The ocean contains various spatiotemporal scales of motion processes, and ocean striations are a newly discovered form of flow in recent years. This flow phenomenon lies between geostrophic turbulence and quasi-steady flow. Due to the dominance of large-scale motion in the upper ocean, ocean striations are masked and need to be extracted using filtering methods. In this study, the three-dimensional structure of ocean striations in the North Pacific was extracted based on zonal velocity data using Chebyshev high-pass filtering. The “flow stability” index was defined to quantitatively analyze the barotropic feature of ocean striations in the North Pacific, thereby deepening the understanding of the structural characteristics of ocean striations in the North Pacific.
