Dynamic simulation method for calculating real-time tidal mixing

Abstract

The invention discloses a dynamic simulation method for calculating real-time tidal mixing. The method comprises the following steps of: providing initial flow field and density data for a tidal mixing parameter calculating model through a coupler by a Princeton ocean model; calculating tidal mixing parameters by utilizing the obtained flow velocity and density data and feeding back the mixing parameters to the Princeton ocean model through the coupler by the tidal mixing parameter calculating model; and under the circumstance of considering the influence of the mixing parameters, operating the Princeton ocean model, outputting the velocity and density data of the second stage and transmitting to the tidal mixing parameter calculating model to ensure that the velocity and density data containing the influence of the tidal mixing are received by the tidal mixing parameter calculating model. So repeatedly, the tidal speed and density are affected and changed by the addition of the tidalmixing parameters and the size of the mixing parameters is directly determined by the change of the tidal speed and density. By means of the method disclosed by the invention, the dynamic simulation of a physical ocean model can be realized and the defect of setting the mixing parameters as fixed values in a conventional physical ocean model is corrected.

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
