题目：Nonlinear calculations of directional ocean surface waves and internal waves

摘要：We discuss a nonlinear method in three dimensions for ocean surface waves and interfacial waves. The strongly nonlinear, temporal method is based on integral equations and use of Fourier transform. Its efficient solution makes possible a large set of unknowns. In the first part of the talk, the method is used to calculate the kinematics of directional ocean waves in storm conditions, where the surface elevation has been measured of large horizontal domains. In the second part of the talk, the method is developed for the dead water problem and interfacial wave formation in geophysical applications.
