Content abstract: the northern south China sea is a high incidence of the internal waves, and in view of the difficulties of measurement in the south China sea wave, with the method of machine learning to identify internal waves on satellite remote sensing images in the mark on the surface of the sea, satellite image data, based on more than 10 years of analysis in the northern south China sea wave distribution characteristics and laws of space and time, in the northern south China sea wave is given of the satellite image information database.
Aiming at the propagation and evolution law of large amplitude internal solitary wave, a flume experiment of strong layered internal wave was carried out. Based on the collapse wave generation, the propagation and evolution law of internal solitary wave was analyzed, and the fully nonlinear evolution simulation calculation of two-dimensional two-layer fluid was carried out. PIV was used to measure the flow field information of internal wave passing through and the flow field on the changing terrain.
The effect of internal wave and structure is investigated by numerical simulation.
