Description

technical field [0001] The invention belongs to the field of modeling fusion of physical ocean and underwater sound field, and relates to a parallel coupled ocean acoustic forecast system and an operation method. Background technique [0002] At present, various sound propagation models have been established at home and abroad. According to the different numerical solutions to the wave equation, various models can be roughly divided into normal wave models, ray models, parabolic equation models and some joint models. The sound field model alone has developed relatively mature in terms of calculation. However, most of the existing calculations in the field of sound field are serial, and there are relatively few studies on parallel algorithms. When dealing with small-scale two-dimensional sound propagation problems, the existing sound field calculation models can meet the actual needs. However, in recent years, with the demand for three-dimensional sound propagation problems...

AI Technical Summary

Problems solved by technology

However, research on the intersection of oceanography and acoustics is still scarce

The existing sound field models only have the function of simulation calculation, but not the function of underwater sound field prediction

Moreover, the calculation scale of the existing research results at this stage is small, and there is no large-time-span forecasting system applicable to the global ocean acoustic field at home and abroad.
