| 摘 要： | 利用FVCOM海洋模型以及MM5气象模式预报风场,对渤海冬季三维风生环流进行了数值模拟,结果显示:渤海风生环流具有显著的三维结构,表层基本沿风向运动,量值在5~10 cm/s,海峡处流速可达15 cm/s,底层有明显的补偿流,量值<3 cm/s;深度平均流环流状态明显,渤海海峡海流北进南出,渤海中部以及辽东湾为一顺时针环流,渤海湾以及莱州湾基本呈逆时针环流。文章通过对比实验,进一步讨论了海面风应力以及海底地形对渤海环流的不同影响,得出:在渤海中部风应力的切变涡度是形成顺指针流型的主要驱动力;除渤海中部以外,渤海冬季流型受地形作用的影响要大于海面风场的切变涡度。

| Abstract: | FVCOM(the Finite-Volume Coastal Ocean Model) and MM5(the Meteorological Model 5) are used to simulate the wind-driven circulation during the winter in the Bohai Sea.The numerical results show that the wind-driven circulation has a significant 3-d structure: there is a wind-induced current in the surface with a value of 5~10 cm/s and its peak value is about 15 cm/s in the strait;meanwhile a significant compensating current with the value of less than 3 cm/s exists in the bottom.The vertically averaged curren... |
