According to the forecasting method disclosed by the invention, an automatic operation coupling mode can be realized, the efficiency of a forecasting system is improved, and a forecasting result is more visual and friendly.

Description

technical field [0001] The invention relates to a storm surge-sea wave coupling forecasting method, in particular to a visualized storm surge-sea wave coupling forecasting method. Background technique [0002] Both storm surges and ocean waves are marine processes driven by the atmosphere. They often occur simultaneously and interact with each other near the coast. When encountering extreme weather such as cold waves or typhoons, the two are likely to cause marine disasters. Numerical simulation is a very important means in the forecast of storm surge and sea waves, but the current numerical simulations basically use a single wave model or storm surge model, without considering the interaction between storm surge and sea waves.

Problems solved by technology

In the forecast of storm surge and sea wave, numerical simulation is a very important means, but the current numerical simulation basically adopts a single wave model or storm surge model, without considering the interaction between storm surge and sea wave

In addition, most of the current operational storm surge and wave models use orthogonal curve grids instead of unstructured grids, and the description of complex coastlines is not fine enough

[0003] Moreover, in the operational operation of storm surge and sea waves, the general steps are to first prepare the atmospheric forcing field, then run the numerical model, and finally analyze and draw the simulation results. The entire process is basically done manually, and the degree of automation is not high. Affects the forecasting efficiency, and when displaying the forecast results, the plane distribution map is used, and the display form is not intuitive and friendly enough

[0004] Therefore, the existing numerical forecasting methods have the problems of low degree of automation and operating efficiency, insufficient model resolution, imperfect physical mechanism, and unfriendly and intuitive display of forecast results.
