A Dynamic Simulation Method for Computing Real-time Tidal Mixing

Abstract

The invention discloses a dynamic simulation method for calculating real-time tidal mixing: the Princeton ocean model provides initial flow field and density data for the tidal mixing parameter calculation model through a coupler, and the tidal mixing parameter calculation model uses the obtained flow velocity and density data to calculate Tidal mixing parameters, and the mixing parameters are fed back to the Princeton ocean model through the coupler; the Princeton ocean model operates under the condition of considering the influence of mixing parameters and outputs the flow velocity and density data of the second stage, and then passes them to the calculation model of tidal mixing parameters , so that the tidal mixing parameter calculation model receives the flow velocity and density data including the influence of tidal mixing; and so on, the addition of tidal mixing parameters affects and changes the tidal current velocity and density, and the change of tidal current velocity and density directly determines the mixing The size of the parameter. The invention can realize the dynamic simulation of the physical ocean model, and improves the defect of setting the mixing parameters as fixed values ​​in the original physical ocean model.

Description

technical field [0001] The invention relates to the field of physical ocean, in particular to a dynamic simulation method for calculating real-time tidal mixing, which is applied to dynamic real-time simulation of physical ocean models. Background technique [0002] The phenomenon of tidal mixing is that the tidal current flows through the rough seabed terrain and transforms into baroclinic tide in the form of internal wave. Part of the baroclinic tidal energy is radiated in the form of internal wave, and the rest is dissipated at the point where the internal wave is generated, thereby generating an enhanced tidal wave. Turbulent mixing. Tidal mixing occurs in the ocean all the time, and plays a key dynamic role in controlling the water quality characteristics and deep circulation characteristics of the ocean. It will have a great impact on ocean circulation, sea surface temperature and climate. It provides half of the energy source, is the main physical process of material...

AI Technical Summary

Problems solved by technology

[0003] The strength of tidal mixing is generally expressed by the size of the mixing parameter. The current existing research regards the tidal mixing parameter as a fixed value, which is inconsistent with the actual mixing phenomenon in the ocean, and does not take into account the constant The ongoing impact of ongoing mixing does not capture the dynamics of the mixing process
