| 摘 要： | 本文结合南沙群岛海域出现内潮的水文背景，建立了一个两层数值模式，并通过数值试验来探讨由正压潮波作用下的内潮产生机制。结果表明：底形效庆是促使内潮产生的重要因子；内潮心要在大陆坡产生，然后分别沿着大陆架和深海平原两个方向传播；内潮斜压流速的量级可与正压流速的相比拟。

| Abstract: | In the paper, based on the hydrologic background of the existence of internal tide inthe Nansba Islands sea area, a two-layer model is set up, and some numerical experiments are done to study the generation mechanism of internal tide forced by a barotropic tide wave; The results show that bottom topographic effect is an important factor for generation of internal tide; internal tide propagates in the direction of continental shelf and abyssal plain after forming in the continnental slope; the order of baroclinic tide speed can be compared with that of barotropic one. |
