摘要

摘要: 本文采用Regional Ocean Modeling System（ROMS）来研究西南黄海夏季环流，模拟的结果与浮标和锚定观测符合的很好。表层的海流流向东北，离岸一侧的流速大于近岸的流速，表层以下为约沿着25米等深线的气旋式流动。我们通过一系列过程导向实验研究海表风应力和底层温度锋面对环流的影响，结果表明，东南风驱动了表层东北向流动，底层温度锋面驱动了表层以下气旋式流动。底层温度锋面形成于近岸垂向混合充分水体和离岸层化水体之间。

Abstract: The Regional Ocean Modeling System (ROMS) is used to study the summer circulation in the southwestern Yellow Sea (SWYS). The modeled currents show good agreement with observations from both drifters and moorings. While the summer current in the SWYS flows consistently northeastward on the surface with large magnitude offshore, the current below the surface layer features a cyclonic circulation roughly along the 25 m isobath. The effect of a surface wind stress and bottom thermal fronts on the circulation is investigated through a series of process-oriented numerical experiments. It is found that the southeasterly wind dominates the surface current, whereas the bottom thermal fronts, which are formed in a transition area between the vertically well-mixed region and the stratified region, are responsible for the cyclonic circulation below the surface.
