Basin‐Width Dependence of the Meridional Width of Ocean Striations

Abstract The investigation of ocean striations holds significant value for a comprehensive understanding of the complex multi‐scale ocean circulations and the transfer of energy and matter between them. Through comparative studies of the open oceans and marginal seas, we have identified notable differences in the meridional width of ocean striations between these two environments. The fundamental cause of this discrepancy lies in the distribution of energy in wavenumber space, where broader basins typically support energy aggregation at larger scales, whereas narrower basins may lead to energy concentration at smaller scales. This paper also employs an idealized isopycnal layer model, and the sensitivity experiments by varying basin‐widths substantiate this perspective. The research presented herein further advances the experimental study on the meridional width of ocean striations.
