m in Timor Strait and Ombai Strait. The OFES reanalysis data has relatively smaller flow velocity in Makassar Strait and Ombai Strait.
