基于一组简化了的运动方程组，在充分考虑底Ekman层作用的情况下，提出一种横穿锋面的断面上流场结构的计算方法。应用该方法对东海横穿黑潮锋的不同断面上的流场（1989－1990年资料）进行计算。结果表明，黑潮锋左侧（向岸侧）存在较强的上升流，而锋区右侧（离岸侧）表现为海水的下降运动。垂直流速为（1－20）×10－3cm／s的量级，而横穿锋面方向的水平流速为1－3cm／s，其中以夏、秋季跃层附近最强。在陆架坡折处，上升流转向陆架。同时，还分析了正压场和斜压场对这种流场的不同贡献，认为在黑潮区，正压场起主要作用;而在内陆架区，斜压场则变得重要。将计算的流场与硝酸盐的分布比较表明，两者有较好的对应关系。
Based on a simplified set of equations of motion, a method of calculating the structure of the flow field across the frontal plane is presented considering the effect of the bottom Ekman layer. This method is used to calculate the flow field (1989-1990 data) on different sections across the Kuroshio front in the East China Sea. The results show that there is a strong upwelling on the left side of the Kuroshio front (to the shore), while the right side (off shore side) of the front shows the descending movement of seawater. The vertical flow rate is on the order of (1-20) × 10-3cm / s, and the horizontal velocity across the frontal plane is 1-3cm / s, with the strongest around the summer and autumn thermocline. At the slope of the shelf, the ascent flows to the shelf. At the same time, the different contributions of positive pressure field and baroclinic pressure field to this flow field are also analyzed. It is considered that the positive pressure field plays a major role in the Kuroshio area, while the baroclinic field becomes more important in the inland shelf area. Comparing the calculated flow field with the nitrate distribution shows that there is a good correspondence between the two.
