Modeling of Propagating Long Internal Waves in an Inhomogeneous Ocean: the Theory and its Verification

Talipova T.G., Pelinovsky E.N.

An asymptotic model of long internal wave transformation in horizontally inhomogeneous ocean is discussed. This model is based on the Gardner equation (extended Koreweg – de Vries equation). Verification of the model using the ocean experimental data from the SEASAM experiment on the Malin shelf is carried out. It is shown that the model is appropriate for rough estimation of amplitudes and shapes of internal waves. The ad-vantage of the model is related to the simplicity of accounting for the horizontal inhomogeneity of hydrological fields and short time needed for calculations.
