WebThe low-level GN model (Level I GN model or called the GN-1 model) is a weakly dispersive, strongly nonlinear wave model. As the level goes up, the high-level GNmodel becomes a strongly dispersive ... WebFor a=h2 = 0:91, we use the same method to simulate internal waves.The amplitude of initial wave is a = 0:91h2 = 0:1365m at t = 0s. At t = 550s, the snapshot of wave train is shown on the left of Figure 2. We found that the amplitude of the leading internal solitary wave is only 0:09358m.Then, we calculate the profile of internal solitary wave with a = 0:09358m …
