本文在仅考虑铅直湍流的情况下,提出一种计算海流流速及予报海流流速的理论及方法。是在海流基本上是由海洋内部密度分布及海面风力和气压作用下形成的认识下,依据一定的事实,先行确定水平压强梯度力及铅直湍流动力粘滞系量,而后计算定常恒速海流及予报海流流速的。在建立海流流速予报方程解时,除了要求得流速随时间变化的解,尚需求得海水密度随时间变化的解。在海水密度随时间的变化予知的情况下,即可依据予知的风速及降水、蒸发差等随时间的变化,予报海流。曾对东中国海黑潮流系进行了定常恒速水平流速的计算。
In this paper, only the vertical turbulence is considered, a theory and method to calculate the velocity of the ocean current and to report the velocity of the ocean current are proposed. Based on the fact that the ocean current is basically formed by the density distribution within the ocean and the wind and air pressure from the sea surface, the horizontal pressure gradient force and the vertical turbulent dynamic viscosity coefficient are determined first, and then the steady constant velocity ocean current And to report the current flow rate. In establishing the solution to the current velocity of the ocean current, the solution of the seawater density over time is required in addition to the solution that requires the velocity to change over time. When the density of seawater changes with time, the current can be reported according to the change of the wind speed, precipitation, evaporation and other changes with time. A steady-state constant-velocity horizontal flow rate calculation was made for the East China Sea Kuroshio Current.
