本文引入质量输送概念,利用三次实测余流、密度、深度和风的资料,分离出常流质量输送和风海流质量输送两部分的六个要素,归纳了过去的风海流圆和椭圆分离法。以东海北部近岸的A站为例,提出了根据风速、风向查对和计算各层风海流的表格形式,供预报余流之用。实测余流与预报值比较,结果较好,量值正确率平均为78％,方向误差为31°。 In this paper, we introduce the concept of mass transport, and use the data of three measured residual, density, depth and wind to separate the six components of the normal mass flow and the mass flow of the ocean current and the past wind and ellipse separation methods. Taking station A near the north coast of the East China Sea as an example, a table form for wind flow and wind direction checking and calculation of the wind currents in each layer is put forward for the prediction of residual flow. The measured residual flow and forecast value, the result is better, the average accuracy of the value of 78%, the direction of error of 31 °.
