| 摘 要： | 作者运用简化的η坐标 POM模式数值研究了地形对东海黑潮锋面弯曲的产生与成长的影响。平底时 ,小扰动迅速发展导致锋面出现大弯曲。考虑到地形因素和黑潮流核远离陆架的情况 ,因其锋区正处在陡的陆坡之上 ,斜压不稳定被减小 ,其锋面不会出现如观测所示的弯曲。结果表明 ,在该实验条件下 ,地形对锋面起到稳定作用

| Abstract: | Numerical studies of the Kuroshio frontal meanders in the East China Sea are carried out by using the η-coordinate POM model with the emphasis on the effects of cross-stream topography .The results show that perturbations grow in amplitude and form large frontal meanders for the flat bottom condition. After incorporating the topography, when the flow core of the Kuroshio located away from the continental shelf, the continental slope acts as a stable factor and all perturbations move out of the domain before developing into finite amplitude meanders. |
