摘要: |
日本南部黑潮处于半封闭的海域,是一种下游受伊豆诸岛约制的强迫急流,本文在Masuda工作基础上讨论两种边界条件:解出了最终路经曲线,由两种边界条件结果的比较可知,选取第二种边界条件结果更符合实际;与无外强迫的解对照,说明了伊豆诸岛在双流态形成中的贡献。这两方面结论都反映出局地效应和非线性效应对双流态形成的重要作用。 |

Abstract: |
Flowing in a semi-enclosed sea, the Kuroshio south of Japan is a jet forced by Isu Islands downstream. Based on Masuda’s work, the present paper discusses two kinds of boundary conditions, (For the equations please see the PDF file.) for the path curves, study of which show that the second one is more resonable than the first one. Comparison of the results with the force of Isu Islands and with no force downstream reveals that attribution of Isu Islands as the downstream external forece leading to the formation of the bimodality is important. The results of study on the above two aspects reflect that both the local factor and nonlinearity exert important effects on the formation of the bimodality of the Kuroshio south of Japan. |
