The vertical structure of internal tide dissipation rate ϵ is essential to the parameterization of the internal tide‐induced mixing, yet its diversity has always been oversimplified in ocean circulation models. Based on a high‐vertical‐resolution (10 m) simulation around the exits of the Indonesian throughflow, the diversity in ϵ profiles near both the bottom and the thermocline was investigated by a hierarchical clustering classification. Five typical near‐bottom vertical structures of ϵ were found, of which the bottom‐intensified structure is dominant. From the maximum dissipation depths to the shallower water, all five profiles obey the same decaying function. There are three typical near‐thermocline structures of ϵ: one menifests the thermocline‐intensified pattern and the other two feature a surface‐intensified pattern characterized by a monotonic increase from 500‐m depth to the surface. All three vertical structures near thermocline could be scaled by the reciprocal of the Richardson number.

高分辨率非静水模型模拟的印尼通流出口内部潮汐消散速率垂直结构的多样性

内部潮汐消散率的垂直结构对于内部潮汐引起的混合参数化至关重要，但是在海洋环流模型中，其多样性总是被过分简化了。基于印度尼西亚通流出口周围的高分辨率（10 m）模拟，通过分层聚类分类研究了底部和温跃层附近的ϵ剖面的多样性。发现了typical的五个典型的近底垂直结构，其中底部增强结构占主导地位。从最大消散深度到较浅的水面，所有五个剖面都遵循相同的衰减函数。typical具有三种典型的近热线结构：一个显示了温跃线增强的图案，另外两个显示了表面增强的图案，其特征是从500-m深度到表面单调增加。接近温跃层的所有三个垂直结构都可以通过理查森数的倒数来缩放。
